Step Functions Workflow: Route S3 Uploads to Lambda or Fargate Overview This skill deploys an event-driven workflow using AWS CLI. When a file is uploaded to an S3 bucket, EventBridge triggers a Step Functions state machine. The state machine checks the file size and routes processing to either a Lambda function (files ≤ 6 MB) or a Fargate task (files > 6 MB). The architecture includes: An S3 bucket with EventBridge notifications enabled An EventBridge rule that triggers Step Functions on S3 object creation A Step Functions state machine with a Choice state for routing A Lambda function for processing small files An ECS Fargate task for processing large files A VPC with two subnets, internet gateway, and security group An ECR repository for the Fargate container image Scoped IAM roles for Lambda, Step Functions, and ECS tasks Show more Installs 766 Repository aws/agent-toolk…-for-aws GitHub Stars 2.0K First Seen Jun 18, 2026 Security Audits Gen Agent Trust Hub Pass Socket Pass Snyk Pass
