In regards to Internet hosting, cloud architecture refers to using a separate server for each and every part of the Internet hosting service. Such a setup results in much better performance because one machine will be used only for file storage, a different one only for running databases, and so on, so different system processes will not run on the exact same machine. This will minimize the probability of system errors considerably and will allow your websites to operate faster, not mentioning the greater uptime. When you are looking for this kind of service, it is important to make sure that you'll really receive it since many companies advertise cloud internet hosting plans, yet the control panels they use aren't designed to function in a true cloud and can function only on one server. The problem with using one machine is that in case one service crashes or generates high load, the whole server will most likely go offline, so your Internet sites will no longer be accessible.
