Using an event-driven architecture with serverless components in AWS can significantly enhance decoupling, scalability, and reliability. AWS Step Functions is a powerful workflow management service that enables you to orchestrate multiple AWS services efficiently.
Key Components of the Architecture
- AWS Step Functions – Manages workflows with sequential, parallel, or conditional execution.
- Amazon EventBridge Scheduler – Triggers workflows at specified times or intervals.
- AWS Batch – Handles batch processing jobs in ECS or EKS without manual infrastructure management.
Example Workflow: ETL Processing
The architecture discussed by Daniel Alejandro Figueroa Arias replaces a tightly coupled system with a scalable, event-driven approach:
– EventBridge Scheduler initiates the workflow.
– Step Functions coordinates tasks, including parallel processing.
– AWS Batch executes compute-heavy ETL jobs efficiently.

You Should Know: Practical Implementation
1. Setting Up AWS Step Functions
Define a state machine using Amazon States Language (ASL):
{
"Comment": "ETL Job Orchestration",
"StartAt": "TriggerETL",
"States": {
"TriggerETL": {
"Type": "Task",
"Resource": "arn:aws:states:::batch:submitJob.sync",
"Parameters": {
"JobDefinition": "etl-job-definition",
"JobQueue": "etl-job-queue",
"JobName": "ETLProcess"
},
"End": true
}
}
}
2. Configuring EventBridge Scheduler
Use AWS CLI to create a rule:
aws events put-rule \ --name "ETL-Daily-Trigger" \ --schedule-expression "cron(0 2 ? )" \ --state "ENABLED"
3. Deploying AWS Batch
Create a compute environment:
aws batch create-compute-environment \ --compute-environment-name "ETL-Compute" \ --type "MANAGED" \ --state "ENABLED" \ --service-role "arn:aws:iam::123456789012:role/AWSBatchServiceRole" \ --compute-resources "type=FARGATE,maxvCpus=8,subnets=[subnet-12345]"
4. Monitoring the Workflow
Check Step Function execution logs:
aws stepfunctions get-execution-history \ --execution-arn "arn:aws:states:us-east-1:123456789012:execution:ETLStateMachine:abc123"
What Undercode Say
This architecture leverages AWS serverless services to build a resilient, scalable ETL pipeline. Key takeaways:
– Step Functions simplify workflow management.
– EventBridge ensures timely execution.
– AWS Batch eliminates manual job scheduling.
For further optimization:
- Use AWS Lambda for lightweight tasks.
- Integrate S3 Event Notifications for file-triggered workflows.
- Monitor performance with CloudWatch Metrics.
🔧 Essential Linux Commands for AWS Debugging:
Check AWS CLI configuration aws configure list Inspect running ECS tasks aws ecs list-tasks --cluster etl-cluster Fetch CloudWatch logs aws logs tail /aws/batch/job --follow List Step Function executions aws stepfunctions list-executions --state-machine-arn "arn:aws:states:..."
🔧 Windows Equivalent (PowerShell):
Get AWS Batch job status Get-BATJobList -JobQueue "etl-job-queue" Monitor EventBridge rules Get-CWERule -Name "ETL-Daily-Trigger"
Expected Output:
A fully automated, decoupled ETL system that scales dynamically while reducing operational overhead.
