A cloud Internet hosting service means that each part of your world-wide web presence will be maintained by a different server. For instance, your files and databases will be managed by different machines and since just one type of processes will run on a server, every machine will perform better and will use its resources to the fullest. Whether you will get a real cloud service or not also depends on the control panel that you will use to manage your account. Because most control panels are designed to work on a single server, they cannot work on a cloud platform whatever a given hosting service provider may advertise. If one service stops responding, the entire server can go offline, so your Internet sites won't be accessible. This is the reason why you should check what service you will actually receive if you are looking for cloud hosting before you buy anything.
