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.

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

  • 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
    Sydney, Australia
    ap-southeast-2

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.
