Grouping resources in an Application Component - AWS Resilience Hub

Grouping resources in an Application Component

When the application is imported into AWS Resilience Hub along with its resources, AWS Resilience Hub makes its best effort to group related resources into the same AppComponent, but might not always be 100 percent accurate. In addition, AWS Resilience Hub performs the following activities after your application and its resources are successfully imported:

  • Scans your resources to check if they can be re-grouped into new AppComponents to improve the assessment accuracy.

  • If AWS Resilience Hub identifies resources that can be re-grouped into new AppComponents, it displays the same as recommendations and allows you to either accept, modify (add or remove), or reject the same. In AWS Resilience Hub, the confidence level assigned to a grouping recommendation indicates the degree of certainty with which the resources should be grouped together based on their attributes and metadata. A High confidence level indicates that AWS Resilience Hub has a confidence level of 90% or above that the resources in that group are related and should be grouped together. A Medium confidence level indicates that AWS Resilience Hub has a confidence level between 70% and 90% that the resources in that group are related and should be grouped together.

Note

AWS Resilience Hub requires the correct grouping so that it can compute estimated workload RTO and estimated workload RPO to generate recommendations.

The following are examples of correct groupings:

  • Group primary databases and replicas under a single AppComponent.

  • Group an Amazon S3 bucket and its target replication under a single AppComponent.

  • Group Amazon EC2 instances that run the same application under a single AppComponent.

  • Group an Amazon SQS queue and its dead-letter queue under a single AppComponent.

  • Group Amazon ECS services in one Region and failover Amazon ECS services in another Region under a single AppComponent.
