What is one of the most important decisions infrastructure & operations (I&O) professionals face today? It's not whether to leverage the cloud or build a private cloud or even which cloud to use. The more important decision is which applications to place in the cloud, and sadly this decision isn't often made objectively. Application development & delivery professionals often decide on their own by bypassing IT. When the decision is made in the open with all parts of IT and the business invited to collaborate, emotion and bravado often rule the day. "SAP's a total pain and a bloated beast, let's move that to the cloud," one CIO said to his staff recently. His belief was if we can do that in the cloud it will prove to the organization that we can move anything to the cloud. Sadly, while a big bang certainly would garner a lot of attention, the likelihood that this transition would be successful is extremely low, and a big bang effort that becomes a big disaster could sour your organization on the cloud and destroy IT's credibility. Instead, organizations should start with low risk applications that let you learn safely how to best leverage the cloud — whether public or private.
