Merely storing your stuff online is not cloud computing

Cloud computing is a far more interesting and far reaching shift than the ability to store your stuff ‘out there’. I think the fundamental principle that defines cloud computing is on-demand resource provisioning. Whether it’s storage or computing power, it means that startups no longer have to spend money up front on data centers. It means that enterprises can save tons of money by not having servers out there idling and burning cash.
And even though there are detractors who will say “cloud computing is grid technology rebranded with a new buzzword”, they are just like the people who said “AJAX is DHTML and we had it in the 90s”. These people are missing the point. Having terminology to describe a phenomenon is a Good Thing. It enables us to easily refer to it and build on top of it. But let’s make sure we understand what’s happening before we apply this new buzzword to every online service under the sun, because then we’re limiting its usefulness.
