DevOps Explained: How Modern Apps Get Built

Writing code is only half the story. Getting that code to run reliably for thousands of users is a craft of its own, and that craft is called DevOps.

Version Control

Tools like Git let teams work on the same project without overwriting each other, and let them undo mistakes by going back in time.

Automated Pipelines (CI/CD)

Every time code changes, a pipeline automatically tests it and, if everything passes, ships it to users. This catches bugs early and makes releases boring, in a good way.

Containers and the Cloud

Containers package an app with everything it needs so it runs the same on any computer. The cloud then runs those containers so the app can scale up when more people arrive.
