OpenStack is a leader in the cloud technology gold rush, as organizations of all stripes discover the increased flexibility and speed to market that self-service cloud and Infrastructure-as-a-Service (IaaS) provides. However, in order to reap those benefits, the cloud must be designed and architected properly. A well-architected cloud provides a stable IT environment that offers easy access to needed resources, usage-based expenses, extra capacity on demand, disaster recovery, and a secure environment. A well-architected cloud does not magically build itself. It requires careful consideration of a multitude of factors both technical and non-technical. There is no single architecture that is "right" for an OpenStack cloud deployment. OpenStack can be used for any number of different purposes, each with its own particular requirements and architectural peculiarities. This book is designed to examine some of the most common uses for OpenStack clouds (and some less common uses) and to provide knowledge and advice to help explain the issues that require consideration. These examples, coupled with a wealth of knowledge and advice will help an organization design and build a well-architected OpenStack cloud to fit its unique requirements.
