# Step 1: Deploy the primary and replica databases

The setup instructions are based on a [architecture-example](https://docs.sonarsource.com/sonarqube-server/2025.4/server-installation/data-center-edition/on-kubernetes-or-openshift/setting-up-disaster-recovery/architecture-example "mention").

Deploy the primary and replica PostgreSQL databases on Azure as follows:

1. On the Azure Database for PostgreSQL flexible server creation page of your primary database, select your subscription and resource group.
2. In **Server details** > **Compute + storage**, select **Configure server**. A new pane opens.

3. In **Backups**, enable the **Geo-redundancy**.

4. Once the primary database has been deployed, create the replica database. To do so, go to the primary database resource page > **Settings >** **Replication >** **Create replica**. Ensure that you select a different **Availability zone** than for the primary database.

5. Create virtual endpoints: go to **Database Settings** > **Replication** > **Virtual endpoints**.
