Wondering whether anyone could advise as to the differences between these two products, from my understanding the difference is the latter allows control of more than 3 hosts. What I really wanted to know was, the (cool) features like chargeback and extended Application monitoring are they included in both versions or am I missing something....
Foundation has all of the features of regular VC but is limited to 3 host, that's all.
Chargeback and AppSpeed are separate products that are chargable whichever VC version you have.
VMware vCenter Server Standard includes the following additional features:
vSphere 6.5 Update 1 supports up to 4 ESX Hosts in vCenter Server Foundation: see http://www.virten.net/2017/07/whats-inside-vmware-vsphere-6-5-update-1/
