Microservices Load Balancer

This project implements a microservices load balancer using Flask, designed to handle dynamic configuration updates, support multiple load balancing algorithms, provide HTTPS to microservices, implement circuit breakers and retries, offer a clean web UI, and support WebSocket and HTTP/2 protocols.

Features

  1. Load Balancing Algorithms: Implements Round Robin, Least Connections, and Weighted Round Robin algorithms.

  2. Dynamic Configuration: Dynamically updates configuration without requiring restarts.

  3. Health Checks: Implements health checks to direct traffic only to healthy servers.

  4. Scalability: Designed to scale horizontally, supporting auto-discovery of new servers and dynamic configuration updates.

  5. Logging and Monitoring: Provides logging to track requests, responses, and server health. Integrates with monitoring tools for performance insights.

  6. Security: Ensures secure handling of traffic, supporting SSL termination and security protocols.

  7. Circuit Breakers and Retries: Implements circuit breakers and retry mechanisms for enhanced reliability. WebSocket and HTTP/2 Support:

  8. Supports WebSocket and HTTP/2 protocols for diverse microservices communication.

Getting Started

  • Installation: pip install Flask
  • Run the Flask App: python app.py
  • Configuration: Update configuration dynamically using the /update-config endpoint.
  • Web UI: Access the web UI at http://localhost:5000.

Usage

  • Processing Requests: Send requests to the load balancer endpoint (/) for load-balanced processing.
  • Health Checks: Check the health of the load balancer at /health.
  • Updating Configuration: Use the /update-config endpoint to dynamically add or remove servers.
