How does the AWS Compute Environment order of AWS Batch Job Queue work?

[thienntb]

I have a job queue as below:

{
    "jobQueueName": "${MC_QUEUE_NAME}",
    "state": "ENABLED",
    "priority": 10,
    "computeEnvironmentOrder": [
        {
            "order": 1,
            "computeEnvironment": "${SPOT_COMPUTE_ENV_ARN}"
        },
        {
            "order": 2,
            "computeEnvironment": "${ONDEMAND_COMPUTE_ENV_ARN}"
        }
    ]
}

Does the AWS use the second compute environment (on demand) in case AWS does not have any available spot instances at that time?
