The conference was also technically co-sponsored by SINTEF and mOSAIC. The purpose of the CLOSER series of conferences is to bring together re- searchers, engineers, and practitioners interested in the emerging area of cloud computing. The conference has four main tracks, namely, “Cloud Computing Fundamentals,” “Services Science Foundation for Cloud Computing,” “Cloud ComputingPlatformsandApplications,”and“CloudComputingEnablingTech- nology.” In the last few years, cloud computing has expanded steadily, both horizontally across industries and vertically in organizations’ information tech- nology stack, for raw computing and storage, databases and system’s utilities, e-collaborative tools, and enterprise applications. Certainly cloud computing is a phenomenon grasping businesses and professional communities’ attentiveness invariousimportantdimensions.Cloudcomputingdevelopmentlikewisecreates exciting challenges and opportunities for scholars, developers, and IT experts. It is a thrilling journey driven by many agendas such as: cost cutbacks; better utilizationofexistingITinfrastructuresandsystems;anddesigning,developing, and delivering dynamic mobile and interactive computational services based on advanced provisional models. The immense economic demands in the last sev- eral years, in conjunction with the immediate reduction of upfront capital and operational costs when cloud-based services are employed, increase the speed and the scale of cloud computing creations and adoptions. While information and communication technology developments have en- abled the shift from manufacturing to service industries, this did not coincide with the emerging of an academic discipline that provided training and con- ducted research into the management and engineering of services from an in- tegrated perspective. Only a few years ago, the need for such a discipline was identified, and services science was established as a blending of, among others, computer science, engineering, management, and social science. Today the ser- vices sector already accounts for up to 80% of the economic activity in many developedcountries.Servicessciencecangroundthe developmentof“movingto the cloud” with a solid understanding of new cloud-based services, leading to knowledge on how they should be designed, deployed, and managed, and how they affect economy and society. With this linking, problems of diverse nature VI Preface can be identified and addressed in early stages, and opportunities can be more effectively exploited. CLOSER 2012 received 145 paper submissions from all continents. From these, 27 papers were published and presented as full papers, 44 were accepted for short presentation, and another 20 for poster presentation. These numbers, leading to a full-paper acceptance ratio of 19% and an oral paper acceptance ratio of 49%, show the intention of preserving a high-quality forum for this and next editions of the conference. The papers included in this book were selected from those with the best re- viewstakingalsointoaccountthequalityoftheirpresentationattheconference, asassessedbythesessionchairs.Wehopethatyoufindthesepapersinteresting, andwe trustthey representa helpful referenceforallthose whoneedtoaddress any of the research areas mentioned above.
