A cloud Internet hosting service means that each and every part of your world-wide web presence will be taken care of by an independent server. For instance, your files and databases will be handled by separate machines and since just a single type of processes will run on a server, each machine will perform better and will use its system resources to the fullest. Whether you will get a genuine cloud service or not also depends on the CP that you'll use to manage your account. Since most control panels were intended to function on a single server, they cannot work on a cloud platform regardless of what a given Internet hosting provider could advertise. In the event that one service stops responding, the whole server can go offline, so your websites will not be accessible. This is the reason why you should check what service you'll actually receive in case you are looking for cloud internet hosting before you buy anything.
