OpenStack Cloud

This course is designed for experienced Network Engineers that are interested in learning how OpenStack works with a specific focus on the networking aspects of how traffic flows across the environment. The course begins with a quick introduction to OpenStack via the web UI and progresses to networking concepts and configurations. Several traffic flow analysis scenarios are then discussed, each with a unique physical and logical layout. Comprehensive lab exercises are presented at the end of each unit for the students to work through. At the end of the course, the students will have a depth of knowledge about how to analyze existing OpenStack environments and configure new OpenStack environments with regards to existing data center network infrastructures.

Target Audience

  • Experienced Network Engineers with a desire to learn OpenStack Networking.

Prerequisites

  • A thorough understanding of Linux, Virtualization, routing, subnetting, and TCP/IP are required for this course. Further experience in using the Linux command line, REST APIs, and command line editors are highly beneficial.
