Early on , in 2009 ,as I explored( as everybody did) cloud computing, I recognized it as a variation of / enabling an enterprise SOA. The overwhelming market discussion,however,was infrastructure led. It still is. Cloud is still seen as an infrastructure deployment strategy . Quite possibly, it might be the most commonly leveraged aspect and as we saw with the original SOA movement, there may be a shying away due to potential program costs .But service orientation is a fundamental under-pinning of cloud led architectures. My own view is captured schematically below. For cloud to deliver operating efficiency , it needs to overlay an information architecture that supports service orientation.
Can we develop a simplified ROI model that captures this proposed efficiency gain?A topic to explore in a later post.
