When it comes to Internet hosting, cloud architecture refers to using a different server for each and every part of the Internet hosting service. Such a configuration results in improved performance as one machine will be used just for file storage, another one only for running databases, and so on, therefore different system processes will not run on the very same machine. This will lessen the chance of system errors substantially and will allow your websites to run faster, not mentioning the better uptime. If you are looking for this kind of service, you need to make certain that you will really find it since numerous companies advertise cloud hosting plans, however the control panels they use aren't designed to work in a true cloud and can function only on a single server. The issue with using just a single machine is that in case one service goes down or generates high load, the entire server will possibly go offline, so your websites will no longer be accessible.
