What DevOps is
DevOps joins building software and running it into one process. Code passes automated tests, builds the same way every time and reaches production by the same route. When something goes wrong, the change can be rolled back.
It is not a job title or a single tool. It is a set of habits: a release pipeline, infrastructure as code, monitoring and runbooks for when things fail.
Signs you need it
- One person deploys, by hand, preferably in the evening.
- Nobody knows how to undo a change that broke something.
- A server was configured once and nobody can rebuild it.
- Customers tell you about outages before monitoring does.
- The cloud bill grows and nobody can explain it.
Where to start
First the pipeline: every change goes through the same tests and the same release. Then a rollback that has been rehearsed, not just written down. Only after that containers, Kubernetes and the rest.
Order matters. Kubernetes without a repeatable release only moves the chaos somewhere new.
