In short
Virtualization uses software called a hypervisor to run several virtual machines, each with its own operating system, on one physical server. It is a foundation of cloud computing.
Key takeaways
- It uses hardware more efficiently and makes systems quick to copy and restore.
- A compromised hypervisor can expose every virtual machine on it.
- Unmanaged growth in virtual machines (sprawl) creates unpatched, forgotten systems.
