# AWS::Route53RecoveryReadiness::Cell
<a name="aws-resource-route53recoveryreadiness-cell"></a>

Creates a cell in recovery group in Amazon Route 53 Application Recovery Controller. A cell in Route 53 ARC represents replicas or independent units of failover in your application. It groups within it all the AWS resources that are necessary for your application to run independently. Typically, you would have define one set of resources in a primary cell and another set in a standby cell in your recovery group.

After you set up the cells for your application, you can create readiness checks in Route 53 ARC to continually audit readiness for AWS resource quotas, capacity, network routing policies, and other predefined rules.

You can set up notifications about changes that would affect your ability to fail over to a replica and recover. However, you should make decisions about whether to fail away from or to a replica based on your monitoring and health check systems. You should consider readiness checks as a complementary service to those systems.

Route 53 ARC Readiness supports us-east-1 and us-west-2 AWS Regions only.

# AWS::Route53RecoveryReadiness::ReadinessCheck

Creates a readiness check in Amazon Route 53 Application Recovery Controller. A readiness check continually monitors a resource set in your application, such as a set of Amazon Aurora instances, that Route 53 ARC is auditing recovery readiness for. The audits run once every minute on every resource that's associated with a readiness check.

Every resource type has a set of rules associated with it that Route 53 ARC uses to audit resources for readiness. For more information, see [Readiness rules descriptions](https://docs.aws.amazon.com/r53recovery/latest/dg/recovery-readiness.rules-resources.html) in the Amazon Route 53 Application Recovery Controller Developer Guide.

# AWS::Route53RecoveryReadiness::RecoveryGroup

Creates a recovery group in Amazon Route 53 Application Recovery Controller. A recovery group represents your application. It typically consists of two or more cells that are replicas of each other in terms of resources and functionality, so that you can fail over from one to the other, for example, from one Region to another. You create recovery groups so you can use readiness checks to audit resources in your application.

# AWS::Route53RecoveryReadiness::ResourceSet

You typically create a resource set and a readiness check for each supported type of AWS resource in your application.
