Amazon RDS for Oracle Now Supports In-region Read Replicas with Active Data Guard for Read Scalability and Availability
Starting today, Amazon Relational Database Service (RDS) for Oracle supports Read Replicas with Active Data Guard. Amazon RDS for Oracle makes it easy to create the replicas in the same AWS Region as the primary DB instance by fully managing the configuration of Active Data Guard, and maintaining secure network connections between a primary DB instance and its replicas.
The Read Replicas feature is supported for RDS Oracle customers who are using the Bring Your Own License model with Oracle Database Enterprise Edition and have licensed the Active Data Guard Option. This feature allows RDS Oracle customers to offload their read workload from the primary DB Instance, and also supports the scalability of read workloads over a farm of up to five read replicas. The Read Replicas can also render another level of availability by allowing you to promote a given read replica as a new standalone database, in the event of a failure of the primary DB Instance.
A Read Replica is billed as a standard DB Instance and at the same rates. Just like a standard DB instance, the rate per “DB Instance hour” for a read replica is determined by the DB instance class of the read replica.
This feature is supported in all commercial regions where Amazon RDS for Oracle is available, except in the Stockholm and Ningxia regions. To learn more, please visit the In-region Oracle Read Replicas documentation page.
Amazon RDS makes it easy to set up, operate, and scale a relational database in the cloud. See Amazon RDS for Oracle Pricing for up-to-date pricing and regional availability.
