Good post. Completely agree that DevOps is simply agile development, with the proper emphasis on the disciplined lean engineering practices - rather than the shiny bells and whistles that tools have. In that sense DevOps is just a new term to describe Agile since "Agile" was unfortunately co-opted by the consultants and vendors. I expect that within a few years the term DevOps will be so over used and adulterated that a new term will be needed again by the practitioners.
Also, I think that DevOps and Scrum have some fundamental compatibility issues. I highly recommend using Kanban and Continuous Delivery, rather than Scrum.
