OpenStack for Architects

By: Michael Solberg, Benjamin Silverman

Overview of this book

Over the last five years, hundreds of organizations have successfully implemented Infrastructure as a Service (IaaS) platforms based on OpenStack. The huge amount of investment from these organizations, industry giants such as IBM and HP, as well as open source leaders such as Red Hat have led analysts to label OpenStack as the most important open source technology since the Linux operating system. Because of its ambitious scope, OpenStack is a complex and fast-evolving open source project that requires a diverse skill-set to design and implement it. This guide leads you through each of the major decision points that you'll face while architecting an OpenStack private cloud for your organization. At each point, we offer you advice based on the experience we've gained from designing and leading successful OpenStack projects in a wide range of industries. Each chapter also includes lab material that gives you a chance to install and configure the technologies used to build production-quality OpenStack clouds. Most importantly, we focus on ensuring that your OpenStack project meets the needs of your organization, which will guarantee a successful rollout.

Implementing H/A in the lab deployment

In this last section, we'll make the current lab deployment that we deployed in Chapter 2, Architecting the Cloud, highly available by adding a second controller node and configuring cluster software. This example should be simple enough to easily implement in the lab while still allowing you to evaluate the technology.

Provisioning a second controller

In later chapters we'll look at more flexible deployment methodologies that allow fine-grained service placement and automated cluster configuration. In this chapter, we'll just extend the Packstack deployment from Chapter 2, Architecting the Cloud. Packstack isn't designed to deploy multiple controllers, so some manual configuration of services will be required.

To provision the second controller, install the operating system on a new machine in the same way you provisioned the first controller and then copy the Packstack answer file from the first controller. Edit the answer and replace CONFIG_CONTROLLER_HOST...
