This allows you to take advantage of the latest Azure services and features in different regions and to take advantage of cost savings opportunities. Additionally, you can create multiple replicas in different regions for high availability and disaster recovery.
How to Configure Failover Between Regions with Flexible Server
Configuring failover between regions with a Flexible Server is a relatively straightforward process. The following steps outline the process:
* Create a Flexible Server.
* Create replicas in other regions.
* Configure the replicas to read-only access.
* Configure the replicas to synchronize data with the primary server.
* Configure the failover policy.
Conclusion
