The Big Switch: Rewiring the World, from Edison to Google

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.

The Agile Architecture Revolution: How Cloud Computing, REST-based SOA, and Mobile Computing are Changing Enterprise IT

A sneak peek at up–and–coming trends in IT, a multidimensional vision for achieving business agility through agile architectures The Agile Architecture Revolution places IT trends into the context of Enterprise Architecture, reinventing Enterprise Architecture to support continuous business transformation. It focuses on the challenges of large organizations, while placing such organizations into the broader business ecosystem that includes small and midsize organizations as well as startups. Organizes the important trends that are facing technology in businesses and public sector organizations today and over the next several years Presents the five broad organizing principles called Supertrends: location independence, global cubicle, democratization of technology, deep interoperability, and complex systems engineering Provides a new perspective on service–oriented architecture in conjunction with architectural approaches to cloud computing and mobile technologies that explain how organizations can achieve better business visibility through IT and enterprise architecture Laying out a multidimensional vision for achieving agile architectures, this book discusses the crisis points that promise sudden, transformative change, unraveling how organizations spending on IT will continue to undergo radical change over the next ten years.

The Complex Adaptive Architecture Method

This article proposes a Complex Adaptive Architecture (CAA) method to architect an organic enterprise. It presents a complicated concept in a simple 3×3 matrix bonded by three architecture theories and a three-tiered architecture approach. CAA recognizes that SOA and Cloud Computing is a horizontal architecture practice which cannot be accomplished with the traditional top-down approach. The horizontal architecture consists of the discipline of learning from the experience of others, the discipline of engineering of re-use and consolidation, and the discipline to facilitate buy-in from stakeholders. CAA also discovers that the business community is making decisions based on influence relation rather than structural relation. Coherence Architecture theory is based on enterprise influence modeling and coherence modeling for the purpose of supporting enterprise strategic planning and decision-making. The Coherence Architecture consists of the discipline of influence modeling and the discipline of analogical reasoning. CAA embraces continuous change with a three-tiered architecture approach. The initial tier is the Notional Architecture which serves much like a master plan in city planning. The second tier is the Segment Architecture to close the business performance gaps due to change. The third tier is the daily Enterprise Architecture (EA) to enable an agile solution architecture.
