Part of the Cloud Computing Roadmap.

Summary

Conceptual layered models describing how network communication works, from physical cables up through applications — the shared vocabulary used constantly when discussing cloud networking components.

How to Learn This

  • 1Memorize the 7 OSI layers well enough to name them in order.
  • 2Learn which layer common cloud concepts (VPCs, load balancers, firewalls) primarily operate at.
