As someone who has been covering cloud computing since the dawn of Amazon’s Elastic Compute Cloud (EC2) I’m constantly in education mode about what is and isn’t cloud computing. To borrow an analogy from my Forrester colleague Ted Schadler’s keynote at last year’s IT Forum, the challenge is a lot like helping blind men discern an elephant through just the parts of the animal they can reach. One feels the trunk and declares it a cylindrical, yet hairy and warm snake. The other calls it a strong, tough and deeply rooted tree upon feeling its hind leg. Each examiner brings their own experience and context to the challenge as well as their own judgments, then leaps to the conclusion that best fits their desires.
