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.

Updating the design document

In this chapter, we walked through the different approaches and considerations for achieving H/A and scalability in OpenStack deployments. As Cloud Architects, we need to decide on the correct approach for our deployment and then document it thoroughly so that it can be evaluated by the larger team in our organization.

Each of the major OpenStack vendors has a reference architecture for highly available deployments and these should be used as a starting point for the design. The design should then be integrated with the existing Enterprise Architecture and modified to ensure that best practices established by the various stakeholders within an organization are followed.

For example, Red Hat's highly available control plane uses the Galera extension to achieve Active/Active MariaDB services, but the database architects within an organization may only support Oracle's MySQL in an Active/Passive configuration. The Cloud Architect may choose to implement the database...
