7 Dumb Cloud Computing Myths

You've heard the arguments: The cloud is not secure, costs too much, and wrecks the environment. Let us set you straight.

As I leaf through the pages of my cloud scrapbook, I'm struck by how much valuable ink has been wasted repeating charges about cloud computing that just aren't true. Each year, sure as clockwork, Oracle CEO Larry Ellison tries to come up with a new putdownof the multi-tenant cloud during Oracle OpenWorld, like throwing mud against the wall to see if it sticks. Each year, the results are the same -- splat and slide, gravity beats FUD.

Let's start with security myths. I've long been interested in the supposed lack of security in the cloud and concluded that cloud operations are more secure than those of the average data center. That doesn't mean there aren't a lot of gaps and loopholes when it comes to sending your data over the Internet to cloud servers; any exposure to the public Internet contains its own hazards.

Data movement to the cloudis not a layup. But the standard of operations at Amazon Web Services, Terremark, Rackspace, Savvis and others is high enough that you can be assured of best practices on a more consistent basis than in many enterprise data centers. These centers are also going to be irresistible targets, and eventually an isolated breach will occur. Achieving security in the cloud is a journey that's just gotten underway.

I've also heard many critics say there's no definition of cloud computing, because there isn't really anything new to define. In fact, there is the NIST definition, but I'm inclined to say it's more description than definition.

The heart of cloud computing revolves around a new pattern of distributing computing power, not a new technology. In this new pattern, the end user has much more control than he used to over a powerful, remote server owned by somebody else. That control can extend up to the point where he achieves programmatic control over the server, if desired. Getting that control while engaging in one of the lowest-cost forms of computing is the heart of the cloud, an emerging relationship between the end user and publicly accessible data services.

The myths that are most difficult to bust are the ones involving cloud costs. There are many circumstances where monitoring cloud usage gets away from IT managers. They lose track of what employees have spun up; at the end of the month IT is presented with a big, surprising bill.

Before any cost comparison can be made, the cloud customer needs to know what specific operations in his own data center cost--a major research project. Some IT organizations do not have a true measure of total data center cost.

Explore my list of the top seven cloud myths that continue to bedevil prospective cloud users. Then weigh in with your opinion by leaving a comment.

re: 7 Dumb Cloud Computing Myths
Myth #7 "Nevertheless, scientists may one day conclude that global warming is producing larger hurricanes on the East Coast and extended droughts in the Midwest. At that point it's possible to see government deciding global warming threatens society's survival and future use of cloud data centers must be rationed, whether that's the right decision or not."

Um, a) I think about 99% of scientists would probably say that global warming is producing larger storms and greater droughts. Frustrating to see such articles geared toward a tech-savvy, fact-driven audience still presenting climate change as controversial (I'll cite Neil DeGrasse-Tyson, who, when asked if he believes in climate change, responds, "Do you believe in gravity?"). b) Not sure why the government would "ration" cloud data centers, seems more likely that taxes would increase on energy and businesses would have to decide whether it still made operational sense to use the cloud. Seems like an overly alarmist prediction!

Unfortunate choice of article format. Sorry, I can't use it - which means that I don't see you advertisers either. Your Nickel.

re: 7 Dumb Cloud Computing Myths
What a crock. Who is propagating these myths? No one. The problems with "the cloud" are real and undeniable. Local storage is more spacious, cheaper, faster, and physically smaller than ever. It's exactly the WRONG time to take all of your data and PAY to upload it to some third-party server, then PAY to get it back at crappy data rates while PAYING for the bandwidth and exhausting your data allowance.

Oh, and you can only get your data at the whim of that third party, and IF you have an Internet connection. So if you're lucky you MIGHT be able to get a bit of it on the plane. But not on that road trip through the mountains. Or the subway. Or in other countries, where you don't have a data plan. And on and on.

The people cheerleading for "the cloud" are shills or pathetically gullible.

re: 7 Dumb Cloud Computing Myths
I believe that the perception of Cloud risk has driven positive behavior in end users, making their non-Cloud activities safer. How many of your friends outside of IT knew what a VPN was two years ago, or file encryption? Because folks are scaring them about files they're copying to the Cloud, users are practicing safer computing in general.

Critic makes a fair point below. My ARM vocabulary failed me. ARM is a processor, not an operating system, but the ARM processor cannot use the x86 instruction set. The operating system must be ported to ARM, as Ubuntu has been.Most x86 OSs have not. Charlie Babcock, InformationWeek

re: 7 Dumb Cloud Computing Myths
A thought provoking list and analysis. Here's my tuppence worth:
The cloud is probably at least as secure, if not more secure than your remote/off-site data centre.
The VM spying issue is less of a concern than the inappropriate accessing of logs by physic server admins (at cloud, or your local farm - it's the people, stupid!).
The cost of the cloud services, like everything, is in the labour required to provide it (again - people).
Cloud shopping is more than just about price - find a service that suits, then negotiate price.
The choice of the OS will become less important (see previous comment) and diversity in OS will count for nothing in the longer term as energy costs will never be a long-term factor - see moore's law, and the comments about labour costs.
Open-source will eventually be monetised somehow - no such thing as a free lunch (there'll be ads in your data soup).
Cloud computing is eco-friendly, but online shopping is not - three trips by trucks to your house to delivery this weeks groceries vs the hybrid going to the mall - you can figure it out?
Great article, though - a new subscriber and enjoying what I see.

Also what does on line shopping have to do with cloud computing? The scenario would be the same weather Amazon had it's servers in the cloud or on site.

re: 7 Dumb Cloud Computing Myths
Actually, for myth #1, the cloud (like the internet) is *not* safe.

Many well-documented successful attacks have been carried out against PCI-compliant companies, the DOD, etc. For example:

1) Big-Box Breach: The Inside Story of Wal-MartGÇÖs Hacker Attack (http://www.wired.com/threatlev...

2) White House confirms cyberattack (http://www.politico.com/news/s...

Rather than giving companies a false sense of security, tell them that they are at risk, but that the cloud can be made "at least as safe as everything else"...
