In a Qlik Sense setup, which environment is primarily used for user activity and interface?

The central node is primarily used for user activity and interface in a Qlik Sense setup. This environment serves as the key component where users interact with applications, conduct analytics, and access data through the user interface. It manages authentication, licensing, and load balancing for user requests, ensuring efficient resource utilization and prompt access to Qlik Sense applications.

In contrast, the other environments are designed for different purposes. The production node focuses on the delivery and processing of production-ready applications, while the consumer node is typically aimed at serving content to end users without the need for extensive resource utilization. The rim node, meanwhile, can facilitate additional processing capabilities or support scalability but does not directly engage in user interaction and interface tasks like the central node does.
