Job Queues - AWS Batch

Job Queues

Jobs are submitted to a job queue, where they reside until they are able to be scheduled to run in a compute environment. An AWS account can have multiple job queues. For example, you might create a queue that uses Amazon EC2 On-Demand instances for high priority jobs and another queue that uses Amazon EC2 Spot Instances for low-priority jobs. Job queues have a priority that is used by the scheduler to determine which jobs in which queue should be evaluated for execution first.
