Appropriate for all courses in deploying or managing service-centric datacenters, architectures, and IT infrastructures, as well as many courses focused on emerging trends in enterprise information technology.

Students entering tomorrow's IT organizations will be called upon to dramatically increase efficiency, utilization, reliability and flexibility-while reducing cost, staff requirements, and complexity at the same time. A new generation of virtualized, service-centric IT architectures are emerging to address these challenges, with Sun's N1 architecture at the forefront. This book thoroughly explains Sun's N1 vision, strategy, architecture, and products, showing how N1 can address tomorrow's most urgent IT challenges. Next, it walks students through the entire process of preparing, architecting, and implementing data center infrastructure that realizes the N1 vision and drives unprecedented business value. Along the way, the authors demonstrate how to maximize strategic flexibility, while optimizing infrastructure, enterprise applications, and data centers. The book concludes with a start-to-finish case study of N1 implementation in one of the world's most demanding business and technical environments: that of a telecommunications service provider. Part of the highly respected Sun BluePrints Series.

Back Cover

The N1 Grid is Sun's vision, strategy, and architecture-and a set of products-that redefine the nature of data center computing. The N1 Grid architecture uses the network, physically and logically, as its fundamental organizing principle.

This book enables the reader to implement service-centric data center solutions through the use of N1 Grid-based principles and architectures, which are more efficient and flexible. It opens with an overview of how this approach evolved and then takes the reader through the process of preparing, architecting, and implementing N1 Grid-based solutions.
