OpenStack for Architects

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.

Storage design

As compute hardware has become less expensive over the last 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 for presenting many different kinds of storage with a single interface. This capability allows tenants to choose the storage which 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 for 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...
