This document discusses the fundamentals of virtualization. It describes traditional computing versus a virtualized environment and the two types of hypervisors - type 1 runs directly on hardware while type 2 runs on a host OS. Features of virtualization include sharing resources transparently across VMs, live migration, centralized management, and high availability. Virtualization helps address server sprawl by allowing server consolidation ratios of 10-40 physical to virtual servers, reducing costs for power, cooling, space and hardware while improving operational efficiency and avoiding downtime through features like high availability.
