Virtualization was dominated by on-premises enterprise virtualization, and on-premises private clouds were the primary sourcing model for VMs offered as a service – for a few years. Certainly not true today. In 2011, roughly 3 percent of all virtual machines (VMs) were sourced in public cloud IaaS providers (mainly Amazon). That was also roughly equal […]

The elephant in the room is – everyone sees a different part of the elephant.
