1.1 Why do we need DevOps?
There is a real problem between two kinds of people who both care about the product:
- Developers — build features, fix bugs, write code.
- Operations — the people on the server side. They install packages, copy builds, open ports carefully, restart services, read logs, and keep production alive.
If developers only “finish code” and operations only “put something on the server” with no shared system, every release becomes an argument. That is why we need DevOps.
DevOps is not one product you buy. It is a way of working where the same people (or tightly linked teams) design, build, test, ship and watch the software. The goal is simple: small changes, often, with less drama.
| Old hand-off | DevOps-style flow |
|---|---|
| Big release every few months | Small releases many times a week |
| "Works on my laptop" | Same build artefact in every environment |
| Ops learns about change on deploy day | Ops and Dev share the pipeline and on-call notes |
| Blame after outage | Blameless fix + one prevention step |
