// Creates an Resilience Hub application. An Resilience Hub application is a
// collection of Amazon Web Services resources structured to prevent and recover
// Amazon Web Services application disruptions. To describe an Resilience Hub
// application, you provide an application name, resources from one or more
// CloudFormation stacks, Resource Groups, Terraform state files, AppRegistry
// applications, and an appropriate resiliency policy. For more information about
// the number of resources supported per application, see Service Quotas (https://docs.aws.amazon.com/general/latest/gr/resiliencehub.html#limits_resiliencehub)
// . After you create an Resilience Hub application, you 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 iterating the process until you achieve your goals for
// recovery time objective (RTO) and recovery point objective (RPO).
