Just published a translation of Deployment environment article on Russian Wikipedia .
I publish this translation here as well. Remarks and comments are welcome.
In software deployment , an environment or tier is a computer system in which a computer program or software component is deployed and executed. In the simple case, such a deployment and immediate execution of the program on the same machine can be performed in a single environment, however, in industrial development, the separation of the development environment ('developer environment') (where the initial changes are made) and production is usedenvironment (which end users use); often with intermediate stages ('stages') in the middle. This structured release management process can have phases for deployment (rollout, rollout, rollout), testing (rollout), and rollback in case of problems.

Develpment, Staging, and Production are well-known and documented environment variables in ASP.NET Core . Depending on the specified variable, different code and different content rendering are performed, different security and debugging settings are applied.
