In my previous podcast I describe how to develop a Hybrid IT Strategy. This strategy will define the blueprint of your environment moving forward but it will not quantify the size of each environment. To do that you need to start from your application portfolio and understand which apps will be moved and where to. You will use the policies and principles agreed upon in the architecture to do that, but as most traditional environments are over-provisioned, you should not take the size of each environment for granted. To optimize your utilization of cloud, take the time to test what each application really needs before you do the actual migration. And look for ways to optimize your private cloud environment so you maximize the use of the physical boxes. Take a moment to listen how to do that.
