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.

Chapter 3. Planning for Failure (and Success)

In this chapter, we'll be walking through how to architect your cloud to avoid hardware and software failures. The OpenStack control plane is comprised of web services, application services, database services, and a message bus. All of these tiers require different approaches to make them highly available and some organizations will already have defined architectures for each of the services. We've seen that customers either reuse those existing patterns or adopt new ones which are specific to the OpenStack platform. Both of these approaches make sense, depending on the scale of the deployment. Many successful deployments actually implement a blend of these.

For example, if your organization already has a supported pattern for highly available MySQL databases, you might chose that pattern instead of the one outlined in this chapter. If your organization doesn't have a pattern for highly available MongoDB, you might have to architect a new one...
