A Warm Standby strategy for features such as Amazon SQS queues is similar to the [Pilot Light]({{< ref "/services/app_integration/sqs/pilot-light" >}} "Pilot Light") scenario.

Serverless resources are charged as you use, so while there is no traffic in the DR region, there are no costs for existing resources.
