Which service is installed with the first instance of Backgrounder on a node?

The Non-Interactive Container Service is essential because it enables the execution of scheduled tasks and background jobs without requiring user interaction. When you install the first instance of Backgrounder on a node, the Non-Interactive Container Service is specifically designed to handle these background processing tasks effectively. This service runs the necessary processes and ensures that they can operate independently of user sessions, allowing for automation and more efficient resource management in a Tableau Server environment.

In contrast, the Interactive Container Service is primarily for tasks that require user interaction. The License Manager is a separate service dedicated to managing licenses rather than handling background processes. Site Import/Export serves a different purpose—allowing the movement of content between Tableau Server instances—and is not directly tied to the Backgrounder service during its initial setup. Therefore, the establishment of the Non-Interactive Container Service is a foundational step in ensuring that background tasks can be executed smoothly on the server.
