What is DevOps?

Ways of working that bring software development and operations together so software ships faster and more reliably.

In plain English

DevOps combines culture and practice: shared responsibility between developers and operations, automation of building, testing and deploying, and fast feedback from running systems. It is not a job title or a single tool. Common practices include continuous integration and delivery, infrastructure as code and monitoring.

Example

A change is merged, automatically tested, deployed and watched with dashboards, with the same team responsible for what happens in production.
