DevOps is a way of working that combines the roles of software development and IT operations (also known as "ops"). It is designed to help organizations create and deliver software more quickly and efficiently, by bringing together the people and tools that are needed to develop, test, and deploy software.
DevOps is based on the idea of "continuous delivery," which means that software is developed and released in small increments, rather than waiting until it is fully finished before releasing it. This allows organizations to get new features and updates to their customers more quickly, and to respond more quickly to changing customer needs and preferences.
DevOps also involves collaboration between developers and IT operations staff, and the use of automation tools to streamline the process of developing and releasing software. By using DevOps practices, organizations can improve the speed, quality, and reliability of their software, and better meet the needs of their customers.
DevOps is the combination of cultural philosophies, practices, and tools that increases an organization's ability to deliver applications and services at high velocity: evolving and improving products at a faster pace than organizations using traditional software development and infrastructure management processes.
