Step 8: Select a policy for your application

An AWS Resilience Hub resiliency policy contains information and objectives that are used to assess whether your application can recover from a disruption, such as an application or infrastructure disruption. When you create a resiliency policy, you define the recovery time objective (RTO) and recovery point objective (RPO) for the disruption types. These objectives determine whether the application meets the resiliency policy.

When you create a new policy or select an existing Resilience Hub resiliency policy, consider your resiliency objectives and potential disruptions. For example, consider the business impact of the application, and the RTO and RPO targets that you want your application to meet. Also, identify the most concerning disruptions that your application might encounter, as you can set RTO and RPO goals for each disruption type.

Use a suggested policy or create a new policy to get started.

To create a resiliency policy

1. Select Create resiliency policy.

   The Create resiliency policy page displays.

2. In Choose a creation method section, select Create a policy.

3. Enter a name for the policy.

4. (Optional) Enter a description for the policy.

5. Choose one of the following from Tier dropdown list:

   • Foundational IT core services

   • Mission critical

   • Critical

   • Important

   • Non critical

6. For both RTO and RPO, under Customer Application RTO and RPO, enter a numeric value in the box, and then choose the unit of time that the value represents.

   Repeat these entries under Infrastructure RTO and RPO for Infrastructure and Availability Zone.

7. (Optional) If you have a multi-Region application, you may want to define a Region RTO and RPO.

   Turn-on Region. For both RTO and RPO, under Customer Application RTO and RPO, enter a numeric value in the box, and then choose the unit of time that the value represents.

8. (Optional) If you want to add tags, you can do that later as you continue creating your policy. For more information about tags, see Tagging resources in the AWS General Reference.

9. To create the policy, choose Create.

10. Verify that your newly created policy is selected by default from the list of policies under Resiliency policies, and choose Next.
