devops 概念的萌芽发展历程

1. Patrick Debois coined the term DevOps in 2009 while organizing the
   DevOpsDays conference in Belgium.

DevOps can be examined from the following overlapping perspectives:

1. Metrics and measurement view: This aspect addresses quality and
   testing and stresses shared incentives.
2. Process view: This aspect covers congruence and flow to gain fast
   feedback and set up a holistic process.
3. Technical view: This aspect discusses fast feedback through
   automation, particularly automatic releasing, specification by
   example, and infrastructure as code.
