Environment
A subset of the IT infrastructure that is used for a particular purpose, such as development, testing, or production. Environments are isolated to prevent activities in one stage from affecting another.
Impact
Proper environment management minimizes risk. It allows you to break things safely in "Test" so you don't break them in "Prod."
Weinto take
We treat environments as disposable. In a cloud-native world, we don't fix a broken environment; we delete it and spin up a new one. This "Cattle, not Pets" mentality extends from servers to entire environments, ensuring that we never suffer from "configuration drift" rot.
