When hosting a website, maintaining constant availability is a must. Long outages can lead to a large loss in revenue and potential customers. To address this issue, the concept of high availability must be implemented. There are several methods of which to accomplish this, one however, in which we will explore is failover. More specifically, active passive failover. In our investigation, we will attempt to create a solution using corosync and pacemaker, services which help to monitor and implement solutions to maintain high availability. This will attempt to address the four principles of failover: transparency, speed, automation, and consistency.
