In the Internet hosting field, cloud architecture describes employing different servers for each and every service that is a part of the hosting service. In other words, your files, databases and emails will not run on the same machine, but on separate ones. Such a configuration contributes to higher uptime and improved overall performance as only a single type of system processes will run on the server, so the resources will be utilized as efficiently as possible. Many companies these days promote their cloud services, but what they offer is not genuine cloud architecture for the reason that the Internet hosting control panels they use are not designed to function with anything different from an individual server. When everything runs using one machine, a trouble with just a single service can take the entire server offline. In this light, when you are searching for cloud hosting, you should check if the service you'll get is in fact a cloud one or if this is a marketing trick.
