Unlike shared or dedicated hosting services that are based on one machine(web server), the cloud hosting uses the latest cloud computing technologies to make use of the power of multiple web servers that are connected and act as one. When hosted on the cloud your site will have much less downtime due to server maintenance of malfunction and it is also much easier to scale or handle peaks in visitors, since it can combine the processing power, storage and RAM of multiple machines.
Cloud hosting is a next generation hosting service that can be on pay as you use plan. This can save you money if you expect your site visitors to be uneven with peaks or you expect high traffic that a single machine would not be able to handle.
