Hypervisors and Virtualization Basics
Gain insight into the fundamental concepts of hardware virtualization, how hypervisors work, and their interaction with the CPU.
What is Virtualization?
Imagine running multiple computers, each with its own operating system, all on a single physical machine. This powerful concept is called virtualization.
It allows you to share one computer's resources (like CPU, memory, storage) among several virtual environments.
Why We Virtualize
Virtualization offers many advantages, making it a cornerstone of modern computing:
- Server Consolidation: Run many servers on fewer physical machines, saving space and power.
- Resource Isolation: Each virtual machine (VM) is isolated, preventing issues in one from affecting others.
- Development & Testing: Create new environments quickly for software development and testing without impacting production systems.
- Security: Isolate potentially risky applications in a sandbox.
