An eye-opening look at the new computer revolution and the coming transformation of our economy, society, and culture.
A hundred years ago, companies stopped producing their own power with steam engines and generators and plugged into the newly built electric grid. The cheap power pumped out by electric utilities not only changed how businesses operated but also brought the modern world into existence. Today a similar revolution is under way. Companies are dismantling their private computer systems and tapping into rich services delivered over the Internet. This time it's computing that's turning into a utility. The shift is already remaking the computer industry, bringing new competitors like Google to the fore and threatening traditional stalwarts like Microsoft and Dell. But the effects will reach much further. Cheap computing will ultimately change society as profoundly as cheap electricity did. In this lucid and compelling book, Nicholas Carr weaves together history, economics, and technology to explain why computing is changing—and what it means for all of us.
Beyond the Net, say Foster, Kesselman, and a host of impressive contributors, lies the Grid. While the Net allows users everywhere to share information, the Grid will allow users to share raw computing power. The goal is to put full supercomputing capabilities into the hands of anyone who needs it while providing for more efficient use of the supercomputers of tomorrow. The potential benefits to science, government, and business may well be beyond imagination. (Book)

Grid Resource Management: State of the Art and Future Trends presents an overview of the state of the field and describes both the real experiences and the current research available today. Grid computing is a rapidly developing and changing field, involving the shared and coordinated use of dynamic, multi-institutional resources. Grid resource management is the process of identifying requirements, matching resources to applications, allocating those resources, and scheduling and monitoring Grid resources over time in order to run Grid applications as efficiently as possible. While Grids have become almost commonplace, the use of good Grid resource management tools is far from ubiquitous because of the many open issues of the field, including the multiple layers of schedulers, the lack of control over resources, the fact that resources are shared, and that users and administrators have conflicting performance goals. These are the issues addressed in this book, in addition to elucidating the overlap with related areas including discussions of work with peer-to-peer computing, economic approaches, and operations research. Grid Resource Management: State of the Art and Future Trends is an invaluable resource for today's user, application developer, or resource owners when working with Grid resource management systems.
Grid Computing: A Practical Guide to Technology and Applications (Programming Series) (Paperback)
by Ahmar Abbas
Grid computing takes collective advantage of the vast improvements in micro-processor speeds, optical communications, raw storage capacity, the World Wide Web, and the Internet that have occurred over the last five years. A set of standards and protocols are being developed that completely dis-aggregate current computer platforms and distribute them across a network as resources that can be called into action by any eligible user (person or machine) at any time. Grid computing is revolutionizing the way companies utilize information technology in business. This book provides IT professionals with a clear, readable, and pragmatic overview to all aspects of grid computing technology, with hands-on guidelines for implementing a workable grid computing system. Beginning with a thorough history of the technology, the book then delves into grid architecture, desktop grids, data grids, Open Grid Services Architecture, grid programming techniques, and much more. The last section of the book is devoted to creating industry-specific grid computing applications.

It is impossible to satisfy the infinite rapid-increasing requirements with finite addition of servers and bandwidth in the traditional VOD (Video-on-Demand) system. In this paper, we propose a novel hybrid Grid-type architecture to resolve this problem. By taking advantage of the large storage and the powerful processing capability in current client-side devices, user host serves both as a client and as a mini video server, and the system capability is enhanced due to the contribution of user hosts. This VOD system not only benefits from the secure and efficient organization in Grid computing, but also benefits from the flexibility and scalability in peer-to-peer models. In order to reach an optimal utility factor of system resources, an adaptive video delivery policy is implemented in this system. By cooperating with each other, the relevant servers can supply instantaneous video services for local users.
This is a book about enterprise integration using messaging. It does not document any particular technology or product. Rather, it is designed for developers and integrators using a variety of messaging products and technologies, such as Message-oriented middleware (MOM) and EAI suites offered by vendors such as IBM (WebSphere MQ Family), Microsoft (BizTalk), TIBCO, WebMethods, SeeBeyond, Vitria, and others. Java Message Service (JMS) implementations incorporated into commercial and open source J2EE application servers as well as standalone products. Microsoft's Message Queuing (MSMQ), accessible through several APIs, including the System.Messaging libraries in Microsoft .NET. Emerging Web services standards that support asynchronous Web services (for example, WS-ReliableMessaging) and the associated APIs such as Sun Microsystems' Java API for XML Messaging (JAXM) or Microsoft's Web Services Extensions (WSE). Enterprise integration goes beyond creating a single application with a distributed n -tier architecture, which enables a single application to be distributed across several computers. Whereas one tier in a distributed application cannot run by itself, integrated applications are independent programs that can each run by themselves, yet that function by coordinating with each other in a loosely coupled way.
A resilient storage network is an environment where data is always available for the needs of the business.

Storage networks can be of various sizes, shapes, and technologies. This book shows you how to implement a resilient storage network infrastructure using different technologies including ATM, DWDM, FCIP, Fibre Channel, FICON, iFCP, InfiniBand, IP, iSCSI, Life Cycle Management, NAS, Object Based Storage, RAID, RDMA, Remote Mirroring, Replication, SAN, SCSI, SMI-S, SONET/SDH, Storage Services, Tape, Virtualization, and Volume Managers.
Information Technology (IT) has transformed itself from a source of competitive advantage to simply being a cost of doing business.
Despite the spectacular gains during the past 50 years, says Nicholas G. Carr, a former Harvard Business Review executive editor, IT will distinguish no single competitor. This contradicts many executives' perception that IT ubiquity is an advantage. They miss the point the scarcity, not ubiquity, creates an advantage.
IT's core functions - the storage, distribution and processing of data - are available to all. Without differentiation IT is relegated to commodity status. This should force executives to re-think their IT spending plans and their vendor relationships. As this perception gains acceptance, risk and cost control will become more important than investments in innovation. In short, technology is headed down the same path the steam engine, railroad and electricity followed. Only by becoming a shared and standardized resource will IT deliver its maximum social and economic potential.
If you consider yourself a grid expert (or want to become one), then consider reading the articles in the March 2005 version of IEEE Proceedings on Grid Computing, several of which were written by OGF leaders and by participants in the OGF.

Traditionally, information provided to warfighters only gave them broadsituational awareness. Today, information from sensors and databases can help warfighters target past what they can see. This has prompted the Department of Defense (DoD) to build a military analog to the Internet, to be a font of warfighting information (and system services). But how should responsibility for providing information and services be sharedbetween global external sources and organic local sources?
Performance Analysis and Grid Computing comprises selected contributions encapsulating this scientifically rich event. The articles are organized in three parts: Performance Modeling and Analysis, Performance Tools and Systems, and Grid Performance and Applications. It will provide invaluable reading for researchers and developers in the areas of performance analysis, high-end computer systems, and Grid computing.
High Performance Computing (HPC) is the area of supercomputers, the fastest and best systems of their time. Most supercomputers are used to solve scientific problems, be it weather forecasting, simulation of car crashes or wind tunnels, modeling of proteins in bio-chemical research, or for simulation of atom-bomb tests. The book deals with systems that are in practical use for such application areas. In the first part, the history of supercomputers is described, and it is shown which properties and trends will remain in the future. The second part describes all aspects of High Performance Computing, from chip technology over computer and cluster architecture, up to software, algorithms, and applications. The third part explores the practice of HPC planning: system selection, benchmarks, acceptance tests, and implementation of HPC environments. Finally, the book closes with an outlook on current trends and visions like Grid Computing.
Netwar-like cyberwar-describes a new spectrum of conflict that is emerging in the wake of the information revolution. Netwar includes conflicts waged, on the one hand, by terrorists, criminals, gangs, and ethnic extremists; and by civil-society activists (such as cyber activists or WTO protestors) on the other. What distinguishes netwar is the networked organizational structure of its practitioners-with many groups actually being leaderless-and their quickness in coming together in swarming attacks. To confront this new type of conflict, it is crucial for governments, military, and law enforcement to begin networking themselves.

Large IT organizations increasingly face the challenge of integrating various web services, applications, and other technologies into a single network. The solution to finding a meaningful large-scale architecture that is capable of spanning a global enterprise appears to have been met in ESB, or Enterprise Service Bus. Rather than conform to the hub-and-spoke architecture of traditional enterprise application integration products, ESB provides a highly distributed approach to integration, with unique capabilities that allow individual departments or business units to build out their integration projects in incremental, digestible chunks, maintaining their own local control and autonomy, while still being able to connect together each integration project into a larger, more global integration fabric, or grid.
