Announcing GA of Read Replica for Azure PostgreSQL Flexible Server
Introduction
Today, Microsoft announces the general availability (GA) of read replica for Azure Database for PostgreSQL Flexible Server. This GA version of read replica enables customers to create replicas of their databases for read-only workloads. This provides customers with a way to scale out their read workloads and to minimize the overhead on the primary server.
Benefits of Read Replica for Flexible Server
The read replica for Flexible Server provides customers with the following benefits:
* Enhanced scalability – Customers can scale out read workloads to increase performance, while minimizing the overhead on the primary server.
* Improved high availability – Customers can configure a read replica to be used as a failover target in case of a primary server outage.
* Reduced costs – Customers can optimize their costs by using read replicas for read-only workloads.
How to Create Read Replicas for Flexible Server?
Creating read replicas for Flexible Server is easy. Here is a step-by-step guide to help you get started:
1. Login to Azure Portal and select the PostgreSQL server you want to create the read replica for.
