OpenStack for Architects - Second Edition

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.

Storage design


As compute hardware has become less expensive over the past few years, fewer and fewer workloads are constrained by a lack of processor or memory performance. Instead, most workloads are tuned so that they are constrained on I/O—particularly, storage I/O. OpenStack workloads typically separate the operating system storage from the application storage and Cinder, and the different object storage projects provide mechanisms to present many different kinds of storage with a single interface. This capability allows tenants to choose the storage that matches their application's requirements. In addition to Cinder providing persistence for applications, block storage and object storage also provide storage persistence for instances and allow instance live migration, backup, and recovery.

Ephemeral storage

Ephemeral storage is the storage that is consumed when a Glance image is copied locally to a compute node to instantiate a virtual instance. Glance images are typically sparse and...
