The Certified OpenStack Administrator or COA is a practical based exam that you can sit through the Linux Foundation and OpenStack.org. The exam will test you on the fundamentals skills needed to run an OpenStack cloud and the guide from the Urban Penguin will step you through the objectives laid out for the exam. OpenStack heralds from the stable of the OpenStack Foundation and forms the services that make up your public or private cloud. A virtualization platform that can be used for internal or external clients to be able to provision their own virtual machine instances. In a private cloud this may make up an environment for you DevOps to test updates and configuration before deployment to live systems. In a public cloud instances can be provisioned by paying customers such as we see provisioned by many cloud providers. Working though the course or reading the guide you are gradually going to make you a little more acquainted with OpenStack. We will do this by means of installing OpenStack using the DevStack installer on Ubuntu 16.04. With the installation up and running we will take you through the core services that make up OpenStack. These include Keystone as the identity service, Nova as the compute engine and Neutron as the networking service. Combine these services with the Cinder Volume service and Glance Image Service. We have ourselves a good system. Adding HEAT and Swift makes it great.
