-Many factors, including hosted cluster workload and worker node count, affect how many hosted clusters can fit within a certain number of control-plane nodes. Use this sizing guide to help with hosted cluster capacity planning. This guidance assumes a highly available {hcp} topology. The load-based sizing examples were measured on a bare-metal cluster. Cloud-based instances might have different limiting factors, such as memory size.
