Serverless Note-Taking App Backend

This project demonstrates the basics of AWS serverless architecture by building the backend for a note-taking application. It utilizes AWS services such as API Gateway, Lambda, DynamoDB and AWS SAM (Serverless Application Model) for IaC. Additionally simple CI/CD pipline using AWS CodeCommit and CodePipeline is e set up tp automate deployments.

Features

• Serverless architecture
• CRUD operations for notes
• Infrastucture as Code using AWS SAM
• Automated CI/CD pipline with AWS CodeCommit and CodePipeline

Architecture Diagram and Used Services

Service Descriptions

AWS API Gateway

• Currently entrypoint for the note-taking app
• Manages routes HTTP requests to Lambda functions

AWS Lambda

• Handles the business logic for CRUD operations
• Triggered by API Gateway

AWS DynamoDB

• NoSQL database to store the notes
• NOTES_TABLE has partition key 'user_id' and sort key 'timestamp'
• NOTES_TABLE has also a GSI with the partition key 'note_id'

The project is created using AWS SAM to define the infrastructure with a simple template. It's uploaded to AWS CodeCommit repository and integrated with the CI/CD pipeline.

Next Steps

• Adding Amazon Cognito
• Adding Front End for the user.
