7 Cloud Computing Myths Busted

What is it about "the cloud" that has people, well, getting their heads up in the clouds over it? Almost no other IT innovation in recent memory has engendered this much enthusiasm -- and furor, and confusion, and outright misunderstanding.
The cloud isn't exclusively a cure-all or a calamity in progress; neither is it a savior or sinner. It's a new tool for solving emergent problems, and like every new hammer in someone's hands it can make everything look like a nail.
In this piece we'll examine many of the current myths -- good, bad, and bogus -- about cloud computing. Many are borne by simple ignorance or inexperience. Others are legitimate criticisms in the guise of gripes. And some are entirely too on target, and need to be nipped in the bud by prospective cloud-creators before they get bitten by them.
Myths Unfolded
Myth 1: Cloud computing is too proprietary.
At present, no two clouds are alike -- both in nature and in IT.And yet "proprietary" has not proved to mean "useless" -- not by a long shot.
Myth 2: Cloud computing is the end of privacy as we know it.
Privacy fears over cloud computing can be seen as an outgrowth of privacy concerns in general, with cloud computing just being the bogeyman / whipping boy of the moment. That said, there's solid reasons to be skeptical -- or, if you're a creator of cloud-based services, to be cautious.
Myth 3: Cloud computing is not reliable.
File this one under "guilty until proven innocent." The cloud's been acquiring a leaden lining as of late -- a bad reputation for being questionably reliable.
Myth 4: Cloud computing is a one-way street.
Sadly, there's more than a grain of truth to the complaint that once you get things into the cloud, it's a chore and a half to get them out again.
Myth 5: Cloud computing is just virtual computing by another name. It's nothing we don't already have.
This objection seems more out of simple ignorance of what clouds are meant to do. Clouds aren't just fancy virtual computing environments -- they make use of virtual computing along with many other technologies to accomplish things that aren't possible with individual pieces of iron.
Myth 6: Cloud computing is too hidebound by network or storage constraints to be useful.
Well, yes and no. This depends entirely on the scale and scope of what you have in the cloud, how I/O bound it is, how scalable the processes involved are, and your chosen implementation for all of it.
Myth 7: It's too difficult to make use of the cloud's scalability.
This is a common complaint from the programmer's side: Cloud computing is hard to program for effectively. Sure, it's easy enough to get something up and running, but getting it to scale -- that's another story entirely. Ask the folks at Twitter, who started off their service as a Ruby on Rails application and are now incrementally rewriting the service.
