I. Introduction
DevOps is a practice that aims at integrating software development and operation processes [1]. It is expected to reduce deployment cycles, improve the quality of software, and shorten the time to patch bugs. This helps to increase the frequency of deployments, which helps to service customers faster [2]. Organizations that practice DevOps can deploy software changes as fast as 500 times per day [3]. CA Technologies found that 1254 out of 1425 surveyed organizations (i.e., 88%) will adopt DevOps by 2020 [4].
