Now that you have configured AWS Batch, take a look at your environment by using the following commands
aws batch describe-compute-environments --region $AWS_REGION
aws batch describe-job-queues --region $AWS_REGION
aws batch describe-job-definitions --region $AWS_REGION
You will see that the JSONs provided as output contain the parameters you chose for the compute environment, job queue, and job definition. Keep in mind that the steps you completed previously using the AWS CloudFormation can also be completed with the AWS CLI, AWS SDK, or AWS Console.
