Overview of this book

OpenStack Open Source software is one of the most used cloud infrastructures to support software development and big data analysis. It is developed by a thriving community of individual developers from around the globe and backed by most of the leading players in the cloud space today. It is simple to implement, massively scalable, and can store a large pool of data and networking resources. OpenStack has a strong ecosystem that helps you provision your cloud storage needs. Add OpenStack's enterprise features to reduce the cost of your business. This book will show you the steps to build up a private cloud environment. At the beginning, you'll discover the uses of cloud services such as the identity service, image service, and compute service. You'll dive into Neutron, the OpenStack Networking service, and get your hands dirty with configuring ML2, networks, routers, and Distributed Virtual Routers. You’ll then gather more expert knowledge on OpenStack cloud computing by managing your cloud's security and migration. After that, we delve in to OpenStack Object storage and how to manage servers and work with objects, cluster, and storage functionalities. Also, as you go deeper into the realm of OpenStack, you'll learn practical examples of Block storage, LBaaS, and FWaaS: installation and configuration covered ground up. Finally, you will learn OpenStack dashboard, Ansible and Foreman, Keystone, and other interesting topics.

Using Heat to spin up instances

With Heat, we can create a wide variety of templates—from spinning up basic instances to creating complete environments for an application. In this section, we will show the basics of Heat by spinning up an instance, attaching it to an existing Neutron network, and assigning a floating IP to it. Heat templates, known as Heat Orchestration Templates (HOT) are Yet Another Markup Language (YAML) based files. The files describe the resources being used, the type and size of the instances, and the network an instance will be attached to, among other pieces of information required to run that environment.

In this section, we will show how to use a HOT file to spin up two web servers running Apache that are connected to a third instance running HA Proxy.

Getting ready

Ensure you are logged into a Ubuntu host that has access to our OpenStack environment on the 192.168.100.0/24 public network. This host will be used to run client tools against the OpenStack environment...
