I can totally understand as I prefer written material as well.

Public Cloud networking and security is evolving at lightning speed. A book will become obsolete before it even comes out whereas the video recordings allow us to continuously update the modules as needed.

The best thing closest to book is study material of self-paced material on our community site and labs for hands-on experience by launching the Aviatrix Controller.

You may also use this community-supported tool to launch the controller and small lab topology for your learning needs.
