A Cloud Computing Example

Can you give me an example of  the advantages of cloud computing over desktop computing?  Why, for example, would I want to create a Google Doc file in the cloud rather than a Word Document on my computer?

Suppose you had a Word Document on your computer and, just to play around, you uploaded that document to Google Docs. If you flew from your East Coast home to Los Angeles to visit with a friend, you’d see the cloud advantage (once your flight finally left the ground).  The Google Doc file is available from your friend’s computer (PC, Mac, Linux).  Your Word file is still sitting on your PC at home, completely useless to you in LA.

Your friend, who is looking over your shoulder, says, “That document is pretty good, but it needs to be polished.  Too much use of the passive voice, too many pronouns with indefinite antecedents”.  At this point you remember your friend majored in English.  “Let me have a go at it and I’ll fix it up”, says your friend.  So, you tell the cloud (Google Docs) to let your friend have access to the file as an editor so he can muck around with your prose.

You fly home (after another interminable wait at the airport) and pour a glass of wine, since those airport delays always leave you frazzled. You open your browser to your Google Docs account.  You notice that your document now reads like it was written by an English major and you’re delighted with the changes your friend made.  The only problem is that on the flight back (or was it while you were still on the tarmac waiting those two hours to take off?) you thought of one more thing that should be in the document.  So you type, “It has been established by him that the cost of raw materials for this project is much higher than it needs to be.”

You go to refill your wine glass and  when you return to look at what you just wrote, you find it now says, “Professor Johnston established that the cost of raw materials for this project is much too high”.  Once again your friend has polished your file.

And working in the cloud is free, right?      Right!
