Serverless Thumbnailizer

Thumbnailizer is a serverless application, designed to automate the creation of thumbnails for images uploaded to an AWS S3 storage bucket. This application utilizes AWS services such as API Gateway, AWS Lambda, and S3 storage.

This architectural pattern creates REST API via API Gateway, acting as an S3 proxy for write operations. When an image is uploaded to the S3 bucket, the application automatically triggers a Lambda function through API Gateway. The Lambda function then retrieves the uploaded image from the S3 bucket and generates a thumbnail version of it. This thumbnail is subsequently stored back into the S3 bucket, enabling easy access to both the original image and its corresponding thumbnail.
