DevOps is a way of working in software development where teams combine development (Dev) and operations (Ops) to build, test, and release software faster and more reliably. It focuses on collaboration between developers and IT operations teams to automate and streamline processes, improve efficiency, and ensure that software can be updated and deployed continuously with fewer errors.

In simple terms, it's like a bridge that helps developers and system administrators work together better, using tools and practices to make software delivery smoother and faster.
