This 2-day course gives students an in-depth look at complex networking in OpenStack using Neutron. The objective is to teach the skills to design, optimize, and troubleshoot a scalable, extensible, and highly available network within an OpenStack environment. The students get extensive hands-on lab experience with the course topics in a dedicated, pre-built OpenStack environment. This course assists in preparing students to pass expert-level OpenStack certification exams. Note that the lecture material and labs cover the latest updates in Neutron that were introduced with the Kilo release.
