How to: Batch Tips
- AWS Batch supports prioritization of jobs via the Job Queue Priority. Higher the number - higher the priority.
- AWS Batch supports launching the Compute Environment into specific VPC and subnets.
- A Compute Environment is same as an [ECS Cluster](http://docs.aws.amazon.com/AmazonECS/latest/developerguide/ECS_clusters.html).
- There is no additional cost for AWS Batch. You only pay the cost associated with the AWS Services being used - like EC2 Instances and any resources consumed by the batch jobs.
- Associate [IAM Roles and policies](http://docs.aws.amazon.com/batch/latest/userguide/IAM_policies.html) with the Compute Environment to enable the containers access to other AWS resources.
- 🔹 Use Unmanaged Compute Environments if you need specialized resources like Dedicated Hosts, or [EFS](https://aws.amazon.com/efs/).
