Pricing
You pay for Application Recovery Controller based on two dimensions: readiness checks and clusters. You pay only for what you use and there are no upfront charges to use Application Recovery Controller
Readiness check
Readiness check audits your resources across Availability Zones or Regions to help you ensure that they are prepared for a recovery. You pay $0.045 per hour for every readiness check that you configured. For example, if you have modeled an application using Application Recovery Controller and have a readiness check for Auto Scaling Groups and another for DynamoDB tables, you will have two readiness checks configured, each charging $0.045. So, your total readiness check bill will be $0.09 per hour.
Cluster
A cluster is a set of redundant regional endpoints against which you can execute API calls to update or get the state of one or more routing controls. You pay $2.5 per hour for every cluster configured. Each cluster (maximum 2) can host multiple routing controls, which you can use to trigger failovers.
