SERVERLESS WEB APP

---

Project Overview

• This serverless web application is meticulously crafted around a three-tier microservices architecture, seamlessly integrating various AWS services.
• The application boasts a feature-rich frontend, deployed onto S3 and gracefully delivered through CloudFront.
• The backend, a Python marvel employing Boto3 modules, resides comfortably within AWS Lambda.
• DynamoDB, the robust NoSQL database, stores and manages data with finesse, while the glue holding everything together is a well-designed REST API orchestrated via AWS API Gateway.
