Update a Federated Database Instance Region

You can change the AWS region through which your federated database instance requests are routed. By default, Data Federation requests are routed through the region that is closest to your client application. The region that is closest to your application may be different from the regions that house your data stores.

Note

If you change the AWS region through which your federated database instance requests are routed, you must update your federated database instance connection string with the new hostname. This change ensures that your requests are routed through the new region.

Procedure

To change the AWS region through which your federated database instance requests are routed, do the following in the Atlas UI:

Select Data Federation from the left-hand navigation.

Click Ellipses (...) for your federated database instance.

Select Update Region from the dropdown to display the Update Region modal.

Choose the region through which to route your federated database instance requests:

The closest available region to allow Atlas to automatically choose the Data Federation region closest to you.

A specific region to specify the region through which your federated database instance requests must be routed.

You can select from the following regions:

Data Federation Regions	AWS Regions
Virginia, USA	us-east-1
Oregon, USA	us-west-2
Sao Paulo, Brazil	sa-east-1
Ireland	eu-west-1
London, England	eu-west-2
Frankfurt, Germany	eu-central-1
Mumbai, India	ap-south-1
Singapore	ap-southeast-1
Sydney, Australia	ap-southeast-2

Click Save for the changes to take effect.

The federated database hostname in your current federated database instance connection string will continue to work. However, to use the region you selected, you must update the federated database hostname in your federated database instance connection string. To utilize the new region, click the Connect button for your federated database instance and follow the steps in Connect to Your Federated Database Instance.
