Amazon S3 Multi-Region Access Points routing states

Your Amazon S3 Multi-Region Access Points failover configuration determines the routing status of the AWS Regions that are used with the Multi-Region Access Point. You can configure your Amazon S3 Multi-Region Access Point to be in an active-active state or active-passive state.

• Active-active – In an active-active configuration, all requests are automatically sent to the closest proximity AWS Region in your Multi-Region Access Point. After the Multi-Region Access Point has been configured to be in an active-active state, all Regions can receive traffic. If traffic disruption occurs in an active-active configuration, network traffic will automatically be redirected to one of the active Regions.

• Active-passive – In an active-passive configuration, the active Regions in your Multi-Region Access Point receive traffic and the passive ones do not. If you intend to use S3 failover controls to initiate failover in a disaster situation, set up your Multi-Region Access Points in an active-passive configuration while you're testing and performing disaster-recovery planning.
