Description:  |
  This CloudFormation Template supports the requirements of an AWS Blog Post on Route 53 Application Recovery Controller.
  It is the second part of a three part CloudFormation Deployment. It has dependencies on the preceeding [1] base infrastructure deployment, and is required for [3] supporting Lambda deployment.
  It should be deployed as a standard Stack in us-east-1, within a single AWS account.
  It will deploy the following Route 53 Application Recovery Controller components:
  A) Recovery Readiness Groups, Cells, and Resource Sets
  B) Routing Control Clusters, Control Panels, Routing Controls, Safety Rules, and Healthchecks
  C) Route 53 DNS Private Hosted Zone and associated DNS entries
  This template is provided as a sample for educational purposes and should NOT be considered production ready.
#  Note that this template is designed in a modular way, and most relevant possible variables are stored in the 'Mappings > StaticParameters' section of the template.
#  These parameters can be modified by advanced users at their own risk.
#  Note that the resources deployed using this template will cost approx. $2.50/hr. Please be sure to clean up all resources by deleting the CloudFormation Stacks when they are no longer required.

Mappings:
