How is cloud computing different from grid and thin client?

In cloud computing, companies can store there information on the internet which is referred to as ‘cloud’ and therefore they pay only for what they use. These cuts on the amount the company would have spent on  buying more computers and other computing equipment that assist in storage of information, especially for small and medium-sized companies that require upgrading of their systems from time to time due to increase in the amount of data stored. The cost of buying hardware and software is cut when cloud computing is used.

Grid computing on the other hand involves the use many computers at the same time for the purpose of solving a single problem. The computers are meant to share resources so that to solve problems collaboratively. The computers on a grid may be located far away from each but on a network and they are also loosely coupled.

In thin client computing, users on the network gain access to their information via a network connection to a server. Users access information via the desktop, and the major disadvantage of this is that when the server goes down, then all the users on the network are affected.
