Look cloud computing is the practice of using a network of remote servers hosted on the Internet to store, manage, and process data, rather than a local server or a personal computer.
And only reason to use cloud is that, because some companies make some software which have no competition to other,and in this case,if company sell that software,company get only one time money and if company keep that software on cloud, and obviously company found their customer to use that software.
now Company earn every month and after some year company get more money,which they have to sell.
