When deciding upon server architecture, most businesses start out with a single server architecture and then build up as needs present themselves. With this tutorial we are going to give you a quick run through of taking your server environment to a position where you have a lot more redundancy at a low cost.

In order to be able to follow this tutorial you are going to need a basic knowledge of how to connect  to servers via SSH and how to get setup your application or database on these servers. We also generally use Ubuntu as our server of choice, however this tutorial will be vaguely the same across most versions of Linux.
