a professor confused me.
he says a storage server doesnt act as cloud server. only a server which can execute some program or app acts as cloud server.is that right?
another prof says a cloud server doesn't share users date with users friends. for ex rapidshare which store documents does not share a user accounts data even if user wants to with another user of rapid share. i have taken ex of rapidshare as an example analogy for any application which has several users with their documents and friends list and with some of tis friends user wants to share dataWhat exactly is cloud computing?
Cloud computing, as I understand it, are systems that share resources in the computing environment, but are not restricted to single server and/or geographic location, and presenting it as a single service to the users. I think your professors are mostly correct, but they just need to elaborate more so you understand.
Yes, a storage server doesn't make a cloud. But several storage servers might. Take Google docs for example. Lets say you have two text files stored there, in Google Docs. One file could exist on a server in California, the other in Minnesota. The web interface could be run on a server in Dallas while the word processing application runs on a server in Chicago. All these different systems work together, but all you, the user, sees all this stuff just working in front of you on the webpage. This is cloud computing.
Hope this helpsWhat exactly is cloud computing?
