Review and analysis of networking challenges in cloud computing

Cloud Computing offers virtualized computing, storage, and networking resources, over the Internet, to organizations and individual users in a completely dynamic way. These cloud resources are cheaper, easier to manage, and more elastic than sets of local, physical, ones. This encourages customers to outsource their applications and services to the cloud. The migration of both data and applications outside the administrative domain of customers into a shared environment imposes transversal, functional problems across distinct platforms and technologies. This article provides a contemporary discussion of the most relevant functional problems associated with the current evolution of Cloud Computing, mainly from the network perspective. The paper also gives a concise description of Cloud Computing concepts and technologies. It starts with a brief history about cloud computing, tracing its roots. Then, architectural models of cloud services are described, and the most relevant products for Cloud Computing are briefly discussed along with a comprehensive literature review. The paper highlights and analyzes the most pertinent and practical network issues of relevance to the provision of high-assurance cloud services through the Internet, including security. Finally, trends and future research directions are also presented

An Economic Analysis of the Law Surrounding Data Aggregation in Cyberspace

The emergence of technological advances has traditionally created new and unique legal problems. The solutions to counter these problems are often drawn from our legal traditions and adapted to an ever-modernizing world. However, as Professor Coase opined at the dawn of the communication technology revolution, “lawyers and economists should not be so overwhelmed by the emergence of new technologies as to change the existing legal and economic system without first making quite certain that this is required.” Examination and reflection, in other words, is paramount to instituting a sound legal framework to encompass developing legal problems in technology. This Article seeks to address the developing legal problems associated with commercial data protection and gathering on the Internet. Although these problems were most recently addressed in two federal district cases, this Article will not deal with the details of those suits. Instead, this Article will seek to evaluate the rights of data “owners” and data aggregators through an economic analysis of possible legal regimes
