codemore.io (ARCHIVED)

This project was my first attempt at building a cloud-native microservices architecture that in theory is scalable and maintainable. This project is DISCONTINUED DUE TO ABUNDANT INCOMPLIANCES WITH IMPORTANT DEVOPS PRINCIPLES AND BEST PRACTICES.

The old architecture

In codemore.io, all client requests are sent to the broker service (which serves as an API gateway) with a JSON payload. The broker service will then redirect this request via gRPC to the correct microservice. The following mermaid visualizer depicts the architecture:

    Feed["<b>Feed</b><br>(WebSocket)"]
