About this track

This track teaches virtual machines from first principles through production operations. You will learn hypervisors, CPU and memory virtualization, virtual disks, networking, templates, observability, and hardening with hands-on Python exercises and practical architecture thinking.

Before you start
  • No prior virtualization experience is required.
  • Basic comfort reading simple Python code is helpful.
  • A modern browser with JavaScript enabled.
  • Python exercises run in-browser with the same runtime used by other Python learning tracks.
