DevOps Training From Ducat

DevOps is a new term emerging from the collision of two major related trends. 1) The first was also called “agile system administration” or “agile operations”; it sprang from applying newer Agile and Lean approaches to operations work. 2)The second is a much expanded understanding of the value of collaboration between development and operations staff throughout all stages of the development lifecycle when creating and operating a service.DevOps is the union of people, process and products to enable the continuous delivery of value to end users. It aims to create a culture and environment where building, testing, and releasing software can happen rapidly, frequently, and more reliably, so you can innovate like a startup and scale for the enterprise
