Creating resiliency policies

In AWS Resilience Hub, you can create a resiliency policy. A resiliency policy contains information and objectives that you use to assess whether your application can recover from a disruption type, such as software, hardware, Availability Zone, or AWS Region. Resiliency policies are guidelines that measure your objectives. These policies do not change or affect an actual application. Multiple applications can have the same resiliency policy.

When you create a resiliency policy, you define the objectives: Recovery Time Objective (RTO) and Recovery Point Objective (RPO). The objectives determine whether the application meets the resiliency policy. Attach the policy to your application and run a resiliency assessment.

The assessment evaluates your application configuration against the attached resiliency policy. At the end of the process, AWS Resilience Hub provides an assessment of how your application measures against the objectives in your resiliency policy.

You can create resiliency policies in Applications, and also in Resiliency policies. You can access relevant details about your policies, and also modify and delete them.

To create resiliency policies in Applications

1. In the left navigation menu, choose Applications.

2. In Applications, choose Add Application. Then choose either Quick Start or Walk-through (guided instructions). Based on your selection, proceed to step 3 or step 4.

3. If you choose Quick Start, enter a name and optional description, and then choose Add. You can add resources and resiliency policies later.

4. If you choose Walk-through:

   • In Describe application details, enter the name and an optional description. Choose Next.

   • Specify how your application discovers resources from either existing applications, or AWS CloudFormation stacks.

   • In Resiliency policies, choose Create a new policy.

     • If you know how you want to set up your resiliency policy, choose Create a policy.

       • Name and describe the policy and select the tier that defines the policy.

       • Enter RTO and RPO values for Hardware disruption, Software disruption, Availability Zone disruption, and Region disruption (Region is optional).

       • Choose Create to complete the process.

     • If you need recommendations to set up your resiliency policy, choose Select a policy from suggestions.

       • Name and describe the policy.

       • Choose one of the following resiliency policies. You can get any details about the policy later.

         Non-Critical Application, Important Application Tier, Critical Application Tier, Global Critical Application Tier, Mission Critical Application Tier, Global Mission Critical Application Tier, and Foundational Core Service Tier. You can get details about the policy later.

       • Choose Create to complete the process.

To create resiliency policies in Resiliency policies

1. In the left navigation menu, choose Resiliency policies.

2. In Resiliency policies, choose Create a new policy.

   • Name and describe the policy and select the tier that defines the policy.

   • Enter RTO and RPO values for Hardware disruption, Software disruption, Availability Zone disruption, and Region disruption (optional).

   • Choose Create to complete the process.

3. You can add internal tags to search, filter, and manage your AWS resources in your application.

   • To add tags, choose Add new tag.

   • Enter information in the Key and Value fields.

To create resiliency policies based on a suggested policy

1. In the left navigation menu, choose Resiliency policies.

2. In Resiliency policies, choose Select a policy based on a suggested policy.

   • Name and describe the policy.

   • Choose one of these resiliency policies:

     Non-Critical Application, Important Application Tier, Critical Application Tier, Global Critical Application Tier, Mission Critical Application Tier, Global Mission Critical Application Tier, and Foundational Core Service Tier. You can get details about the policy later.

   • Input the Customer application RTO and RPO targets.

   • Input the Cloud Infrastructure RTO and RPO targets.

   • Choose Create to complete the process.

3. You can add internal tags to search, filter, and manage your AWS resources in your application.

   • To add tags, choose Add new tag.

   • Enter information in the Key and Value fields.
