AWS Batch is a fully-managed service that enables developers, scientists, and engineers to easily and efficiently run batch computing workloads of any scale on AWS. AWS Batch automatically provisions compute resources and optimizes the workload distribution based on the quantity and scale of the workloads. With AWS Batch, there is no need to install or manage batch computing software, allowing you to focus on analyzing results and solving problems. AWS Batch plans, schedules, and executes your batch computing workloads across the full range of AWS compute services and features, such as Amazon EC2, Spot Instances, and AWS Lambda. AWS Batch reduces operational complexities, saving time and reducing costs. In this session, Principal Product Managers Jamie Kinney and Dougal Ballantyne describe the core concepts behind AWS Batch and details of how the service functions.  The presentation concludes with relevant use cases and sample code.

NEW LAUNCH!
Introducing AWS Batch
Easy and Efficient Batch Computing
on Amazon Web Services

2. Agenda
• A brief history of batch computing
• AWS Batch overview and concepts
• Use cases
• Let’s take it for a spin!
• Q&A

3. Run jobs asynchronously and automatically across one or
more computers.
Jobs may have dependencies, making the sequencing and
scheduling of multiple jobs complex and challenging.
What is batch computing?

In 2007 the New York Times
processed 130 years of archives in
36 hours.
11 million articles & 4 TB of data
AWS services used:
Amazon S3, SQS, EC2, and EMR
Total cost (in 2007): $890

15. Introducing AWS Batch
Fully managed
No software to install or
servers to manage.
AWS Batch provisions,
manages, and scales your
infrastructure
Integrated with AWS
Natively integrated with the
AWS platform, AWS Batch
jobs can easily and securely
interact with services such as
Amazon S3, DynamoDB, and
Rekognition
Cost-optimized
resource provisioning
AWS Batch automatically
provisions compute
resources tailored to the
needs of your jobs using
Amazon EC2 and Spot

16. Introducing AWS Batch
• Fully managed batch primitives
• Focus on your applications (shell scripts,
Linux executables, Docker images) and
their resource requirements
• We take care of the rest!

17. AWS Batch Concepts
• Jobs
• Job definitions
• Job queue
• Compute environments
• Scheduler

18. Job Queues
Jobs are submitted to a job queue, where they reside until they are
able to be scheduled to a compute resource.
$ aws batch create-job-queue --job-queue-name genomics
--priority 500 --compute-environment-order ...

19. AWS Batch Concepts
Job queues are mapped to one or more compute environments
containing the EC2 instances used to run containerized batch jobs.
Managed compute environments enable you to describe your business
requirements (instance types, min/max/desired vCPUs, and Spot bid
as a % of On-Demand) and we launch and scale resources on your
behalf.
Alternatively, you can launch and manage your own resources within
an unmanaged compute environment. Your instances need to include
the ECS agent and run supported versions of Linux and Docker.

20. Job Definitions
Similar to ECS task definitions, AWS Batch job definitions specify how
jobs are to be run. While each job must reference a job definition, many
parameters can be overridden.
Some of the attributes specified in a job definition:
• IAM role associated with the job
• vCPU and memory requirements
• Mount points
• Container properties
• Environment variables
$ aws batch register-job-definition --job-definition-name gatk
--container-properties ...

21. Jobs
Jobs are the unit of work executed by AWS Batch as containerized
applications running on Amazon EC2.
Containerized jobs can reference a container image, command, and
parameters or users can simply provide a .zip containing their
application and we will run it on a default Amazon Linux container.
$ aws batch submit-job --job-name variant-calling
--job-definition gatk --job-queue genomics

22. Easily run massively parallel jobs
Today, users can submit a large number of independent “simple jobs.”
In the coming weeks, we will add support for “array jobs” that run
many copies of an application against an array of elements.
Array jobs are an efficient way to run:
• Parametric sweeps
• Monte Carlo simulations
• Processing a large collection of objects

23. Workflows and Job Dependencies

24. Workflows, Pipelines, and Job Dependencies
Jobs can express a dependency on the successful
completion of other jobs or specific elements of an
array job.
Use your preferred workflow engine and language to
submit jobs. Flow-based systems simply submit jobs
serially, while DAG-based systems submit many jobs
at once, identifying inter-job dependencies.
$ aws batch submit-job –depends-on 606b3ad1-aa31-48d8-92ec-f154bfc8215f ...

25. AWS Batch Concepts
The Scheduler evaluates when, where, and
how to run jobs that have been submitted to
a job queue.
Jobs run in approximately the order in which
they are submitted as long as all
dependencies on other jobs have been met.

26. AWS Batch Pricing
There is no charge for AWS Batch; you only pay for the
underlying resources that you consume!

27. AWS Batch Availability
• Currently in preview in the US East (Northern Virginia) Region
• Support for array jobs and jobs executed as AWS Lambda
functions coming soon!
