Cloud computing as I understand is stored in cloud. There is no need to store data on servers and maintanence of the same with engineers are minimized. If any problem arises, the part data be taken from cloud, rectified and placed back again which can be in the form of software. There is no need to change the entire program as previously done when using servers.
Now a days, due to the inception of cloud computing, doing and performing things are becoming easier. Previously all the programs to be checked and written once again, whereas in cloud computing part may be modified and replaced. This takes less time helpful and more convenient.
