Creating, updating, and deleting recovery groups in Route 53 ARC

A recovery group represents your application in Amazon Route 53 Application Recovery Controller. It typically consists of two or more cells that are replicas of each other in terms of resources and functionality, so that you can fail over from one to the other. Each cell includes the Amazon Resource Names (ARNs) for the active resources for one Amazon Region or Availability Zone. The resources might be an Elastic Load Balancing load balancer, an Auto Scaling group, or other resources. A corresponding cell representing another zone or Region has standby resources of the same type that are in your active cell – a load balancer, Auto Scaling group, and so on.

A cell represents replicas of your application. Readiness checks in Route 53 ARC help you determine if your application is ready to fail over from one replica to another. However, you should make decisions about whether to fail away from or to a replica based on your monitoring and health check systems, and consider readiness checks as a complementary service to those systems.

Readiness checks audit resources to determine their readiness based on a set of pre-defined rules for that type of resource. After you create your recovery group with the replicas, you add Route 53 ARC readiness checks for the resources in your application, so Route 53 ARC can help make sure that the replicas have the same setup and configuration over time.

Creating recovery groups

The steps in this section explain how to create a recovery group on the Route 53 ARC console. To learn about using recovery readiness API operations with Amazon Route 53 Application Recovery Controller, see Readiness check API operations.

To create a recovery group

  1. Open the Route 53 ARC console at https://console.amazonaws.cn/route53recovery/home#/dashboard.

  2. Choose Readiness check.

  3. On the Recovery readiness page, choose Create, and then choose a Recovery group.

  4. Enter a name for your recovery group, and then choose Next.

  5. Choose Create cells, and then choose Add cell.

  6. Enter a name for the cell. For example, if you have an application replica in US West (N. California), you could add a cell named MyApp-us-west-1.

  7. Choose Add cell, and add a name for a second cell. For example, if you have a replica in US East (Ohio), you could add a cell named MyApp-us-east-2.

  8. If you want to add nested cells (replicas in Availability Zones within Regions), choose Action, choose Add nested cell, and then enter a name.

  9. When you've added all of the cells and nested cells for your application replicas, choose Next.

  10. Review your recovery group, and then choose Create recovery group.

Updating and deleting recovery groups and cells

The steps in this section explain how to update and delete a recovery group, and delete a cell on the Route 53 ARC console. To learn about using recovery readiness API operations with Amazon Route 53 Application Recovery Controller, see Readiness check API operations.

To update or delete a recovery group, or delete a cell

  1. Open the Route 53 ARC console at https://console.amazonaws.cn/route53recovery/home#/dashboard.

  2. Choose Readiness check.

  3. On the Recovery readiness page, choose a recovery group.

  4. To work with a recovery group, choose Action, and then choose Edit recovery group or Delete recovery group.

  5. When you edit a recovery group, you can add or remove cells or nested cells.

    • To add a cell, choose Add cell.

    • To remove a cell, under the Action label next to the cell, choose Delete cell.
