In the Internet hosting field, cloud architecture means employing different servers for each service which is a part of the internet 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 since only a single type of system processes will work on the server, so the resources will be utilized as good as possible. A lot of web hosting service providers these days advertise their cloud services, but what they supply is not true cloud architecture for the reason that the web hosting control panels they use are not designed to function with anything different from an individual server. If everything is run on one machine, an issue with a single service could take the server offline. In this light, when you are searching for cloud hosting, you should check if the service you will receive is in fact a cloud one or whether this is a marketing trick.
