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.

Containers and OpenStack


Now that we know what containers are, we can discuss how they are beginning to impact OpenStack, both in terms of architecture and workloads. First, we will discuss how containers are perfect for being run on OpenStack and how they can be operated in the tenant space using new and existing projects. Second, we will cover how several OpenStack distributions are using container technology to drive additional efficiency, resiliency, and high availability into the OpenStack control plane.

Docker on OpenStack

Why would anyone want to run Docker on OpenStack? First, OpenStack has built-in drivers for launching docker containers with the same method as VMs, using Nova. This driver has been around a long time and works very well. There's a lot to be said for having a single orchestration platform for containers, VMs, and bare metal. Even without launching the direct virtualization driver for Nova to create native Docker containers, users can simply provision VMs with images...
