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.

Components of OpenStack

OpenStack is an Infrastructure as a Service (IaaS) platform that is composed of several individual components or projects. These individual components communicate with each other using an application programming interface(API). This makes it possible to install these components on either a single machine or several machines connected to each other on IP layer.

These individual components have already been briefly discussed in Chapter 1, Getting Started with the Orchestration Service for OpenStack; therefore, we will not repeat them again in this chapter. However, we will explain how these components can be integrated with each other using OpenStack API and IP connectivity.

The following diagram shows the main components of OpenStack installed on the three nodes:
