The most misunderstood word in tech
Open any job board and you'll see hundreds of "DevOps Engineer" roles. Read the listings and they describe someone who knows Docker, Kubernetes, Terraform, and a CI/CD tool. So most beginners conclude DevOps is a job, a senior infrastructure person with a fancy title, or worse, a tool you can buy. Both are wrong, and believing either will quietly hold your career back.
DevOps is a way of working. It's a set of cultural habits and practices that get the people who write software and the people who operate it to behave like one team with one goal: ship valuable changes safely, quickly, and often. The tools are downstream of that idea. You can own every tool in the ecosystem and still not be doing DevOps. You can do DevOps with almost no tooling at all.
Note: Who this is for: Total beginners and career-switchers who keep hearing "DevOps" and want the real definition, not a tool list. If you've written any code or touched a server once, you have enough context. By the end you'll be able to explain DevOps to a hiring manager in a way that proves you actually get it.
