DevOps is best defined as a philosophy or ideology. Many of the underlying principles and language of the DevOps philosophy are grounded in a combination of Agile software development plus Kaizen, Lean Manufacturing, and Six Sigma methodologies. The common goal of DevOps is to remove friction, risk, and other constraints to enable faster, more successful application production rollouts, as often and as rapidly as the business requires. Most companies that implement DevOps methods today still have a development team and an operations team in place. You can think of DevOps as the processes and individuals that build the bridges between these teams to improve the business and enhance the end-customer experience. Various tools and platforms facilitate the work of DevOps, but they do not define it.
