Cloud Computing is rapidly emerging as the new information technology platform. It is, however, much more than simply a new set of technologies and business models. Cloud Computing is transforming how consumers, companies, and governments store information, how they process that information, and how they utilize computing power. It can be an engine of innovation, a platform for entrepreneurship, and driver of corporate efficiency. While an increasingly commonly term, confusion remains over what exactly constitutes Cloud Computing, how the markets are unfolding, and what forces will drive their evolution and diffusion. This paper provides an overview and conceptual tools for business leaders, policymakers, and non-specialist scholars to identify, distill, and easily understand the core aspects of how Cloud Computing service markets are developing, and how an array of policy issues will influence how this new computing platform unfolds across the world.
We consider the vulnerability of nuclear power plants to a disaster like the one that occurred at Fukushima Daiichi. Examination of Japanese nuclear plants affected by the earthquake and tsunami on March 11, 2011 shows that three variables were crucial at the early stages of the crisis: plant elevation, sea wall elevation, and location and status of backup generators. Higher elevations for these variables, or waterproof protection of backup generators, could have mitigated or prevented the disaster. We collected information on these variables, along with historical data on run-up heights, for 89 coastal nuclear power plants in the world. The data shows that 1. Japanese plants were relatively unprotected against potential inundation in international comparison, but there was considerable variation for power plants within and outside of Japan; 2. Older power plants and plants owned by the largest utility companies appear to have been particularly unprotected.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
