Irem from Turkey shares her groundbreaking work in TensorFlow and advice for the community

Posted by Jennifer Kohl, Global Program Manager, Google Developer Groups

Irem presenting at a Google Developer Group event

We recently caught up with Irem Komurcu, a TensorFlow developer and researcher at Istanbul Technical University in Turkey. Irem has been a long-serving member of Google Developer Groups (GDG) Düzce and also serves as a Women Techmakers (WTM) ambassador. Her work with TensorFlow has received several accolades, including being named a Hamdi Ulukaya Girişimi fellow. As one one of twenty-four young entrepreneurs selected, she was flown to New York City last year to learn more about business and receive professional development.

With all this experience to share, we wanted you to hear how she approaches pursuing a career in tech, hones her TensorFlow skills with the GDG community, and thinks about how upcoming programmers can best position themselves for success. Check out the full interview below for more.

What inspired you to pursue a career in technology?

I first became interested in tech when I was in high school and went on to study computer engineering. At university, I had an eye-opening experience when I traveled from Turkey to the Google Developer Day event in India. It was here where I observed various code languages, products, and projects that were new to me.

In particular, I saw TensorFlow in action for the first time. Watching the powerful machine learning tool truly sparked my interest in deep learning and project development.

Can you describe your work with TensorFlow and Machine Learning?

I have studied many different aspects of Tensorflow and ML. My first work was on voice recognition and deep learning. However, I am now working as a computer vision researcher conducting various segmentation, object detection, and classification processes with Tensorflow. In my free time, I write various articles about best practices and strategies to leverage TensorFlow in ML.

What has been a useful learning resource you have used in your career?

I kicked off my studies on deep learning on tensorflow.org. It’s a basic first step, but a powerful one. There were so many blogs, codes, examples, and tutorials for me to dive into. Both the Google Developer Group and TensorFlow communities also offered chances to bounce questions and ideas off other developers as I learned.

Between these technical resources and the person-to-person support, I was lucky to start working with the GDG community while also taking the first steps of my career. There were so many opportunities to meet people and grow all around.

What is your favorite part of the Google Developer Group community?

I love being in a large community with technology-oriented people. GDG is a network of professionals who support each other, and that enables people to develop. I am continuously sharing my knowledge with other programmers as they simultaneously mentor me. The chance for us to collaborate together is truly fulfilling.

What is unique about being a developer in your country/region?

The number of women supported in science, technology, engineering, and mathematics (STEM) is low in Turkey. To address this, I partner with Women Techmakers (WTM) to give educational talks on TensorFlow and machine learning to women who want to learn how to code in my country. So many women are interested in ML, but just need a friendly, familiar face to help them get started. With WTM, I’ve already given over 30 talks to women in STEM.

What advice would you give to someone who is trying to grow their career as a developer?

Keep researching new things. Read everything you can get your eyes on. Technology has been developing rapidly, and it is necessary to make sure your mind can keep up with the pace. That’s why I recommend communities like GDG that help make sure you’re up to date on the newest trends and learnings.

MediaPipe 3D Face Transform

Posted by Kanstantsin Sokal, Software Engineer, MediaPipe team

Earlier this year, the MediaPipe Team released the Face Mesh solution, which estimates the approximate 3D face shape via 468 landmarks in real-time on mobile devices. In this blog, we introduce a new face transform estimation module that establishes a researcher- and developer-friendly semantic API useful for determining the 3D face pose and attaching virtual objects (like glasses, hats or masks) to a face.

The new module establishes a metric 3D space and uses the landmark screen positions to estimate common 3D face primitives, including a face pose transformation matrix and a triangular face mesh. Under the hood, a lightweight statistical analysis method called Procrustes Analysis is employed to drive a robust, performant and portable logic. The analysis runs on CPU and has a minimal speed/memory footprint on top of the original Face Mesh solution.

Figure 1: An example of virtual mask and glasses effects, based on the MediaPipe Face Mesh solution.

Introduction

The MediaPipe Face Landmark Model performs a single-camera face landmark detection in the screen coordinate space: the X- and Y- coordinates are normalized screen coordinates, while the Z coordinate is relative and is scaled as the X coordinate under the weak perspective projection camera model. While this format is well-suited for some applications, it does not directly enable crucial features like aligning a virtual 3D object with a detected face.

The newly introduced module moves away from the screen coordinate space towards a metric 3D space and provides the necessary primitives to handle a detected face as a regular 3D object. By design, you’ll be able to use a perspective camera to project the final 3D scene back into the screen coordinate space with a guarantee that the face landmark positions are not changed.

Metric 3D Space

The Metric 3D space established within the new module is a right-handed orthonormal metric 3D coordinate space. Within the space, there is a virtual perspective camera located at the space origin and pointed in the negative direction of the Z-axis. It is assumed that the input camera frames are observed by exactly this virtual camera and therefore its parameters are later used to convert the screen landmark coordinates back into the Metric 3D space. The virtual camera parameters can be set freely, however for better results it is advised to set them as close to the real physical camera parameters as possible.

Canonical Face Model

The Canonical Face Model is a static 3D model of a human face, which follows the 3D face landmark topology of the MediaPipe Face Landmark Model. The model bears two important functions:

Defines metric units: the scale of the canonical face model defines the metric units of the Metric 3D space. A metric unit used by the default canonical face model is a centimeter;
Bridges static and runtime spaces: the face pose transformation matrix is – in fact – a linear map from the canonical face model into the runtime face landmark set estimated on each frame. This way, virtual 3D assets modeled around the canonical face model can be aligned with a tracked face by applying the face pose transformation matrix to them.

Face Transform Estimation

The face transform estimation pipeline is a key component, responsible for estimating face transform data within the Metric 3D space. On each frame, the following steps are executed in the given order:

Face landmark screen coordinates are converted into the Metric 3D space coordinates;
Face pose transformation matrix is estimated as a rigid linear mapping from the canonical face metric landmark set into the runtime face metric landmark set in a way that minimizes a difference between the two;
A face mesh is created using the runtime face metric landmarks as the vertex positions (XYZ), while both the vertex texture coordinates (UV) and the triangular topology are inherited from the canonical face model.

Effect Renderer

The Effect Renderer is a component, which serves as a working example of a face effect renderer. It targets the OpenGL ES 2.0 API to enable a real-time performance on mobile devices and supports the following rendering modes:

3D object rendering mode: a virtual object is aligned with a detected face to emulate an object attached to the face (example: glasses);
Face mesh rendering mode: a texture is stretched on top of the face mesh surface to emulate a face painting technique.

In both rendering modes, the face mesh is first rendered as an occluder straight into the depth buffer. This step helps to create a more believable effect via hiding invisible elements behind the face surface.

Figure 3: An example of face effects rendered by the Face Effect Renderer.

Using Face Transform Module

The face transform estimation module is available as a part of the MediaPipe Face Mesh solution. It comes with face effect application examples, available as graphs and mobile apps on Android or iOS. If you wish to go beyond examples, the module contains generic calculators and subgraphs – those can be flexibly applied to solve specific use cases in any MediaPipe graph.

Doubling down on the edge with Coral’s new accelerator

Posted by The Coral Team

Moving into the fall, the Coral platform continues to grow with the release of the M.2 Accelerator with Dual Edge TPU. Its first application is in Google’s Series One room kits where it helps to remove interruptions and makes the audio clearer for better video meetings. To help even more folks build products with Coral intelligence, we’re dropping the prices on several of our products. And for those folks that are looking to level up their at home video production, we’re sharing a demo of a pose based AI director to make multi-camera video easier to make.

Coral M.2 Accelerator with Dual Edge TPU

The newest addition to our product family brings two Edge TPU co-processors to systems in an M.2 E-key form factor. While the design requires a dual bus PCIe M.2 slot, it brings enhanced ML performance (8 TOPS) to tasks such as running two models in parallel or pipelining one large model across both Edge TPUs.

The ability to scale across multiple edge accelerators isn’t limited to only two Edge TPUs. As edge computing expands to local data centers, cell towers, and gateways, multi-Edge TPU configurations will be required to help process increasingly sophisticated ML models. Coral allows the use of a single toolchain to create models for one or more Edge TPUs that can address many different future configurations.

A great example of how the Coral M.2 Accelerator with Dual Edge TPU is being used is in the Series One meeting room kits for Google Meet.

The new Series One room kits for Google Meet run smarter with Coral intelligence

Google’s new Series One room kits use our Coral M.2 Accelerator with Dual Edge TPU to bring enhanced audio clarity to video meetings. TrueVoice®, a multi-channel noise cancellation technology, minimizes distractions to ensure every voice is heard with up to 44 channels of echo and noise cancellation, making distracting sounds like snacking or typing on a keyboard a concern of the past.

Enabling the clearest possible communication in challenging environments was the target for the Google Meet hardware team. The consideration of what makes a challenging environment was not limited to unusually noisy environments, such as lunchrooms doubling as conference rooms. Any conference room can present challenging acoustics that make it difficult for all participants to be heard.

The secret to clarity without expensive and cumbersome equipment is to use virtual audio channels and AI driven sound isolation. Read more about how Coral was used to enhance and future-proof the innovative design.

Expanding the AI edge

Earlier this year, we reduced the prices of our prototyping devices and sensors. We are excited to share further price drops on more of our products. Our System-on-Module is now available for $99.99, and our Mini PCIe Accelerator, M.2 Accelerator A+E Key, and M.2 Accelerator B+M key are now available at $24.99. We hope this lower price will make our edge AI more accessible to more creative minds around the world. Later, this month our SoM offering will also expand to include 2 and 4GB RAM options.

Multi-cam with AI

As we expand our platform and product family, we continue to keep new edge AI use cases in mind. We are continually inspired by our developer community’s experimentation and implementations. When recently faced with the challenges of multicam video production from home, Markku Lepistö, Solutions Architect at Google Cloud, created this real-time pose-based multicam tool he so aptly dubbed, AI Director.

We love seeing such unique implementations of on-device ML and invite you to share your own projects and feedback at [email protected].

Instant Motion Tracking with MediaPipe

Posted by Vikram Sharma, Software Engineering Intern; Jianing Wei, Staff Software Engineer; Tyler Mullen, Senior Software Engineer

Augmented Reality (AR) technology creates fun, engaging, and immersive user experiences. The ability to perform AR tracking across devices and platforms, without initialization, remains important for powering AR applications at scale.

Today, we are excited to release the Instant Motion Tracking solution in MediaPipe. It is built upon the MediaPipe Box Tracking solution we released previously. With Instant Motion Tracking, you can easily place fun virtual 2D and 3D content on static or moving surfaces, allowing them to seamlessly interact with the real world. This technology also powered MotionStills AR. Along with the library, we are releasing an open source Android application to showcase its capabilities. In this application, a user simply taps the camera viewfinder in order to place virtual 3D objects and GIF animations, augmenting the real-world environment.

Instant Motion Tracking in MediaPipe

Instant Motion Tracking

The Instant Motion Tracking solution provides the capability to seamlessly place virtual content on static or motion surfaces in the real world. To achieve that, we provide the six degrees of freedom tracking with relative scale in the form of rotation and translation matrices. This tracking information is then used in the rendering system to overlay virtual content on camera streams to create immersive AR experiences.

The core concept behind Instant Motion Tracking is to decouple the camera’s translation and rotation estimation, treating them instead as independent optimization problems. This approach enables AR tracking across devices and platforms without initialization or calibration. We do this by first finding the 3D camera translation using only the visual signals from the camera. This involves estimating the target region’s apparent 2D translation and relative scale across frames. The process can be illustrated with a simple pinhole camera model, relating translation and scale of an object in the image plane to the final 3D translation.

By finding the change in relative size of our tracked region from view position V1 to V2, we can estimate the relative change in distance from the camera.

Next, we obtain the device’s 3D rotation from its built-in IMU (Inertial Measurement Unit) sensor. By combining this translation and rotation data, we can track a target region with six degrees of freedom at relative scale. This information allows for the placement of virtual content on any system with a camera and IMU functionality, and is calibration free. For more details on Instant Motion Tracking, please refer to our paper.

A MediaPipe Pipeline for Instant Motion Tracking

A diagram of Instant Motion Tracking pipeline is shown below, consisting of four major components: a Sticker Manager module, a Region Tracking module, a Matrices Manager module, and lastly a Rendering System. Each of the components consists of MediaPipe calculators or subgraphs.

Diagram of Instant Motion Tracking Pipeline

The Sticker Manager accepts sticker data from the application and produces initial anchors (tracked region information) based on user taps, and user gesture controls for every sticker object. Initial anchors are then sent to our Region Tracking module to generate tracked anchors. The Matrices Manager combines this data with our device’s rotation matrix to produce six degrees-of-freedom poses as model matrices. After integrating any user-specified transforms like asset scaling, our final poses are forwarded to the Rendering System to render all virtual objects overlaid on the camera frame to produce the output AR frame.

Using the Instant Motion Tracking Solution

The Instant Motion Tracking solution is easy to use by leveraging the MediaPipe cross-platform framework. With camera frames, device rotation matrix, and anchor positions (screen coordinates) as input, the MediaPipe graph produces AR renderings for each frame, providing engaging experiences. If you wish to integrate this Instant Motion Tracking library with your system or application, please visit our documentation to build your own AR experiences on any device with IMU functionality and a camera sensor.

Augmenting The World with 3D Stickers and GIFs

Instant Motion Tracking solution allows bringing both 3D stickers and GIF animations into Augmented Reality experiences. GIFs are rendered on flat 3D billboards placed in the world, introducing fun and immersive experiences with animated content blended into the real environment.Try it for yourself!

Demonstration of GIF placement in 3D

MediaPipe Instant Motion Tracking is already helping PixelShift.AI, a startup applying cutting-edge vision technologies to facilitate video content creation, to track virtual characters seamlessly in the view-finder for a realistic experience. Building upon Instant Motion Tracking’s high-quality pose estimation, PixelShift.AI enables VTubers to create mixed reality experiences with web technologies. The product is going to be released to the broader VTuber community later this year.

Guidance to developers affected by our effort to block less secure browsers and applications

Posted by Lillan Marie Agerup, Product Manager

We are always working to improve security protections of Google accounts. Our security systems automatically detect, alert and help protect our users against a range of security threats. One form of phishing, known as “man-in-the-middle”, is hard to detect when an embedded browser framework (e.g., Chromium Embedded Framework – CEF) or another automation platform is being used for authentication. MITM presents an authentication flow on these platforms and intercepts the communications between a user and Google to gather the user’s credentials (including the second factor in some cases) and sign in. To protect our users from these types of attacks Google Account sign-ins from all embedded frameworks will be blocked starting on January 4, 2021. This block affects CEF-based apps and other non-supported browsers.

To minimize the disruption of service to our partners, we are providing this information to help developers set up OAuth 2.0 flows in supported user-agents. The information in this document outlines the following:

How to enable sign-in on your embedded framework-based apps using browser-based OAuth 2.0 flows.
How to test for compatibility.

Apps that use embedded frameworks

If you’re an app developer and use CEF or other clients for authorization on devices, use browser-based OAuth 2.0 flows. Alternatively, you can use a compatible full native browser for sign-in.

For limited-input device applications, such as applications that do not have access to a browser or have limited input capabilities, use limited-input device OAuth 2.0 flows.

Browsers

Modern browsers with security updates will continue to be supported.

Browser standards

The browser must have JavaScript enabled. For more details, see our previous blog post.

The browser must not proxy or alter the network communication. Your browser must not do any of the following:

Server-side rendering
HTTPS proxy
Replay requests
Rewrite HTTP headers

The browser must have a reasonably complete implementation of web standards and browser features. You must confirm that your browser does not contain any of the following:

Headless browsers
Node.js
Text-based browsers

The browser must identify itself clearly in the User-Agent. The browser must not try to impersonate another browser like Chrome or Firefox.

The browser must not provide automation features. This includes scripts that automate keystrokes or clicks, especially to perform automatic sign-ins. We do not allow sign-in from browsers based on frameworks like CEF or Embedded Internet Explorer.

Test for compatibility

If you’re a developer that currently uses CEF for sign-in, be aware that support for this type of authentication ends on January 4, 2021. To verify whether you’ll be affected by the change, test your application for compatibility. To test your application, add a specific HTTP header and value to disable the allowlist. The following steps explain how to disable the allowlist:

Go to where you send requests to accounts.google.com.
Add Google-Accounts-Check-OAuth-Login:true to your HTTP request headers.

The following example details how to disable the allowlist in CEF.

Note: You can add your custom headers in CefRequestHandler#OnBeforeResourceLoad.

    CefRequest::HeaderMap hdrMap;
    request->GetHeaderMap(hdrMap);
    hdrMap.insert(std::make_pair("Google-Accounts-Check-OAuth-Login", "true"));

To test manually in Chrome, use ModHeader to set the header. The header enables the changes for that particular request.

Setting the header using ModHeader

Helping our communities stay safe, together

As mandatory isolation measures begin to relax, compliance with safe social distancing protocol has become a topic of primary concern for experts across the globe. Businesses and individuals have been stepping up to find ways to use technology to help reduce the risk and spread. Many efforts are employing the benefits of edge AI—here are a few early stage examples that have inspired us.

In Belgium, engineers at Edgise recently used Coral to develop an occupancy monitor to aid businesses in managing capacity. With the privacy preserving properties of edge AI, businesses can anonymously count how many customers enter and exit a space, signaling when the area is too full.

A research group at the Sathyabama Institute of Science and Technology in India are using Coral to develop a wearable device to serve as a COVID-19 cough counter and health monitor, allowing medical professionals to better care for low risk patients in an outpatient capacity. Coral’s Edge TPU enables biometric data to be processed efficiently, without draining the limited power resources available in wearable devices.

All across the US, hospitals are seeking solutions to ensure adherence to hygiene policy amongst hospital staff. In one example, a device incorporates the compact, affordable and offline benefits of the Coral modules to aid in handwashing practices at numerous stations throughout a facility.

And around the world, members of the PyImageSearch community are exploring how to train a COVID-19: Face Mask Detector model using TensorFlow that can be used to identify whether people are wearing a mask. Open source frameworks can empower anyone to develop solutions, and with Coral components we can help bring those benefits to everyone.

Eliciting a global response

In an effort to rally greater community involvement, Coral has joined The United Nations Development Programme and Hackster.io, as a sponsor of the COVID-19 Detect and Protect Challenge. The initiative calls on developers to build affordable and reproducible solutions that support response efforts in developing countries. All ideas are welcome—whether they use ML or not—and we encourage you to participate.

To make edge ML capabilities even easier to integrate, we’re also announcing a price reduction for the Coral products widely used for experimentation and prototyping. Our Dev Board will now be offered at $129.99, the USB Accelerator at $59.99, the Camera Module at $19.99, and the Enviro Board at $14.99. Additionally, we are introducing the USB Accelerator into 10 new markets: Ghana, Thailand, Singapore, Oman, Philippines, Indonesia, Kenya, Malaysia, Israel, and Vietnam. For more details, visit Coral.ai/products.

We’re excited to see the solutions developers will bring forward with Coral. And as always, please keep sending us feedback at [email protected]

Alfred Camera: Smart camera features using MediaPipe

Guest post by the Engineering team at Alfred Camera

Please note that the information, uses, and applications expressed in the below post are solely those of our guest author, Alfred Camera.

In this article, we’d like to give you a short overview of Alfred Camera and our experience of using MediaPipe to transform our moving object feature, and how MediaPipe has helped to get things easier to achieve our goals.

What is Alfred Camera?

Fig.1 Alfred Camera Logo

Alfred Camera is a smart home app for both Android and iOS devices, with over 15 million downloads worldwide. By downloading the app, users are able to turn their spare phones into security cameras and monitors directly, which allows them to watch their homes, shops, pets anytime. The mission of Alfred Camera is to provide affordable home security so that everyone can find peace of mind in this busy world.

The Alfred Camera team is composed of professionals in various fields, including an engineering team with several machine learning and computer vision experts. Our aim is to integrate AI technology into devices that are accessible to everyone.

Machine Learning in Alfred Camera

Alfred Camera currently has a feature called Moving Object Detection, which continuously uses the device’s camera to monitor a target scene. Once it identifies a moving object in the area, the app will begin recording the video and send notifications to the device owner. The machine learning models for detection are hand-crafted and trained by our team using TensorFlow, and run on TensorFlow Lite with good performance even on mid-tier devices. This is important because the app is leveraging old phones and we’d like the feature to reach as many users as possible.

The Challenges

We had started building our AI features at Alfred Camera since 2017. In order to have a solid foundation to support our AI feature requirements for the coming years, we decided to rebuild our real-time video analysis pipeline. At the beginning of the project, the goals were to create a new pipeline which should be 1) modular enough so we could swap core algorithms easily with minimal changes in other parts of the pipeline, 2) having GPU acceleration designed in place, 3) cross-platform as much as possible so there’s no need to create/maintain separate implementations for different platforms. Based on the goals, we had surveyed several open source projects that had the potential but we ended up using none of them as they either fell short on the features or were not providing the readiness/stabilities that we were looking for.

We started a small team to prototype on those goals first for the Android platform. What came later were some tough challenges way above what we originally anticipated. We ran into several major design changes as some key design basics were overlooked. We needed to implement some utilities to do things that sounded trivial but required significant effort to make it right and fast. Dealing with asynchronous processing also led us into a bunch of timing issues, which took the team quite some effort to address. Not to mention debugging on real devices was extremely inefficient and painful.

Things didn’t just stop here. Our product is also on iOS and we had to tackle these challenges once again. Moreover, discrepancies in the behavior between the platform-specific implementations introduced additional issues that we needed to resolve.

Even though we finally managed to get the implementations to the confidence level we wanted, that was not a very pleasant experience and we have never stopped thinking if there is a better option.

MediaPipe – A Game Changer

Google open sourced MediaPipe project in June 2019 and it immediately caught our attention. We were surprised by how it is perfectly aligned with the previous goals we set, and has functionalities that could not have been developed with the amount of engineering resources we had as a small company.

We immediately decided to start an evaluation project by building a new product feature directly using MediaPipe to see if it could live up to all the promises.

Migrating to MediaPipe

To start the evaluation, we decided to migrate our existing moving object feature to see what exactly MediaPipe can do.

Our current Moving Object Detection pipeline consists of the following main components:

(Moving) Object Detection Model
As explained earlier, a TensorFlow Lite model trained by our team, tailored to run on mid-tier devices.
Low-light Detection and Low-light Filter
Calculate the average luminance of the scene, and based on the result conditionally process the incoming frames to intensify the brightness of the pixels to let our users see things in the dark. We are also controlling whether we should run the detection or not as the moving object detection model does not work properly when the frame has been processed by the filter.
Motion Detection
Sending frames through Moving Object Detection still consumes a significant amount of power even with a small model like the one we created. Running inferences continuously does not seem to be a good idea as most of the time there may not be any moving object in front of the camera. We decided to implement a gating mechanism where the frames are only being sent to the Moving Object Detection model based on the movements detected from the scene. The detection is done mainly by calculating the differences between two frames with some additional tricks that take the movements detected in a few frames before into consideration.
Area of Interest
This is a mechanism to let users manually mask out the area where they do not want the camera to see. It can also be done automatically based on regional luminance that can be generated by the aforementioned low-light detection component.

Our current implementation has taken GPU into consideration as much as we can. A series of shaders are created to perform the tasks above and the pipeline is designed to avoid moving pixels between CPU/GPU frequently to eliminate the potential performance hits.

The pipeline involves multiple ML models that are conditionally executed, mixed CPU/GPU processing, etc. All the challenges here make it a perfect showcase for how MediaPipe could help develop a complicated pipeline.

Playing with MediaPipe

MediaPipe provides a lot of code samples for any developer to bootstrap with. We took the Object Detection on Android sample that comes with the project to start with because of the similarity with the back-end part of our pipeline. It did take us sometimes to fully understand the design concepts of MediaPipe and all the tools associated. But with the complete documentation and the great responsiveness from the MediaPipe team, we got up to speed soon to do most of the things we wanted.

That being said, there were a few challenges we needed to overcome on the road to full migration. Our original pipeline of Moving Object Detection takes the input frame asynchronously, but MediaPipe has timestamp bound limitations such that we cannot just show the result in an allochronic way. Meanwhile, we need to gather data through JNI in a specific data format. We came up with a workaround that conquered all the issues under the circumstances, which will be mentioned later.

After wrapping our models and the processing logics into calculators and wired them up, we have successfully transformed our existing implementation and created our first MediaPipe Moving Object Detection pipeline like the figure below, running on Android devices:

Fig.2 Moving Object Detection Graph

We do not block the video frame in the main calculation loop, and set the detection result as an input stream to show the annotation on the screen. The whole graph is designed as a multi-functioned process, the left chunk is the debug annotation and video frame output module, and the rest of the calculation occurs in the rest of the graph, e.g., low light detection, motion triggered detection, cropping of the area of interest and the detection process. In this way, the graph process will naturally separate into real-time display and asynchronous calculation.

As a result, we are able to complete a full processing for detection in under 40ms on a device with Snapdragon 660 chipset. MediaPipe’s tight integration with TensorFlow Lite provides us the flexibility to get even more performance gain by leveraging whatever acceleration techniques available (GPU or DSP) on the device.

The following figure shows the current implementation working in action:

Fig.3 Moving Object Detection running in Alfred Camera

After getting things to run on Android, Desktop GPU (OpenGL-ES) emulation was our next target to evaluate. We are already using OpenGL-ES shaders for some computer vision operations in our pipeline. Having the capability to develop the algorithm on desktop, seeing it work in action before deployment onto mobile platforms is a huge benefit to us. The feature was not ready at the time when the project was first released, but MediaPipe team had soon added Desktop GPU emulation support for Linux in follow-up releases to make this possible. We have used the capability to detect and fix some issues in the graphs we created even before we put things on the mobile devices. Although it currently only works on Linux, it is still a big leap forward for us.

Testing the algorithms and making sure they behave as expected is also a challenge for a camera application. MediaPipe helps us simplify this by using pre-recorded MP4 files as input so we could verify the behavior simply by replaying the files. There is also built-in profiling support that makes it easy for us to locate potential performance bottlenecks.

MediaPipe – Exactly What We Were Looking For

The result of the evaluation and the feedback from our engineering team were very positive and promising:

We are able to design/verify the algorithm and complete core implementations directly on the desktop emulation environment, and then migrate to the target platforms with minimum efforts. As a result, complexities of debugging on real devices are greatly reduced.
MediaPipe’s modular design of graphs/calculators enables us to better split up the development into different engineers/teams, try out new pipeline design easily by rewiring the graph, and test the building blocks independently to ensure quality before we put things together.
MediaPipe’s cross-platform design maximizes the reusability and minimizes fragmentation of the implementations we created. Not only are the efforts required to support a new platform greatly reduced, but we are also less worried about the behavior discrepancies on different platforms due to different interpretations of the spec from platform engineers.
Built-in graphics utilities and profiling support saved us a lot of time creating those common facilities and making them right, and we could be more focused on the key designs.
Tight integration with TensorFlow Lite really saves lots of effort for a company like us that heavily depends on TensorFlow, and it still gives us the flexibility to easily interface with other solutions.

With just a few weeks working with MediaPipe, it has shown strong capabilities to fundamentally transform how we develop our products. Without MediaPipe we could have spent months creating the same features without the same level of performance.

Summary

Alfred Camera is designed to bring home security with AI to everyone, and MediaPipe has significantly made achieving that goal easier for our team. From Moving Object Detection to future AI-powered features, we are focusing on transforming a basic security camera use case into a smart housekeeper that can help provide even more context that our users care about. With the support of MediaPipe, we have been able to accelerate our development process and bring the features to the market at an unprecedented speed. Our team is really excited about how MediaPipe could help us progress and discover new possibilities, and is looking forward to the enhancements that are yet to come to the project.

ExpressRoute Global Reach: Building your own cloud-based global backbone

Connectivity has gone through a fundamental shift as more workloads and services have moved to the Cloud. Traditional enterprise Wide Area Networks (WAN) have been fixed in nature, without the ability to dynamically scale to meet modern customer demands. For customers seeking to increasingly apply a cloud-first approach as the basis for their app and networking strategy, hybrid cloud enables applications and services to be deployed cross-premises as a fully connected and seamless architecture. The connectivity across premises is moving to utilize a more cloud-first model, with services offered by global hyper-scale networks.

Microsoft global network

Microsoft operates one of the  largest networks on the globe  spanning over 130,000 miles of terrestrial and subsea fiber cable systems across 6 continents. Besides Azure, the global network powers all our cloud services, including Bing, Office 365 and Xbox. The network carries more than 30 billion packets per second at any one time and is accessible for peering, private connectivity and application content delivery through our more than 160 global network PoPs. Microsoft continuously add new network PoPs to optimize the experience for our customers accessing Microsoft services.

The global network is built and operated using intelligent software-defined traffic engineering technologies, that allow Microsoft to dynamically select optimal paths and route around network faults and congestion scenarios in near real-time. The network has multiple redundant paths to ensure maximum uptime and reliability when powering mission-critical workloads for our customers.

ExpressRoute overview

Azure ExpressRoute provides enterprises with a service that bypasses the Internet to securely and privately connect to Azure and to create their own global network. A common scenario is for enterprises to use ExpressRoute to access their Azure virtual networks (VNets) containing their own private IP addresses. This allows Azure to become a seamless hybrid extension of their on-premises networks. Another scenario includes using ExpressRoute to access public services over a private connection such as Azure Storage or Azure SQL. Traffic for ExpressRoute enters the Microsoft network at our networking Points of Presence (or PoPs) strategically distributed across the world, which are hosted in carrier-neutral facilities to provide customers options when picking a carrier or Telco partner.

ExpressRoute provides three different SKUs of ExpressRoute circuits:

ExpressRoute Local: Available at ExpressRoute sites physically close to an Azure region and can be used only to access the local Azure region. Because the traffic stays in the regional network and does not traverse the global network, the ExpressRoute Local traffic has no egress charge.
ExpressRoute Standard: Provides connectivity to any Azure region with in the same geopolitical region as the ExpressRoute site from London to West Europe, for example.
ExpressRoute Premium: Provides connectivity to any Azure region within the cloud environment. For example, an ExpressRoute Premium circuit at the New Zealand site can access Azure regions in Australia or other geographies from Europe or North America.

In addition to using the more than 200 ExpressRoute partners to connect for ExpressRoute, enterprises can directly connect to ExpressRoute routers with the ExpressRoute Direct option, at either 10G or 100G physical interfaces. Within ExpressRoute Direct, enterprises can divide up this physical port into multiple ExpressRoute circuits to serve different business units and use cases.

Many customers want to take further advantage of their existing architecture and ExpressRoute connections to provide connectivity between their on-premises sites or data centers. Enabling site-to-site connectivity across our global network is now very easy. When Azure introduced ExpressRoute Global Reach, as the first in public cloud, we provided a sleek and simple way to take full advantage of our global backbone assets.

ExpressRoute Global Reach

With ExpressRoute Global Reach, we are democratizing connectivity, allowing enterprises to build cloud based virtual global backbones by using ExpressRoute and Microsoft’s global network. ExpressRoute Global Reach enables connectivity from on-premises to on-premises fully routed privately within the Microsoft global backbone. This capability can be a backup to existing network infrastructure, or it can be the primary means to serve enterprise Wide Area Network (WAN) needs. Microsoft takes care of redundancy, the larger global infrastructure investments, and the scale out requirements, allowing customers to focus on their core mission. 

Consider Contoso, a multi-national company headquartered in Dallas, Texas with global offices in London and Tokyo. These three main locations also serve as major connectivity hubs for branch offices and on-premises datacenters. Utilizing a local last-mile carrier, Contoso invests in redundant paths to meet at the ExpressRoute sites in these same locations. After establishing the physical connectivity, Contoso stands up their ExpressRoute connectivity through a local provider or via ExpressRoute Direct and starts advertising routes via the industry standard, Border Gateway Protocol (BGP). Contoso can now connect all these sites together and opt to enable Global Reach, which will take the on-premises routes and advertise them to the peered circuit in the remote locations, enabling cross-premises connectivity. Contoso has now created a cloud-based Wide Area Network and all within minutes. Effectively end-to-end global connectivity without long-haul investments and fixed contracts.

Modernizing the network and applying the cloud-first model help customers scale with their needs, while at the same time take full advantage and build onto their existing cloud infrastructure. As on-premises sites and branches emerge or change, global connectivity should be as easy as a click of a button. ExpressRoute Global Reach enables companies to provide best in class connectivity on one of the most comprehensive software-defined networks on the planet.

ExpressRoute Global Reach is generally available in these locations, including Azure US Government.

Azure HBv2 Virtual Machines eclipse 80,000 cores for MPI HPC

HPC-optimized virtual machines now available

Azure HBv2-series Virtual Machines (VMs) are now generally available in the South Central US region. HBv2 VMs will also be available in West Europe, East US, West US 2, North Central US, Japan East soon.

HBv2 VMs deliver supercomputer-class performance, message passing interface (MPI) scalability, and cost efficiency for a variety of real-world high performance computing (HPC) workloads, such as CFD, explicit finite element analysis, seismic processing, reservoir modeling, rendering, and weather simulation.

Azure HBv2 VMs are the first in the public cloud to feature 200 gigabit per second HDR InfiniBand from Mellanox. HDR InfiniBand on Azure delivers latencies as low as 1.5 microseconds, more than 200 million messages per second per VM, and advanced in-network computing engines like hardware offload of MPI collectives and adaptive routing for higher performance on the largest scaling HPC workloads. HBv2 VMs use standard Mellanox OFED drivers that support all RDMA verbs and MPI variants.

Each HBv2 VM features 120 AMD EPYC™ 7002-series CPU cores with clock frequencies up to 3.3 GHz, 480 GB of RAM, 480 MB of L3 cache, and no simultaneous multithreading (SMT). HBv2 VMs provide up to 340 GB/sec of memory bandwidth, which is 45-50 percent more than comparable x86 alternatives and three times faster than what most HPC customers have in their datacenters today. A HBv2 virtual machine is capable of up to 4 double-precision teraFLOPS, and up to 8 single-precision teraFLOPS.

One and three year Reserved Instance, Pay-As-You-Go, and Spot Pricing for HBv2 VMs is available now for both Linux and Windows deployments. For information about five-year Reserved Instances, contact your Azure representative.

Disruptive speed for critical weather forecasting

Numerical Weather Prediction (NWP) and simulation has long been one of the most beneficial use cases for HPC. Using NWP techniques, scientists can better understand and predict the behavior of our atmosphere, which in turn drives advances in everything from coordinating airline traffic, shipping of goods around the globe, ensuring business continuity, and critical disaster preparedness from the most adverse weather. Microsoft recognizes the criticality of this field is to science and society, which is why Azure shares US hourly weather forecast data produced by the Global Forecast System (GFS) from the National Oceanic and Atmospheric Administration (NOAA) as part of the Azure Open Datasets initiative.

Cormac Garvey, a member of the HPC Azure Global team, has extensive experience supporting weather simulation teams on the world’s most powerful supercomputers. Today, he’s published a guide to running the widely-used Weather Research and Forecasting (WRF) Version 4 simulation suite on HBv2 VMs.

Cormac used a 371M grid point simulation of Hurricane Maria, a Category 5 storm that struck the Caribbean in 2017, with a resolution of 1 kilometer. This model was chosen not only as a rigorous benchmark of HBv2 VMs but also because the fast and accurate simulation of dangerous storms is one of the most vital functions of the meteorology community.

Figure 1: WRF Speedup from 1 to 672 Azure HBv2 VMs.

Nodes (VMs)	Parallel Processes	Average Time(s) per Time Step	Scaling Efficiency	Speedup (VM-based)
1	120	18.51	100 percent	1.00
2	240	8.9	104 percent	2.08
4	480	4.37	106 percent	4.24
8	960	2.21	105 percent	8.38
16	1,920	1.16	100 percent	15.96
32	3,840	0.58	100 percent	31.91
64	7,680	0.31	93 percent	59.71
128	15,360	0.131	110 percent	141.30
256	23,040	0.082	88 percent	225.73
512	46,080	0.0456	79 percent	405.92
640	57,600	0.0393	74 percent	470.99
672	80,640	0.0384	72 percent	482.03

Figure 2: Scaling and configuration data for WRF on Azure HBv2 VMs.

Note: for some scaling points, optimal performance is achieved with 30 MPI ranks and 4 threads per rank, while in others 90 MPI ranks was optimal. All tests were run with OpenMPI 4.0.2.

Azure HBv2 VMs executed the “Maria” simulation with mostly super-linear scalability up to 128 VMs (15,360 parallel processes). Improvements from scaling continue up to the largest scale of 672 VMs (80,640 parallel processes) tested in this exercise, where a 482x speedup over a single VM. At 512 nodes (VMs) we observe a ~2.2x performance increase as compared to a leading supercomputer that debuted among the top 20 fastest machines in 2016.

The gating factor to higher levels of scaling efficiency? The 371M grid point model, even as one of the largest known WRF models, is too small at such extreme levels of parallel processing. This opens the door for leading weather forecasting organizations to leverage Azure to build and operationalize even higher resolution models that higher numerical accuracy and a more realistic understanding of these complex weather phenomena.

Better, safer product design from hyper-realistic CFD

Computational fluid dynamics (CFD) is core to the simulation-driven businesses of many Azure customers. A common request from customers is to “10x” their capabilities while keeping costs as close to constant as possible. Specifically, customers often seek ways to significantly increase the accuracy of their models by simulating it in higher resolution. Given that many customers already solve CFD problems with ~500-1000 parallel processes per job, this is a tall task that implies linear scaling to at least 5,000-10,000 parallel processes. Last year, Azure accomplished one of these objectives when it became the first public cloud to scale a CFD application to more than 10,000 parallel processes. With the launch of HBv2 VMs, Azure’s CFD capabilities are increasing again.

Jon Shelley, also a member of the Azure Global HPC team, worked with Siemens to validate one its largest CFD simulations ever, a 1 billion cell model of a sports car named after the famed 24 Hours of Le Mans race with a 10x higher-resolution mesh than what Azure tested just last year. Jon has published a guide to running Simcenter STAR-CCM+ at large scale on HBv2 VMs.

Figure 3: Simcenter STAR-CCM+ Scaling Efficiency from 1 to 640 Azure HBv2 VMs

Nodes (VMs)	Parallel Processes	Solver Elapsed Time	Scaling Efficiency	Speedup (VM-based)
8	928	337.71	100 percent	1.00
16	1,856	164.79	102.5 percent	2.05
32	3,712	82.07	102.9 percent	4.11
64	7,424	41.02	102.9 percent	8.23
128	14,848	20.94	100.8 percent	16.13
256	29,696	12.02	87.8 percent	28.10
320	37,120	9.57	88.2 percent	35.29
384	44,544	7.117	98.9 percent	47.45
512	59,392	6.417	82.2 percent	52.63
640	57,600	5.03	83.9 percent	67.14

Figure 4: Scaling and configuration data for STAR-CCM+ on Azure HBv2 VMs

Note: A given scaling point may achieve optimal performance with 90, 112, 116, or 120 parallel processes per VM. Plotted data below shows optimal performance figures. All tests were run with HPC-X MPI ver. 2.50.

Once again, Azure HBv2 executed the challenging problem with linear efficiency to more than 15,000 parallel processes across 128 VMs. From there, high scaling efficiency continued, peaking at nearly 99 percent at more than 44,000 parallel processes. At the largest scale of 640 VMs and 57,600 parallel processes, HBv2 delivered 84 percent scaling efficiency. This is among the largest scaling CFD simulations with Simcenter STAR-CCM+ ever performed, and now can be replicated by Azure customers.

Extreme HPC I/O meets cost-efficiency

An increasing scenario on the cloud is on-demand HPC-grade parallel filesystems. The rationale is straight forward; if a customer needs to perform a large quantity of compute, that customer often needs to also move a lot of data into and out of those compute resources. The catch? Simple cost comparisons against traditional on-premises HPC filesystem appliances can be unfavorable, depending on circumstances. With Azure HBv2 VMs, however, NVMeDirect technology can be combined with ultra low-latency RDMA capabilities to deliver on-demand “burst buffer” parallel filesystems at no additional cost beyond the HBv2 VMs already provisioned for compute purposes.

BeeGFS is one such filesystem and has a rapidly growing user base among both entry-level and extreme-scale users. The BeeOND filesystem is even used in production on the novel HPC + AI hybrid supercomputer “Tsubame 3.0.”

Here is a high-level summary of how a sample BeeOND filesystem looks when created across 352 HBv2 VMs, providing 308 terabytes of usable, high-performance namespace.

Figure 5: Overview of example BeeOND filesystem on HBv2 VMs.

Running the widely-used IOR test of parallel filesystems across 352 HBv2 VMs, BeeOND achieved peak read performance of 763 gigabytes per second, and peak write performance of 352 gigabytes per second.

Visit Cormac’s blog post on the Azure Tech Community to learn how to run BeeGFS on RDMA-powered Azure Virtual Machines.

10x-ing the cloud HPC experience

Microsoft Azure is committed to delivering to our customers a world-class HPC experience, and maximum levels of performance, price/performance, and scalability.

“The 2nd Gen AMD EPYC processors provide fantastic core scaling, access to massive memory bandwidth and are the first x86 server processors that support PCIe 4.0; all of these features enable some of the best high-performance computing experiences for the industry,” said Ram Peddibhotla, corporate vice president, Data Center Product Management, AMD. “What Azure has done for HPC in the cloud is amazing; demonstrating that HBv2 VMs and 2nd Gen EPYC processors can deliver supercomputer-class performance, MPI scalability, and cost efficiency for a variety of real-world HPC workloads, while democratizing access to HPC that will help drive the advancement of science and research.”

“200 gigabit HDR InfiniBand delivers high data throughout, extremely low latency, and smart In-Network Computing engines, enabling high performance and scalability for compute and data applications. We are excited to collaborate with Microsoft to bring the InfiniBand advantages into Azure, providing users with leading HPC cloud services” said Gilad Shainer, Senior Vice President of Marketing at Mellanox Technologies. “By taking advantage of InfiniBand RDMA and its MPI acceleration engines, Azure delivers higher performance compared to other cloud options based on Ethernet. We look forward to continuing to work with Microsoft to introduce future generations and capabilities.”

Azure Cost Management + Billing updates – February 2020

Whether you’re a new student, thriving startup, or the largest enterprise, you have financial constraints and you need to know what you’re spending, where, and how to plan for the future. Nobody wants a surprise when it comes to the bill, and this is where Azure Cost Management + Billing comes in.

We’re always looking for ways to learn more about your challenges and how Azure Cost Management + Billing can help you better understand where you’re accruing costs in the cloud, identify and prevent bad spending patterns, and optimize costs to empower you to do more with less. Here are a few of the latest improvements and updates based on your feedback:

Let’s dig into the details.

New Power BI reports for Azure reservations and Azure Hybrid Benefit

Azure Cost Management + Billing offers several ways to report on your cost and usage data. You can start in the portal, download data or schedule an automated export for offline analysis, or even integrate with Cost Management APIs directly. But maybe you just need detailed reporting alongside other business reports. This is where the Power BI comes in. We last talked about the addition of reservation purchases in the Azure Cost Management Power BI connector in October. Building on top of that, the new Azure Cost Management Power BI app offers an extensive set of reports to get you started, including detailed reservation and Azure Hybrid Benefit reports.

The Account overview offers a summary of all usage and purchases as well as your credit balance to help you track monthly expenses. From here, you can dig in to usage costs broken down by subscription, resource group, or service in additional pages. Or, if you simply want to see your prices, take a look at the Price sheet page.

If you’re already using Azure Hybrid Benefit (AHB) or have existing, unused on-prem Windows licenses, check out the Windows Server AHB Usage page. Start by checking how many VMs currently have AHB enabled to determine if you have additional licenses that could help you further lower your costs. If you do have additional licenses, you can also identify eligible VMs based on their core/vCPU count. Apply AHB to your most expensive VMs to maximize your potential savings.

If you’re using Azure reservations or are interested in potential savings you could benefit from if you did, you’ll want to check out the VM RI coverage pages to identify any new opportunities where you can save with new reservations, including the historical usage so you can see why that reservation is recommended. You can drill in to a specific region or instance size flexibility group and more. You can see your past purchases in the RI purchases page and get a breakdown of those costs by region, subscription, or resource group in the RI chargeback page, if you need to do any internal chargeback. And, don’t forget to check out the RI savings page, where you can see how much you’ve saved so far by using Azure reservations.

This is just the first release of a new generation of Power BI reports. Get started with the Azure Cost Management Power BI quickstart today and let us know what you’d like to see next.

Quicker access to help and support

Learning something new can be a challenge; especially when it’s not your primary focus. But given how critical it is to meet your financial goals, getting help and support needs to be front and center. To support this, Cost Management now includes a contextual Help menu to direct you to documentation and support experiences.

Get started with a quickstart tutorial and, when you’re ready to automate that experience or integrate it into your own apps, check out the API reference. If you have any suggestions on how the experience could be improved for you, please don’t hesitate to share your feedback. If you run into an issue or see something that doesn’t make sense, start with Diagnose and solve problems, and if you don’t see a solution, then please do submit a new support request. We’re closely monitoring all feedback and support requests to identify ways the experience could be streamlined for you. Let us know what you’d like to see next.

We need your feedback

As you know, we’re always looking for ways to learn more about your needs and expectations. This month, we’d like to learn more about how you report on and analyze your cloud usage and costs in a brief survey. We’ll use your inputs from this survey to inform ease of use and navigation improvements within Cost Management + Billing experiences. The 15-question survey should take about 10 minutes.

Take the survey.

What’s new in Cost Management Labs

With Cost Management Labs, you get a sneak peek at what’s coming in Azure Cost Management and can engage directly with us to share feedback and help us better understand how you use the service, so we can deliver more tuned and optimized experiences. Here are a few features you can see in Cost Management Labs:

Get started quicker with the cost analysis Home view
Azure Cost Management offers five built-in views to get started with understanding and drilling into your costs. The Home view gives you quick access to those views so you get to what you need faster.
New: More details in the cost by resource view
Drill in to the cost of your resources to break them down by meter. Simply expand the row to see more details or click the link to open and take action on your resources.
New: Explain what “not applicable” means
Break down “not applicable” to explain why specific properties don’t have values within cost analysis.

Of course, that’s not all. Every change in Azure Cost Management is available in Cost Management Labs a week before it’s in the full Azure portal. We’re eager to hear your thoughts and understand what you’d like to see next. What are you waiting for? Try Cost Management Labs today.

Drill in to the costs for your resources

Resources are the fundamental building block in the cloud. Whether you’re using the cloud as infrastructure or componentized microservices, you use resources to piece together your solution and achieve your vision. And how you use these resources ultimately determines what you’re billed for, which breaks down to individual “meters” for each of your resources. Each service tracks a unique set of meters covering time, size, or other generalized unit. The more units you use, the higher the cost.

Today, you can see costs broken down by resource or meter with built-in views, but seeing both together requires additional filtering and grouping to get down to the data you need, which can be tedious. To simplify this, you can now expand each row in the Cost by resource view to see the individual meters that contribute to the cost of that resource.

This additional clarity and transparency should help you better understand the costs you’re accruing for each resource at the lowest level. And if you see a resource that shouldn’t be running, simply click the name to open the resource, where you can stop or delete it to avoid incurring additional cost.

You can see the updated Cost by resource view in Cost Management Labs today, while in preview. Let us know if you have any feedback. We’d love to know what you’d like to see next. This should be available everywhere within the next few weeks.

Understanding why you see “not applicable”

Azure Cost Management + Billing includes all usage, purchases, and refunds for your billing account. Seeing every line item in the full usage and charges file allows you to reconcile your bill at the lowest level, but since each of these records has different properties, aggregating them within cost analysis can result in groups of empty properties. This is when you see “not applicable” today.

Now, in Cost Management Labs, you can see these costs broken down and categorized into separate groups to bring additional clarity and explain what each represents. Here are a few examples:

You may see Other classic resources for any classic resources that don’t include resource group in usage data when grouping by resource or resource group.
If you’re using any services that aren’t deployed to resource groups, like Security Center or Azure DevOps (Visual Studio Online), you will see Other subscription resources when grouping by resource group.
You may recall seeing Untagged costs when grouping by a specific tag. This group is now broken down further into Tags not available and Tags not supported groups. These signify services that don’t include tags in usage data (see How tags are used) and costs that can’t be tagged, like purchases and resources not deployed to resource groups, covered above.
Since purchases aren’t associated with an Azure resource, you might see Other Azure purchases or Other Marketplace purchases when grouping by resource, resource group, or subscription.
You may also see Other Marketplace purchases when grouping by reservation. This represents other purchases, which aren’t associated with a reservation.
If you have a reservation, you may see Unused reservation when viewing amortized costs and grouping by resource, resource group, or subscription. This represents the unused portion of your reservation that isn’t associated with any resources. These costs will only be visible from your billing account or billing profile.

Of course, these are just a few examples. You may see more. When there simply isn’t a value, you’ll see something like No department, as an example, which represents Enterprise Agreement (EA) subscriptions that aren’t grouped into a department.

We hope these changes help you better understand your cost and usage data. You can see this today in Cost Management Labs while in preview. Please check it out and let us know if you have any feedback. This should be available everywhere within the next few weeks.

Upcoming changes to Azure usage data

Many organizations use the full Azure usage and charges to understand what’s being used, identify what charges should be internally billed to which teams, and/or to look for opportunities to optimize costs with Azure reservations and Azure Hybrid Benefit, just to name a few. If you’re doing any analysis or have setup integration based on product details in the usage data, please update your logic for the following services.

The following change will start effective March 1:

Autodesk Arnold Service meter IDs will change.

Also, remember the key-based Enterprise Agreement (EA) billing APIs have been replaced by new Azure Resource Manager APIs. The key-based APIs will still work through the end of your enrollment, but will no longer be available when you renew and transition into Microsoft Customer Agreement. Please plan your migration to the latest version of the UsageDetails API to ease your transition to Microsoft Customer Agreement at your next renewal.
