LoadBalancer

A Java-based Round Robin Load Balancer that distributes incoming requests evenly across multiple servers using a simple rotation algorithm.

Why I Built This

I built this project to get a better understanding of how requests are distributed across servers. Load balancing is a common concept in backend systems, and this was a simple way to explore how the Round Robin algorithm works in practice using Java.

Features

• Round Robin request distribution
• Dynamic server addition
• Even workload distribution across servers
• Circular server rotation
• Lightweight and easy-to-understand implementation
• Object-oriented design using separate classes

Technologies Used

• Java
• Java Collections Framework
• ArrayList
• Object-Oriented Programming (OOP)

How to Run

1. Clone the repository

git clone https://github.com/JavaLabs-io/LoadBalancer.git

2. Open the project in VS Code or any Java IDE

3. Run Main.java

Sample Output

Added: Server A
Added: Server B
Added: Server C

Request 1 -> Server A
Request 2 -> Server B
Request 3 -> Server C
Request 4 -> Server A
Request 5 -> Server B
Request 6 -> Server C

Future Improvements

• Remove server functionality
• Weighted Round Robin implementation
• Server health checks
• REST API integration
