Item A Model Driven Approach for Supporting the Cloud Target Selection Process(2015) Kopaneli, Aliki; Kousiouris, George; Velez, Gorka Echevarria; Evangelinou, Athanasia; Varvarigou, Theodora; Tecnalia Research & InnovationThe decision making process for the selection of one cloud target over another plays a major role during the migration to the Cloud, affecting not only the operational costs, functional characteristics and QoS, but also the development, monitoring and maintaining experience of the IT professionals. As the Cloud gains ground, a progressively growing number of cloud providers, services and technologies are exposed in the market rendering the research and selection upon them complex and time consuming. Proposed efforts for automatic support, fail to follow the quick paste of evolution, demanding, thus, even more effort for maintaining the supporting systems. In this paper the Cloud Target Selection (CTS) tool methodology and prototype implementation are presented introducing a novel approach: The CloudML@artist modeling language is exploited as a representation of real-world cloud environments becoming a source of information for an extensible decision making mechanism. The proposed work contributes in the direction towards the construction of an adaptive solution, which will follow the technological advances requiring the minimum of human intervention.Item Sky computing platform for legacy distributed application(2012) Panica, Silviu; Petcu, Dana; Larrate, Iñigo Lazkanotegi; Máhr, Tamás; SGThe elasticity and scalability promised by the Cloud computing paradigm, intended mainly for the new Web 2.0 applications, attracts also legacy applications owners. The migration of legacy applications towards Cloud is a complex process and only few tools and platforms are available to assist the applications' owners in this process. This paper explains the challenges that arise in the migration process of legacy applications and also exposes the solution offered by an open-source platform as a service, named mOSAIC, designed to deal with applications portability between Clouds.Item Software Modernization Revisited: Challenges and Prospects(2015-08-01) Bruneliere, Hugo; Cabot, Jordi; Izquierdo, Javier Luis Canovas; Arrieta, Leire Orue Echevarria; Strauss, Oliver; Wimmer, Manuel; Tecnalia Research & InnovationThe authors discuss important factors to consider when migrating software to the cloud and offer recommendations to maximize the chance of success.
