The observations that IT is managing the wrong things and that there is a lack of abstraction in the data center are the keys to solving the problems of cost, complexity, and lack of agility. The new abstraction model is the basis of the N1 Grid vision and a key driver for the N1 Grid architecture and products. The realization of this is that a data center is no longer managed in a component-centric fashion, but rather, is one that is service-centric. Services are what the business delivers and understands. Services are the things that are developed and deployed. Services are the way in which the data center delivers value, and services are what you should manage, not components.
This book describes new abstractions for managing data center infrastructure in a service-centric fashion, specifically those put forward by the N1 Grid vision and strategy. Applying these abstractions enables you to get the most from your infrastructure, while laying the foundation that enables you to take advantage of new technologies.
