Microservices Blog

Notes: You need to have docker, docker kubernetes installed.

Functionality

This project is based on the creation of a simple blog, where the user can add posts and comments to them. It is created with a basic structure of microservices. It also contains a custom event bus built to understand how asynchronous microservices work.

Microservices List

• Comments (in charge of creating and listing comments)
• Event Bus (in charge of asynchronous communication between microservices)
• Moderation (in charge of approving, rejecting comments)
• Posts (in charge of creating and listing posts)
• Query (in charge of joining the posts and comments data)
