DevOps is a set of practices that combines software development (Dev) and information-technology operations (Ops) to shorten the systems-development life cycle while delivering features, fixes, and updates frequently in close alignment with business objectives.

DevOps aims to establish a culture and environment where building, testing, and releasing software can happen rapidly, frequently, and more reliably. This is achieved through a combination of tools and processes such as continuous integration, continuous delivery, infrastructure as code, and monitoring and observability.

DevOps is not a specific tool or technology, but rather a way of thinking and working that emphasizes collaboration, automation, and continuous improvement. It is not a replacement for development or operations teams, but rather a way to bring these teams closer together and improve the way they work together.

DevOps is also not a one-time implementation, but rather a continuous process of learning and improvement. It requires organizations to constantly assess and optimize their processes and tools in order to deliver value to their customers more efficiently.
