The evolution of infrastructure operations has been a long journey that is still ongoing, but the real game changer will come when developers control their own destinies. On the surface, it seems IT requirements are the catalyst for the evolution of infrastructure technologies.
IT serves at the will of developer productivity who have a more direct influence on business outcomes. No matter what the security argument is, if IT builds a walled garden around infrastructure, productivity will suffer and developers will leave.
Ideally, developers should have been given direct infrastructure access through an abstraction layer that automated the low-level provisioning details.
