Operate by the numbers.

How many VMs fit on a host while balancing cost and performance? Model ESXi capacity, size your Gold/Silver/Bronze classes, set a VM mix, and read planned consumption across the allocation, reservation and utilisation models.

Take the public-cloud price as the ceiling, halve it for your budget, and see the private-cloud cost per host, VMs per box, and the potential savings at scale: the cloud-repatriation business case.
