It enforces priorities, and runs jobs from higher-priority queues in preference to lower-priority ones when the queues share a common Compute Environment.

The AWS Batch Scheduler is FIFO-based, and is aware of dependencies between jobs.

Scheduler – Attached to a Job Queue, a Scheduler decides when, where, and how to run Jobs that have been submitted to a Job Queue. A priority value is associated with each queue. Job Queue – Where Jobs reside until scheduled onto a Compute Environment. Many of the specifications in a Job Definition can be overridden by specifying new values when submitting individual Jobs. The definition can also control container properties, environment variables, and mount points. Includes an AWS Identity and Access Management (IAM) role to provide access to AWS resources, and also specifies both memory and CPU requirements. Job Definition – Specifies how Jobs are to be run. Jobs can reference other jobs by name or by ID, and can be dependent on the successful completion of other jobs. It has a name, and runs as a containerized app on EC2 using parameters that you specify in a Job Definition. Job – A unit of work (a shell script, a Linux executable, or a container image) that you submit to AWS Batch. Let’s start by taking a look at some important AWS Batch terms and concepts (if you are already doing batch computing, many of these terms will be familiar to you, and still apply). It is efficient, easy to use, and designed for the cloud, with the ability to run massively parallel jobs that take advantage of the elasticity and selection provided by Amazon EC2 and EC2 Spot and can easily and securely interact with other other AWS services such as Amazon S3, DynamoDB, and SNS. AWS Batch takes care of the undifferentiated heavy lifting and allows you to run your container images and applications on a dynamically scaled set of EC2 instances.

There’s nothing to buy and no software to install. AWS Batch allows batch administrators, developers, and users to have access to the power of the cloud without having to provision, manage, monitor, or maintain clusters. Today I would like to tell you about a new set of fully-managed batch capabilities. This turned out to be a very common AWS use case and we decided to make it even easier to achieve.

In the past, many AWS customers have built their own batch processing systems using EC2 instances, containers, notifications, CloudWatch monitoring, and so forth. We believe that cloud computing has the potential to change the batch computing model for the better, with fast access to many different types of EC2 instances, the ability to scale up and down in response to changing needs, and a pricing model that allows you to bid for capacity and to obtain it as economically as possible. Clusters are expensive to build and to maintain, and are often comprised of a large array of identical, undifferentiated processors, all of the same vintage and built to the same specifications. Once again, priorities come in to play and there never seems to be enough compute power to go around. Many organizations have attempted to feed these needs by building in-house compute clusters powered by open source or commercial job schedulers.

Today, batch computing remains important! Easier access to compute power has made movie studios, scientists, researchers, numerical analysts, and others with an insatiable appetite for compute cycles hungrier than ever. Student productivity was assuredly secondary to efficient use of resources. The goal of the entire priority mechanism was to keep the expensive hardware fully occupied whenever possible. As my fellow students and I quickly learned, jobs launched by the school’s IT department ran at priority 4 while ours ran at 8 their jobs took precedence over ours. I studied that printed output with care, and was always shocked to find that after my jobs spent several hours waiting for its turn to run, the actual run time was just a few seconds.

I would take the deck to the submission window, hand it to the operator in exchange for a job identifier, and then come back several hours later to collect the printed output and the card deck.

I quickly learned how to use the keypunch machine to prepare my card decks, prefacing the actual code with some cryptic Job Control Language (JCL) statements that set the job’s name & priority, and then invoked the FORTRAN, COBOL, or PL/I compiler. The Computer Science department at Montgomery College was built around a powerful (for its time) IBM 370/168 mainframe.
