Welcome to the LoadBalancer.DistributedAlgorithms2 project! This is a fun and educational distributed system built with .NET 9, designed to explore load balancing, fault tolerance, and monitoring.

🗓️ This project distributes computational tasks across worker nodes, caches results with Redis, and monitors metrics with Prometheus and Grafana — all within Docker containers.

This project simulates a distributed system where a load balancer distributes calculation requests to worker nodes. It features:

• A single .NET 9 codebase that acts as either a load balancer or worker node.
• Redis caching to boost performance.
• Prometheus + Grafana for monitoring.
• Fault-tolerant load balancing.
• Fully containerized using Docker.

• Load Balancing: Distributes tasks to 3 worker instances.
• Fault Tolerance: Uses Polly for retries and circuit breakers.
• Caching: Caches results in Redis to prevent redundant work.
• Monitoring: Collects and visualizes metrics.
• Dockerized: Runs seamlessly in containers.

• Docker Desktop (with WSL2 enabled on Windows)
• .NET 9 SDK (optional for local dev)
• PowerShell / Command Prompt

1. Clone the Repository:

   git clone https://github.com/mohammedabdelaleem/LoadBalancer.DistributedAlgorithms2.git
   cd LoadBalancer.DistributedAlgorithms2

2. Build and Run:

   docker-compose down --rmi all
   docker system prune -a -f
   docker-compose up --build

   The first build may take several minutes.

3. Verify:

   • Look for Redis and app logs in the terminal.
   • If it fails, check the Troubleshooting section below.

curl "http://localhost:3000/api/calculation/cal?n=1"

curl http://localhost:5002/health

curl http://localhost:3000/metrics

docker-compose stop worker2

docker-compose down
