An environment is defined as a full website or application stack containing everything the website or application needs to deliver features and content to users. This includes, but is not limited to, the following:

• A dedicated parcel of server space
• Memory
• A database
• An operating system
• Application services

Most developers who work with several environments use at least two different environments:

• A development environment, where new code can be created and tested.
• A production environment, where the live website and its data exist.

Web development projects should use at least two or more environments. For example, a third environment for staging can be useful for merging production data with newly developed code for extensive testing purposes.
