Unlike ITIL, DevOps is more of a philosophy than a formal framework. DevOps, which is short for Collaboration between Development and Operations, arose as a movement within IT best practices when IT managers began to realize that something needed to be done to close the communications and collaboration gap between development groups and support operations staff.
