The Qlik Environment describes where the Qlik products are installed.
An environment is typically based on a server license and contains information about e.g. operating system, version number etc.
When creating the environment give it a name that makes sense to you, e.g. “My production environment”. Make sure to always review (and update as needed) the environment details when creating a case against it.
You can add other products to an environment, such as connectors.
An environment can be created/maintained here, or during the case creation process.
