Distributed Chat Backend with Redundancy

This project is a Python-based backend designed to handle message storage in a database and ensure high availability and redundancy through communication between multiple backend instances using message queues (RabbitMQ).

⚙️ Key Features

• 💬 Stores incoming chat messages in a relational database.
• 🔁 Redundancy and synchronization across multiple backend instances.
• 🕸️ Inter-process communication using RabbitMQ.
• 🔐 Horizontally scalable architecture.
• 🚀 Ready for deployment in Docker/Kubernetes environments.

🧱 High-Level Architecture

+-----------+       +-------------+       +-----------+
| Frontend  | <---> |  Backend A  | <---> |  Backend B |
+-----------+       +-------------+       +-----------+
                        ↑   ↓                  ↑   ↓
                      [RabbitMQ] <----------> [RabbitMQ]
                        ↑   ↓                  ↑   ↓
                      [Database]            [Database]

All backend instances are synchronized via message queues, allowing for load distribution and consistency.
