S3 Event Processing Pipeline
CloudFormation: S3 upload event triggers Lambda processor, result written to DynamoDB, failures routed to SQS DLQ with CloudWatch alarm.
S3 Event Processing Pipeline — S3, Lambda, DynamoDB, SQS
A production-ready event-driven pipeline that processes every file uploaded to S3 in real time. Results land in DynamoDB, failures route to SQS DLQ, and CloudWatch alarms tell you when things break.
What's Included
- S3 bucket with ObjectCreated event notification to Lambda
- Lambda processor (Node.js 22) writing results to DynamoDB
- DynamoDB table for processing records with status tracking
- SQS DLQ as Lambda failure destination
- CloudWatch alarm on DLQ depth
- IAM roles with least-privilege permissions
Developer Experience
Upload a file to S3 and watch the Lambda fire, process the object, and write the result to DynamoDB within seconds. Extend for image resizing, document parsing, or any file processing use case.
What You Get
A complete, observable pipeline from upload to processed record. Every failure captured in the DLQ. Extend the Lambda handler for your specific use case.
Requirements
AWS CLI v2 with CloudFormation, S3, Lambda, DynamoDB, SQS, IAM, and CloudWatch permissions.
