OpenStack Fundamentals

(5 days)

 

Course Description

Cloud computing is a major feature of the current IT landscape. Historically introduced to the world via proprietary cloud implementations such as Amazon Web Services and Google Cloud Platform, there is now significant interest in making the machinery of cloud computing universally available. This interest is being fueled by the availability of open source cloud computing infrastructure as a service (IaaS) frameworks such as OpenStack. Adopters of OpenStack find themselves dealing with issues common to all cutting edge technology: its novelty, complexity, and volatility present a certain amount of risk.

This course helps ease the adoption of OpenStack in the organization by guiding the attendees through its main features. The major OpenStack services including Keystone, Glance, Nova, and Neutron will be investigated including their use cases, architecture, and how they interoperate with each other. Networking is a major element in cloud computing. OpenStack supports a variety of networking technologies, including flat and GRE networking, which are explained in the course. Attendees will leave with a strong understanding of tenants, users, roles, and other domain-specific concepts. Participants will also learn and practice the steps for installing one service. Hands-on exercises are used to ensure a strong understanding of how to build and manage a Neutron virtual network. The Cielometer service which is used to measure the effectiveness of an OpenStack deployment will also be studied.

This course is aimed at the individual who must administer and extend the OpenStack framework. It will also be of interest to architects who want a detailed understanding of how OpenStack works and developers who are wanting a detailed overview before diving into the code.
