Tutorial by Rishi Raj Gautam on linuxhandbook.com focusing on load balancers. Having a proper set up of load balancer allows your web server to handle high traffic smoothly instead of crashing down. In this tutorial, he explains how to setup a load balancer with high availability.
Load balancing is the process of distributing workloads to multiple servers. It is like distributing workloads between day shift and night shift workers in a company.
In this tutorial, we are going to set up a load balancer for web server using Nginx, HAProxy and Keepalived. Out of three the less known is Keepalived. [Keepalived] is an open-source program that supports both load balancing and high availability. It is basically a routing software and provides two types of load balancing:
