In the Internet hosting field, cloud architecture identifies using different web servers for each service which is a part of the hosting service. In other words, your files, databases and e-mails will not run on the very same machine, but on separate ones. Such a setup results in higher uptime and much better overall performance because only one kind of system processes will run on the server, so the system resources will be utilized as well as possible. Numerous service providers nowadays promote their cloud services, but what they provide is not genuine cloud architecture for the simple reason that the web hosting control panels they use are not designed to operate with anything different from a single server. When everything runs on one machine, a trouble with just a single service may take the entire server offline. In this light, when you are looking for cloud hosting, you should check if the service you will receive is in fact a cloud one or if this is a marketing trick.
