OpenStack Orchestration

By: Adnan Ahmed Siddiqui

Overview of this book

This book is focused on setting up and using one of the most important services in OpenStack orchestration, Heat. First, the book introduces you to the orchestration service for OpenStack to help you understand the uses of the templating mechanism, complex control groups of cloud resources, and huge-potential and multiple-use cases. We then move on to the topology and orchestration specification for cloud applications and standards, before introducing the most popular IaaS cloud framework, Heat. You will get to grips with the standards used in Heat, overview and roadmap, architecture and CLI, heat API, heat engine, CloudWatch API, scaling principles, JeOS and installation and configuration of Heat. We wrap up by giving you some insights into troubleshooting for OpenStack. With easy-to-follow, step-by-step instructions and supporting images, you will be able to manage OpenStack operations by implementing the orchestration services of Heat.

In this chapter, we learned about the detailed OpenStack architecture. Heat is an important component of OpenStack and provides orchestration services for deploying OpenStack services in an ordered manner. We discussed the OpenStack node types, including controller node, compute node, network node, storage node, and other utility nodes. We discussed that a simple OpenStack solution may contain a single physical machine with a single NIC at minimum; however, this can be useful for educational or testing purposes only. We also discussed that in a production environment, each of the OpenStack node types can be installed on a separate physical machine or even more than one machines. We also discussed a three-node OpenStack architecture composed of one controller/networking node and two compute nodes. In a later section of the chapter, we explained two example architectures. The first architecture used the legacy networking in OpenStack, which is also known as Nova networking. In the...
