What services need to be running on a Central Node?

The Central Node is a critical component in the Qlik Sense architecture, and it is essential for coordinating and managing various services that facilitate the overall operation of the system. When addressing what services need to be operational on a Central Node, it is pivotal to note that the complete functionality and management of a Qlik Sense deployment align with having all the necessary services running.

For a Central Node, the required services include the Engine service, which handles the core analytical functions, the Repository service, essential for managing the configuration and persistent data across the entire Qlik Sense environment, the Proxy service, which manages user sessions and handles client requests, and the Scheduler service, responsible for executing tasks such as reloads and data refreshes on a defined schedule.

Having all these services active ensures that the Central Node can effectively manage user access, oversee data processing tasks, and maintain system health, thereby providing a cohesive experience across the platform. The integration of all these services is fundamental for the Central Node's role in maintaining the correct operation and performance of a Qlik Sense environment. Each service plays a vital role in this ecosystem, seamlessly working together to ensure smooth functionality.
