DevOps basics
Description
DevOps is a term emerging from the merger of two major related trends. The first is called “agile system administration” or “agile operations”. It sprang from applying newer Agile and Lean approaches to operations work. The second is a much more expanded understanding of the value of collaboration between development and operations staff throughout all the stages of the development lifecycle when creating and operating a service.
DevOps doesn’t differentiate between different sysadmin sub-disciplines – “Ops” is a blanket term for systems engineers, system administrators, operations staff, release engineers, DBAs, network engineers, security professionals, and various other subdisciplines and job titles. “Dev” is used as shorthand for developers in particular, but really in practice it is even wider and means “all the people involved in developing the product,” which can include Product, QA, and other kinds of disciplines.
This training covers major aspects of DevOps principles. The goal is to provide a thorough understanding of DevOps, at the same time covering some practical real-world examples and popular tools.
