Hypervisor 101: Server Virtualization Basics

Even in their most basic form, virtualization technologies have transformed the data center at the core: servers, storage, networks. Here we’ll look specifically at the hypervisor, a tried-and-true technology that made server multi-tenancy (the ability for a single server to run multiple computing workloads as though they were running on multiple servers) for years.

First, here are some basic things to understand about the modern hypervisor:

At a very high level, hypervisor technologies represent intelligent pieces of software that allow us to abstract hardware resources and create multi-tenant server capabilities. These virtual servers (or services) are software-based virtual machines, or VMs, accessing underlying physical resources of the server, sharing those resources with each other.
