When it comes to Internet hosting, cloud architecture refers to using an individual server for each aspect of the Internet hosting service. Such a setup provides a lot better performance because one machine will be used just for file storage, a different one just for running databases, and so on, which means that different system processes will not run on the exact same machine. This will minimize the probability of system errors substantially and will allow your websites to operate faster, not mentioning the higher uptime. When you are looking for this type of service, you should double check that you will really receive it as numerous companies advertise cloud web hosting plans, but the control panels they use aren't designed to function in a true cloud and can operate only on a single server. The problem with using one machine is that in the event that one service crashes or generates high load, the entire server will most probably go offline, so your Internet sites will no longer be accessible.
