HAProxy & Webserver

This Post is all about HAProxy and Webserver configuration using Ansible.

So, What is HAProxy?

HAProxy is free, open source software that provides a high availability load balancer and proxy server for TCP and HTTP-based applications that spreads requests across multiple servers.

• Description

This all is automated using ansible
