In regards to hosting, cloud architecture refers to using an independent server for each part of the Internet hosting service. Such a configuration results in significantly better performance as one machine will be used only for file storage, another just for running databases, and so on, which means that different system processes will not run on the very same machine. This will lessen the probability of system errors significantly and will allow your Internet sites to run faster, not mentioning the greater uptime. If you're looking for this type of service, you have to make certain that you'll really receive it because a lot of companies advertise cloud web hosting plans, but the control panels they use aren't designed to work in a real cloud and can function only on one server. The trouble with using a single machine is that in the event that one service crashes or generates high load, the whole server will almost certainly go offline, so your Internet sites will no longer be accessible.
