// Creates a Resilience Hub application. A Resilience Hub application is a
// collection of Amazon Web Services resources structured to prevent and recover
// Amazon Web Services application disruptions. To describe a Resilience Hub
// application, you provide an application name, resources from one or more–up to
// five–CloudFormation stacks, and an appropriate resiliency policy. After you
// create a 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).
