Too Long; Didn't Read
DevOps is the modern cycle of product development and delivery, which also includes its after-launch operation. The main purpose of DevOps’ existence is to fill the hole in the cycle of continuous integration, delivery, and operation of the product. The DevOps scheme presented by Atlassian back then is still relevant today. It’s better when DevOps led by someone with the admin background (but not the ‘any key’ specialist). An admin-led team is lower entry-level for an admin, so this means a faster start to a DevOps team.
