Server hardware is reduced and thus power. Storage can be centralised whether it is physical or virtual. Networking can be as complex (multiple NICs on Hosts)

A & C
The initial motivator to move to virtualization was server consolidation. Server sprawl was a very big problem in the “1 app, 1 server” datacenter environment. Hundreds of servers were using power, generating heat, taking up space, and requiring administration. On top
of that, the great majority of these servers were woefully underutilized, using just a fraction of their CPU and memory. It was a completely inefficient way to run a datacenter. Virtualization allowed one physical server to be shared by multiple VMs. In the early days, you could get ratios of 20 to 1—this represented significant cost savings to the business. Over time, these ratios have grown, and it is not uncommon to see ratios of 100 to 1 now.
