 # Practical Tuples
 
-This project is a to-do type application built on serverless real-time architecture. The app's frontend is built with [Angular](https://angular.io/) and the backend is built with [NestJS](https://nestjs.com/), and uses a [PostgreSQL](https://www.postgresql.org/) relational database. The app can be hosted in AWS with the frontend in [S3](https://aws.amazon.com/s3/) and the backend in [Lambda](https://aws.amazon.com/lambda/), managed by the [Serverless](https://www.serverless.com/) framework. Real-time communication between the frontend and backend is performed by persistent websocket connection that is maintained by [API Gateway](https://aws.amazon.com/api-gateway/).
