mp4 to mp3 Converter - A Micro-Services Example

github: micro-serv-des

Welcome to the mp4 to mp3 converter, an example project showcasing micro-service system design concepts.

What is Micro-Service Design?

Micro-service design is an architectural style that structures an application as a collection of small, independent services. Each service runs in its own process and communicates with lightweight protocols typically over HTTP.

In a micro-service architecture, each service is designed to be:

• Independent: Each service can be developed, tested, and deployed independently of other services.
• Decentralized: Services are not tightly coupled, allowing for greater flexibility and scalability.
• Resilient: If one service fails or becomes unavailable, others can continue to function normally.

Overview

This project demonstrates how to design and implement a scalable, distributed system using multiple micro-services. The app converts MP4 files to MP3 audio files, utilizing various technologies such as Docker, Kubernetes, MySQL, MongoDB, RabbitMQ, and Flask.

Features

• Convert MP4 videos to MP3 audio files
• Authenticates users with JWT tokens
• Saves video metadata in a MongoDB database
• Sends email notifications upon conversion completion
• Utilizes RabbitMQ as the message broker

Architecture

The app consists of 6 micro-services:

1. Gateway: The main entry point, responsible for routing requests to the respective services.
2. Auth: Handles authentication and token validation using JWT.
3. Converter: Transforms MP4 videos into MP3 audio files.
4. Notify: Sends email notifications upon conversion completion.
5. rabbitmq: Handles queue for converter and notify service.

Technologies

• Docker
• Kubernetes
• MySQL
• MongoDB
• RabbitMQ
• Flask

TODO

• Add Tests
• Implement the registration feature (planned for v0.2)
• Migrate the Gateway service to Django (planned for v0.3)
