Serverless architecture Image Processing with S3 and Lambda

This project implements a Serverless Image Processing Pipeline on AWS using S3 and Lambda.

When users upload images to an S3 bucket, a Lambda function is automatically triggered to process them — resizing, optimizing, converting to WebP, or adding watermarks. The processed images are then stored in a separate destination bucket, ready for users to download or integrate into applications.

The solution is fully serverless, which means no servers to manage, automatic scaling, and pay-as-you-go cost efficiency. It’s secure with IAM roles and S3 policies, and optimized with lifecycle rules and monitoring.

Use cases include:

E-commerce platforms to optimize product images

Social media apps for user-uploaded photos

Content management systems (CMS) handling media at scale

This architecture ensures a scalable, cost-effective, and secure way to handle image processing in the cloud.
