Geo-replication

Azure Database for PostgreSQL provides built-in support for geo-replication, allowing you to replicate your databases to a secondary region for high availability and disaster recovery purposes. This means that your data is replicated synchronously or asynchronously to a secondary region, ensuring that you can quickly failover to the secondary region in case of a primary region outage.

To configure geo-replication, follow these steps:

In the Azure portal, navigate to your Azure Database for PostgreSQL resource.
Click on “Geo-replication” in the settings menu.
Select the secondary region where you want to replicate your data.
Choose the replication mode, either synchronous or asynchronous, based on your availability and performance requirements.
Click on “Apply” to initiate the replication process.

By configuring geo-replication, you can ensure that your databases remain highly available and can withstand regional outages, providing business continuity and minimizing downtime.

Automatic failover

Azure Database for PostgreSQL supports automatic failover for high availability. By enabling failover, Azure automatically promotes the secondary database to become the primary in the event of a primary database failure. This ensures that your applications can continue to operate seamlessly without manual intervention, minimizing downtime and preventing data loss.

To enable automatic failover, follow these steps:

In the Azure portal, navigate to your Azure Database for PostgreSQL resource.
Click on “Failover” in the settings menu.
Enable automatic failover by selecting the checkbox.
