All the VMware Horizon components described in the preceding diagram are part of the overall Horizon solution, but, don't forget, some of the features available are dependent on which edition you have purchased.

It's also worth remembering that Horizon licensing includes the relevant vSphere components, ESXi hypervisor and vCenter Server licensing, to enable you to deploy the core hosting infrastructure. You can deploy as many ESXi hosts and vCenter servers as you require to host the desktop infrastructure.
