In the hosting field, cloud architecture refers to employing different servers for each service that is a part of the hosting service. In other words, your files, databases and emails will not run on the exact same machine, but on separate ones. Such a setup results in higher uptime and superior overall performance because only one type of system processes will run on the server, so the resources will be utilized as good as possible. Numerous companies these days 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 an individual server. If everything runs using one machine, an issue with just a single service can take the server offline. In this light, when you are looking for cloud hosting, you should check if the service you will receive is truly a cloud one or if it is a marketing trick.
