Cloud computing and with what it eat.

Cloud computing? Hmm... What comes in your mind when you hear "cloud" computing? Computing somewhere in the clouds where you can't see? Well, It's true that you cant see them but they are not in a clouds at all. The basic idea of "cloud" is to provide network access on demand to the  data networks, servers, storage, applications, services , which can be promptly granted and released with minimal operating costs and provider access. Sounds familiar isnt it? You could recognize the word "cloud" by the very popular now service called "Cloud Storage" such as Dropbox, Google Drive and etc. Idea of those is to provide users an internet storage which will allow users permanent(constant) access to their files they saved there before. This system works as on the diagram above.
