Overview of this book

Over the past six years, hundreds of organizations have successfully implemented Infrastructure as a Service (IaaS) platforms based on OpenStack. The huge amount of investment from these organizations, including industry giants such as IBM and HP, as well as open source leaders, such as Red Hat, Canonical, and SUSE, has led analysts to label OpenStack as the most important open source technology since the Linux operating system. Due to its ambitious scope, OpenStack is a complex and fast-evolving open source project that requires a diverse skill set to design and implement it. OpenStack for Architects leads you through the major decision points that you'll face while architecting an OpenStack private cloud for your organization. This book will address the recent changes made in the latest OpenStack release i.e Queens, and will also deal with advanced concepts such as containerization, NVF, and security. At each point, the authors offer you advice based on the experience they'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, the book focuses on ensuring that your OpenStack project meets the needs of your organization, which will guarantee a successful rollout.

OpenStack service specifics


In this section, we'll walk through each of the OpenStack services and outline the HA strategy for them. While most of the services can be configured as active/active behind a load balancer, some of them must be configured as active/passive and others may be configured as active/passive. Some of the configuration is dependent on a particular version of OpenStack as well, especially Ceilometer, Heat, and Neutron. The following details are current as of the Pike release of OpenStack.

OpenStack web services

As a general rule, all of the web services and the Horizon dashboard may be run active/active. These include the API services for Keystone, Glance, Nova, Cinder, Neutron, Heat, and Ceilometer. The scheduling services for Nova, Cinder, Neutron, Heat, and Ceilometer may also be deployed active/active. These services do not require a load balancer, as they respond to requests on the message bus.
