AWS Event-Driven S3 Cleanup System

A serverless workflow that tracks S3 bucket size over time, triggers cleanup when thresholds are reached, and generates a final plot from workflow history.

This project is an event-driven serverless system that monitors bucket growth in S3, removes the largest object when a threshold is crossed, and generates a final plot showing how total bucket size changes over time.

AWS Event-Driven S3 Cleanup System architecture

What It Covers

S3 events fanned out through SNS and SQS
state tracking in DynamoDB
CloudWatch-based monitoring and alarm-driven cleanup
a plotting step that turns workflow history into a visual output

The useful part of this project is the combination of asynchronous event flow, state tracking, and monitoring-driven remediation in one small but realistic system.
