# Catter

This project aims to be a good example of how modern software systems are made. It'll demonstrate all modern best practices in software development, which includes both the architecture and the used technologies.

### Architecture of the software system

![](./resources/catter-architecture.png?raw=true "Architecture")

### Topics which are (will be) covered

- Client application with React

- Facebook and Google authentication with OpenID Connect (OAuth 2.0)

- Microservice Architecture

- REST services with Kotlin Spring Boot and with Go

- Reactive programming with Spring Webflux

- Multiple AWS services (DynamoDB, EC2, ECR, etc)

- Containerization with Docker

- Deployment with Kubernetes

- CI/CD with Jenkins

- Swagger UI for the REST APIs with proper unit testing for high code coverage

- Service Discovery with Spring Eureka

- RabbitMQ/Kafka for communication between the services

- Saga (Ochestrated/Choreographed) and Circuit Breaker patterns implemented

- Terraform modules and Helm charts for automated infrastructure

### Tutorial

I plan to go through all the covered topics step-by-step in a Medium article.

Stay tuned. It'll be published [here](https://medium.com/@danielgospodinow).
