When it comes to Internet hosting, cloud architecture refers to using an independent server for each aspect of the hosting service. Such a configuration leads to a lot better performance as one machine will be used just for file storage, a different one just for running databases, and so on, therefore different system processes will not run on the very same machine. This will minimize the chance of system errors substantially and will allow your Internet sites to run faster, not mentioning the greater uptime. When you're looking for this kind of service, you have to make sure that you'll really receive it as many companies advertise cloud web hosting plans, but the control panels they use aren't designed to function in a real cloud and can function only on one server. The issue with using a single machine is that in the event that one service goes down or generates high load, the whole server will almost certainly go offline, so your Internet sites will no longer be accessible.
