A Qlik Sense site consists of the following types of nodes:
- A central node: This is the minimum configuration; a site always includes a central node
- Zero or more rim nodes: Used to increase capacity and resilience
As long as the nodes in a site meet the system requirements, the operating system on the nodes may differ.
A node in a Qlik Sense site runs a set of Qlik Sense services. By configuring which services to run on a node, it can be set up to perform a specific role (for example, as a proxy node or a reload node) within a site.
