Item Federated cloud service broker (FCSB): An advanced cloud service intermediator for public administrations(SciTePress, 2017) Ibarra, Juncal Alonso; Orue-Echevarria, Leire; Escalante, Marisa; Benguria, Gorka; Echevarria, Gorka; Cardoso, Jorge; Munoz, Victor Mendez; Pahl, Claus; Cardoso, Jorge; Helfert, Markus; Ferguson, Donald; HPA; Tecnalia Research & Innovation; CIBERSEC&DLTA cloud services brokerage is third-party software that adds value to cloud services on behalf of cloud service consumers. Their goal is to make the services more specific to a company, or to integrate or aggregate services, to enhance their security, or to do anything which adds a significant layer of value (i.e. capabilities) to the original cloud services being offered (Plummer, 2012). There exist several solutions focused on providing service brokerage of Cloud Service Providers (CSP), mainly VM's and virtualized resources, but not of other services offered (e.g. Data Processing as a Service) or SaaS applications which are certified and legally compliant. This paper proposes a solution for a Federated Cloud Service Broker (FCSB) overcoming existing challenges in the public sector such as Governance, Interoperability and portability, SLAs compliance and assessment, Intelligent discovery of cloud services, cross border interoperability and legislation awareness . The analysis of the existing solutions, and the presentation of the approach made in (Alonso, et al., 2016) is complemented with a technical design including the main functionalities and the modules that will implement them.Item From software-AS-A-GOOD TO SAAS: Challenges and needs: Developing a tool supported methodology for the migration of non-saas applications to SaaS(2011) Arrieta, Leire Orue Echevarria; Ibarra, Juncal Alonso; Jan, Gottschick; Restel, Hannes; Tecnalia Research & Innovation; HPAFor all software vendors, but especially small and medium ones and in the current downturn economic situation with such a high competition, businesses that are not prepared to migrate the offerings of their software solutions to the form of online-services not only miss the opportunity to acquire new customers but they also run the risk of losing their existing customers towards new competitors. This transition from a software-as-a-good approach to a software-as-a-service one, is not trivial at all, and there exists a real demand for proven methods to perform the transition from traditional software products to the service concept. Based on this premise, the objective of this position paper is to provide software organizations with a stepwise procedure, methods and tools to migrate non-SaaS applications into SaaS, taking into account not only technical and technological issues but also issues related to business models and how to monetize the final solution. The solution presented here is a theoretical approach that is currently being validated in eight use cases in the Basque Country.
