Simple Load Balancer with Round Robin Algorithm

This project is a basic implementation of a load balancer in Go using the Round Robin algorithm. The load balancer distributes incoming HTTP requests to a set of backend servers in a circular order. The project also has Three RESTApi.

A load balancer performs the following functions:

• Distributes client requests/network load efficiently across multiple servers
• Ensures high availability and reliability by sending requests only to servers that are online
• Provides the flexibility to add or subtract servers as demand dictates

Therefore our goals for this project are to:

• Build a load balancer that can send traffic to two or more servers.
• Health check the servers.
• Handle a server going offline (failing a health check).
• Handle a server coming back online (passing a health check).

Tech Stack Used are:

Web Framework

• Net/HTTP
• Gin

Algorithm Implementation

• Round Robin Logic: Custom implementation of the Round Robin algorithm to distribute requests evenly across multiple backend servers.
