Describing and managing AWS Resilience Hub Applications

An AWS Resilience Hub application is a collection of AWS resources that are structured to prevent and recover AWS application disruptions.

To describe an AWS Resilience Hub application, you provide an application name, resources from one or more AWS CloudFormation stacks, and an appropriate resiliency policy. You can also use any existing AWS Resilience Hub application as a template to describe your application.

After you describe an AWS Resilience Hub application, you must publish it so that you can run a resiliency assessment on it. You can then use recommendations from the assessment to improve resiliency by running another assessment, comparing results, and then reiterating the process until your estimated workload RTO and estimated workload RPO meet your RTO and RPO targets.

To view the Applications page, choose Applications from the navigation pane. You can identify your applications in the Applications page by the following:

  • Name – The name of the application you had provided while defining it in AWS Resilience Hub.

  • Description – The description of the application you had provided while defining it in AWS Resilience Hub.

  • Compliance status – AWS Resilience Hub sets the application status as Assessed, Not assessed, Policy breached, or is Changes detected.

    • Assessed - AWS Resilience Hub has assessed your application.

    • Not assessed - AWS Resilience Hub has not assessed your application.

    • Policy breached - AWS Resilience Hub has determined your application did not meet your resiliency policy's objectives for Recovery Time Objective (RTO) and Recovery Point Objective (RPO). Review and use the recommendations provided by AWS Resilience Hub before reassessing your application for resiliency. For more information about recommendations, see Add an application to AWS Resilience Hub.

    • Changes detected - AWS Resilience Hub has detected changes made to the resiliency policy associated with your application. You must reassess your application for AWS Resilience Hub to determine if your application meets your resiliency policy's objectives.

  • Scheduled assessments – The resource type identifies the component resource for your application. For more information about scheduled assessments, see Application resiliency.

    • Active - This indicates your application is automatically assessed daily by AWS Resilience Hub.

    • Disabled - This indicates your application is not automatically assessed daily by AWS Resilience Hub and you must manually assess your application.

  • Drift status – Indicates if your application has drifted or not from the previous successful assessment and sets one of the following statuses:

    • Drifted - Indicates that the application, which was compliant with its resiliency policy in the previous successful assessment, has now breached the resiliency policy and the application is at risk. Additionally, it also indicates if the resources within input sources, which are included in the current application version, were added or removed.

    • Not drifted - Indicates that the application is still estimated to meet its RTO and RPO targets defined in the policy. Additionally, it also indicates that the resources within input sources, which are included in the current application version, were not added or removed.

  • Estimated workload RTO – Indicates the maximum possible estimated workload RTO of your application. This value is the maximum estimated workload RTO of all the disruption types from the last successful assessment.

  • Estimated workload RPO – Indicates the maximum possible estimated workload RPO of your application. This value is the maximum estimated workload RTO of all the disruption types from the last successful assessment.

  • Last assessment time – Indicates the date and time your application was last assessed successfully.

  • Creation time – The date and time that the application was created.

  • ARN – The Amazon Resource Name (ARN) of your application. For more information about ARNs, see Amazon Resource Names (ARNs) in the AWS General Reference.

Note

AWS Resilience Hub can fully assess the resiliency of cross-region Amazon ECS resources only if you are using Amazon ECR for the image repository.

In addition, you can also filter the applications list by using one of the following options in the Applications page:

  • Find applications – Enter your application name to filter the results by the name of your application.

  • Filter last assessment time by a date and time range – To apply this filter, choose the calendar icon and select one of the following options to filter by the results that matches the time range:

    • Relative range – Select one of the available options and choose Apply.

      If you choose Customised range option, enter a duration in Enter duration box and select the appropriate unit of time from Unit of time dropdown list, then choose Apply.

    • Absolute range – To specify the date and time range, provide the start time and end time, and then choose Apply.

The following topics show the different approaches for describing an AWS Resilience Hub application and how to manage them.
