Be prepared to either add more worker nodes or increase the size of existing worker nodes to add more CPU and RAM. As well, consider stronger CPUs which might have higher clock speeds, more cache and be more efficient. + ## What's included in the per user cost This document covers hosting cost and does not cover Total Cost of Ownership (TCO).
