#6 in our series of 2009 predictions
2008 saw massive hype around the concept of a “private cloud,” roughly defined as a adopting the technology and practices from public cloud providers for a single company behind the firewall. “Private clouds are the future of corporate IT” declared Gartner. “Private Clouds Take Shape,” gushed InformationWeek, citing the funding of companies like Elastra and Parascale. “Get off my cloud” said eWeek, questioning the security of public cloud environments compared to private clouds.
Here’s the rub: Private clouds are just an expensive data center with a fancy name. We predict that 2009 will represent the rise and fall of this over-hyped concept. Of course, virtualization, service-oriented architectures, and open standards are all great things for every company operating a data center to consider. But all this talk about “private clouds” is a distraction from the real news: the vast majority of companies shouldn’t need to worry about operating any sort of data center anymore, cloud-like or not.
The idea that somehow companies can use “private cloud” technology to offer their employees web services similar to Google, Amazon, or salesforce.com will lead to massive disappointment. Here’s why:
- Private clouds are sub-scale: There’s a reason why most innovative cloud computing providers have their roots in powering consumer web technology—that’s where the numbers are. Very few corporate data centers will see anything close to the type of volume seen by these vendors. And volume drives cost—the world has yet to see a truly “at scale” data center.
- You can’t teach an old dog new tricks: What do you get when you move legacy applications as-is to a new and improved data center? Marginal improvements on your legacy applications. There’s only so much you can achieve without truly re-platforming your applications to a cloud infrastructure… you can’t teach an old dog new tricks. Now that’s not entirely fair…. You can certainly teach an old dog to be better behaved. But it’s still an old dog.
- On-premise does not equal secure: the biggest driver towards private clouds has been fear, uncertainty, and doubt about security. For many, it just feels more secure to have your data in a data center that you control. But is it? Unless your company spends more money and energy thinking about security than Amazon, Google, and Salesforce, the answer is probably “no.” (Read Craig Balding walk through “7 Technical Security Benefits of Cloud Computing”)
- There’s no secret sauce: There’s no simple set of tricks that an operator of a data center can borrow from Amazon or Google. These companies make their living operating the world’s largest data centers. They are constantly optimizing how they operate based on real-time performance feedback from millions of transactions. (check out this presentation from Jeff Barr and Peter Coffee at the Architecture and Integration Summit). Can other operators of data centers learn something from this experience? Of course. But the rate of innovation will never be the same—private data centers will always be many, many steps behind the cloud.
There’s also something very suspicious in all this discussion of private clouds…. private clouds are advocated mainly by companies who make their money from selling or operating data centers, and risk losing their shirts as real cloud computing drives more and more computing onto shared infrastructure. I understand why these companies are reluctant to embrace true cloud computing: Imagine being the junior partner in IBM Global Services pitching a client to develop an application on Amazon, Google, or Salesforce. Not only are you taking money out of the pocket of your colleagues in hardware and software….. you are also taking money out of the pocket of your colleagues in professional services, since integration and app development are so much easier using on-demand platforms.
That’s not to say that there’s no place for the technology behind private clouds. In certain cases where it simply isn’t an option to utilize a public cloud, this technology can have a significant impact. But those use cases are few and far between, and the benefits to be achieved are insignificant relative to the benefits of moving to a public cloud. Here’s who should be thinking about private clouds:
- Cloud Providers: This is an easy one… companies that plan on being in the business of providing cloud computing capabilities to others need to think about how to effective provide their own cloud. But we’d argue that very few companies actually need to be in this business (e.g., we believe most on-demand BI vendors should be running on public cloud infrastructure).
- Highly regulated industries: Government regulation will always lag behind commercial application of technology. There will inevitably be instances where nervous politicians or policy makers write up requirements that can only be met through a private cloud.
- Companies in the process of moving to a public cloud: Of course, no company of any significant size can move its IT infrastructure to the cloud all at once. In fact, Appirio specializes in helping companies figure out what the right first step is away from their on-premise infrastructure. For the IT infrastructure that hasn’t yet moved, it definitely makes sense to think about how to use “private cloud” technology. But that means the private cloud is a temporary stop-gap, not the “future of enterprise IT.”
Implications for customers.
Of course any customer with a data center should be thinking about how to use the technologies behind “private clouds” to improve their efficiency. But this should be a minor element of your long-term IT strategy. The most important thing any IT department can do in 2009 is chart out a thoughtful plan to migrate significant portions of your IT infrastructure to the public cloud. Don’t let “private clouds” be a distraction from that goal.
