Recently I was talking to someone about cloud computing, and I just wanted to reassure them that it was not really all that difficult. That at least as far as virtual machines are concerned, they are just computers running in software on other computers. And that the purpose of cloud computing is to save having too many computers.
And that a cloud management platform is useful so that you don't lose your computers running in computers, and so you can talk to your computers in computers, and so on.
