The constant intensification of technological needs, combined with the market renewal generated an increase in requests for information services and, as a consequence, an increase of the number of servers used in the companies data centers. This phenomenon generated a sharp increase in costs for companies that, not always, a corresponding improvement in terms of effectiveness and efficiency. More recently, companies approached to virtualization as data storage technique. The result of this development has contributed to the introduction of a new type of technology: cloud computing. This tool represents an alternative of virtualization. It is a relocation and abstraction of computational resources, storage and content distribution and reachable over the network. More specifically, this tool leads to an increase of the storage capacity and processing possibilities, passing from a computation based on individual and independent machines, to a calculation model obtained on unified and centralized positions. This new technology leads to obtain greater flexibility, resource optimization and cost containment, but mainly introduces the "pay-as-you-go" (Ibrahim et al., 2011) (or the ability to pay for a measured service). It seems clear that in a context of crisis, in which the increase of the internal efficiency of enterprises necessarily passes by cost reduction, this tool, perceived as one of the key technologies of the 21st century by many authors (Buyya et al., 2004 and 2008; Sultan, 2010 and 2011; Marston et al., 2011; Kaiserswerth et al., 2012; Lee and Mautz, 2012), is able to offer many benefits to companies. Despite, cloud computing has a large number of risks that limit its implementation especially among small and medium enterprises (SMEs) which, according to numerous authors Lawler et al., 2012; Brender and Markov, 2013; Gupta et al., 2013; Mahmood et al., 2014 ; Oliveira et al., 2014; Son et al, 2014), would be the main beneficiaries of this technology. For this purpose, as well as agreements with the enterprise customer, this work focuses on the issue of the benefits and risks arising from the implementation of cloud computing within small and medium-sized Italian companies. The thesis consists of three chapters, organized as research articles, related yet independent in their structure.textFerri, LucaITIT-FI0098http://memoria.depositolegale.it/*/http://www.fedoa.unina.it/10115/1/Tesi%20dottorato%20cloud%20computing%20for%20italian%20SMEs%20benefits%20risks%20and%20open%20issues.pdfhttp://www.fedoa.unina.it/10115/1/Tesi%20dottorato%20cloud%20computing%20for%20italian%20SMEs%20benefits%20risks%20and%20open%20issues.pdfCFTDTD
