Based on my personal experience, I see that business in general thinks about retaining resources of all kinds (technical, financial, human, etc.) when and where they need it in order to optimize execution.
This is exactly why we are working to develop "Talent as a Service" for rationalizing your business' cloud journey. The age of addressing requirements over the entire deployment of technology with skill specific technical resources is coming to an end. Over the course of the deployment you will require different skills at different times. Most folks try to reduce the technical need to the term "DevOps" without having a specific definition of what skills encompass such a title. See the attached document and tell us what you think?
