For the most part, enterprises understand that virtualization and automation are key components of a private cloud, but at what point does a virtualized environment become a private cloud? What can a private cloud offer that a virtualized environment can’t? How do you sell this idea internally? And how do you deliver a true private cloud in 2011?
In London, this March, I am facilitating a meeting of the Forrester Leadership Board Infrastructure & Operations Council, where we will tackle these very questions. If you are considering building a private cloud, there are changes you will need to make in your organization to get it right and our I&O council meeting will give you the opportunity to discuss this with other I&O leaders facing the same challenge.
Forrester took more than a thousand inquiries from clients on cloud computing in 2010, and one of the themes that kept coming up was about which applications they should plan to migrate to infrastructure-as-a-service (IaaS) cloud platforms. The answer: Wrong question.
What enterprises should really be thinking about is how they can take advantage of the economic model presented by cloud platforms with new applications. In fact, the majority of applications we find running on the leading cloud platforms aren't ones that migrated from the data center but ones that were built for the cloud.
A lot of the interest in migrating applications to cloud platforms stems from the belief that clouds are cheaper and therefore moving services to them is a good cost-saving tactic. And sure, public clouds bring economies of scale shared across multiple customers that are thus unachievable by nearly any enterprise. But those cost savings aren't simply passed down. Each public cloud is in the profit-making business and thus shares in the cost savings through margin capture.
For enterprises to make the most of a public cloud platform, they need to ensure that their applications match the economic model presented by public clouds. Otherwise, the cloud may actually cost you more. In our series of reports, "Justify Your Cloud Investment" we detail the sweet spot uses of public cloud platforms that fit these new economics and can help guide you towards these cost advantages.
