Solidifying Linux server solutions

Clustering is when a group of two or more computers (sometimes called nodes) work together as one single system in order to provide high availability of services for users.

When a failure occurs on one server in a cluster, resources are redirected and workload is redistributed to another networked server.

Clustering several servers makes both Linux web and database solutions many times more robust. The process is mostly undertaken by organisations that have mission critical websites/applications and businesses that are very serious about their internet presence.
