What is the role of the Qlik Sense Proxy Service (QPS)?

The Qlik Sense Proxy Service (QPS) is essential for managing user interactions with the Qlik Sense environment. Its primary responsibilities include handling authentication, managing user sessions, and balancing the load across multiple instances of Qlik Sense services. As users connect to the Qlik Sense environment, QPS authenticates them, ensuring they have the necessary permissions to access the applications. Once authenticated, it establishes session management to maintain the state of the user's interaction within the environment.

Furthermore, load balancing is critical as it optimizes performance by distributing requests evenly across multiple Qlik Sense services, preventing any one service from becoming a bottleneck. This ensures a smooth and efficient user experience, allowing access to analytics without downtime or lag. All of these functions are vital for the operation and reliability of the Qlik Sense platform, which is why this choice accurately describes the role of the Qlik Sense Proxy Service.

In contrast, the other options refer to functionalities that are either handled by different services within Qlik Sense or are not primary responsibilities of the QPS. For instance, synchronization of licensing data, handling calculations, and scheduling reloads of applications are managed by other components in the Qlik Sense infrastructure.
