Size Guidelines

This section lists resource requirements for Palette for various capacity levels. In Palette VerteX, the terms small, medium, and large are used to describe the instance size of worker pools that Palette is installed on. The following table lists the resource requirements for each size.


The recommended maximum number of deployed nodes and clusters in the environment should not be exceeded. We have tested the performance of Palette with the recommended maximum number of deployed nodes and clusters. Exceeding these limits can negatively impact performance and result in instability. The active workload limit refers to the maximum number of active nodes and pods at any given time.
