OpenStack High Availability Architecture

The Ubuntu OpenStack High Availability Architecture class is an add on to the OpenStack Fundamentals class. During this training, we will review High Availability concepts and services. After going over the key terms and concepts, we will look at using Juju to model High Availability in an OpenStack Cloud.

You will be able to compare Stateless and Stateful services and how this impacts your strategy for High Availability. You'll examine different tools and concepts for achieving high availability. Finally, you will go over techniques for extending your cloud's High Availability to your network tenants.
