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.

Network layout for OpenStack networking

The network infrastructure includes all hardware devices involved in running the whole OpenStack solution, for example the switches, load balancers, servers, storage devices, and so on.

OpenStack uses several small network segments for establishing communication between different components. These network segments are described in the following sections.

The internal network

The internal network (as the name indicates) is used by the OpenStack components for communicating with each other for carrying out different functions, including provisioning of physical nodes, and communication between different node types using the OpenStack API.

The public network

The public network is used for accessing the Horizon interface of OpenStack and also for configuring floating IPs on the public facing interfaces of the virtual machine instances.

The OpenStack controller nodes are connected to this network so that the OpenStack Horizon interface can be accessed. It is...
