Building a Scalable Batch Processing Serverless Pipeline with AWS Step Functions and Batch

Listen to this Post

In the realm of cloud computing, leveraging an event-driven approach with dynamic resources for on-demand processing is becoming increasingly popular. AWS Batch is a powerful service that allows you to run batch computing workloads on the AWS Cloud. It is highly flexible, supporting Elastic Container Service (ECS), Elastic Kubernetes Service (EKS), EC2, and serverless Fargate compute. This article explores how to build a scalable batch processing serverless pipeline using AWS Step Functions and Batch.

You Should Know:

1. AWS Batch Setup:

  • Create a Compute Environment:
    aws batch create-compute-environment --compute-environment-name my-compute-env --type MANAGED --state ENABLED --service-role arn:aws:iam::123456789012:role/AWSBatchServiceRole
    
  • Create a Job Queue:
    aws batch create-job-queue --job-queue-name my-job-queue --state ENABLED --priority 1 --compute-environment-order order=1,computeEnvironment=my-compute-env
    
  • Register a Job Definition:
    aws batch register-job-definition --job-definition-name my-job-def --type container --container-properties file://container-properties.json
    

2. AWS Step Functions:

  • Define a State Machine:
    {
    "Comment": "A simple AWS Step Functions state machine that uses AWS Batch",
    "StartAt": "SubmitBatchJob",
    "States": {
    "SubmitBatchJob": {
    "Type": "Task",
    "Resource": "arn:aws:states:::batch:submitJob.sync",
    "Parameters": {
    "JobName": "MyBatchJob",
    "JobQueue": "my-job-queue",
    "JobDefinition": "my-job-def"
    },
    "End": true
    }
    }
    }
    
  • Create the State Machine:
    aws stepfunctions create-state-machine --name "MyStateMachine" --definition file://state-machine-definition.json --role-arn arn:aws:iam::123456789012:role/StepFunctionsExecutionRole
