An HA cluster is a loosely coupled group of systems, generally organized around some sort of shared storage. This diagram shows the major components of such a cluster.
Take a close look – note that every piece of the system has a backup. When architected properly, if any component fails, a backup component will step up and take its place. A few years ago, this kind of engineering was reserved for organizations such as NASA, Fortune 500 companies, and others with lots of money. Today, this technology is affordable and available for the masses. If you’re a small organization and downtime is important, you need to contact us and learn how this technology can help you sleep better at night.
