Step 0
� Level 0 — Virtualization fundamentals
Start with the real basics: what a hypervisor does, how a VM differs from a physical machine, what snapshots are, how virtual networks work, and why storage performance matters. This step is less glamorous than cloud buzzwords, but it is where real infrastructure understanding begins.

Goal: Understand how virtualized environments actually behave.
Reality check
Many beginners treat virtualization as just 'running another computer inside a computer'. In real infrastructure, resource allocation, storage, networking, and recovery decisions matter a lot.
Common mistakes
- • Thinking snapshots are the same as backups
- • Ignoring storage performance
- • Allocating CPU and RAM randomly
- • Skipping virtual networking fundamentals
What you can realistically achieve
- • Understand what a hypervisor actually does
- • Recognize the difference between VM, host, storage, and network layers
- • Prepare for VMware or Microsoft virtualization with fewer gaps
