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

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.
