In regards to hosting, cloud architecture refers to using a separate server for each and every aspect of the web hosting service. Such a setup provides improved performance as one machine will be used only for file storage, a different one just for running databases, and so on, therefore different system processes will not run on the exact same machine. This will lessen the probability of system errors substantially and will allow your Internet sites to operate faster, not mentioning the greater uptime. In case you're looking for this kind of service, you need to make sure that you will really find it since numerous companies advertise cloud hosting packages, yet the control panels they use are not designed to function in a true cloud and can work only on a single server. The problem with using just a single machine is that if one service fails or generates high load, the entire server will most likely go offline, so your Internet sites will no longer be accessible.
