# Add Aurora RDS replicas

Aurora database replica setup is slightly different from [adding an RDS read replica](/docs/automation-platform/overview/aws-services/database/rds-database/add-an-rds-read-replica.md).

## Adding an Aurora read replica

1. [Create an Aurora RDS database](/docs/automation-platform/overview/aws-services/database/rds-database.md).
2. In the DuploCloud Portal, navigate to **Cloud Services** -> **Database**.
3. In the row of the RDS for which you want to add an Aurora read replica, click the ( <img src="/files/OwCtBIhPsyYkJQ1Lne65" alt="" data-size="line"> ) icon, select **RDS Settings**, and then **Add Replica**. The **Add Replica** pane displays.

Follow one of these procedures to complete the serverless and MySQL replicas setup.

### Adding an Aurora Serverless read replica

1. In the **Add Replica** pane, enter a name for the Serverless replica in the Replica Name field.
2. In the **RDS Engine** field, select the **Aurora** RDS Serverless engine you want the replica to use.
3. Specify **Min Capacity (ACUs)** and **Max Capacity (ACUs)**.
4. From the **RDS Instance Size** list box, select the appropriate instance size.
5. Click **Save**. The replica is created with a **Reader** role and displayed in the **RDS** tab.

#### Updating instance sizes for Aurora Serverless read replicas

To modify instance sizes for an existing Aurora Serverless replica:

1. In the DuploCloud Portal, navigate to **Cloud Services** -> **Database** and, in the **RDS** tab, locate the read replica you want to update in the **Name** column.
2. Click the ( <img src="/files/7DagHksotNef8625xoXr" alt="" data-size="line"> ) icon in the **Actions** column and select **Update Instance Size**. The **Update Instance Size** pane displays.<br>

### Adding an Aurora MySQL read replica

1. In the **Add Replica** pane, enter a name for the MySQL replica in the **Replica Name** field.
2. From the **RDS Instance Size** list box, select the appropriate instance size.
3. From the **Availability Zone** list box, select an availability zone
4. Click **Save**. The replica is created with a **Reader** role and displayed in the **RDS** tab.
