Item Empowering Services based Software in the Digital Single Market to Foster an Ecosystem of Trusted, Interoperable and Legally Compliant Cloud-Services(SciTePress, 2016) Alonso Ibarra, Juncal; Orue-Echevarria, Leire; Escalante, Marisa; Benguria, Gorka; Cardoso, Jorge; Cardoso, Jorge; Ferguson, Donald; Munoz, Victor Mendez; Helfert, Markus; Tecnalia Research & Innovation; HPA; CIBERSEC&DLTThe software industry has evolved from software on the shelf based applications deployed in dedicated servers , to Software as a service based components running on public or private Clouds and now to Cloud Service Brokers So, Cloud service brokerages have emerged as digital intermediaries in the information technology (IT) services market (Shang, 2013), creating value for cloud computing clients and vendors alike. This paper presents an approach to foster next generation cloud service brokers through an ecosystem of trusted, interoperable and legally compliant cloud services through an added value Cloud Services intermediator. This ecosystem will offer, create, consume and assess trusted, interoperable, and standard Cloud Services, where to (semi-)automatically deploy the next generation service based software applications.Item Federated Cloud Service Broker (FCSB): An Advanced Cloud Service Intermediator for Public Administrations(2017) Alonso Ibarra, Juncal; Orue-Echevarria, Leire; Escalante, Marisa; Benguria, Gorka; Echevarria, Gorka; Tecnalia Research & InnovationA 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 Service Level Agreement-based GDPR Compliance and Security assurance in (multi)Cloud-based systems(2019-06-01) Rios Velasco, Erkuden; Iturbe, Eider; Larrucea, Xabier; Rak, Massimiliano; Mallouli, Wissam; Dominiak, Jacek; Muntes, Victor; Matthews, Peter; Gonzalez Moctezuma, Luis; Gonzalez, Luis; Tecnalia Research & Innovation; CIBERSEC&DLTCompliance with the new European General Data Protection Regulation (Regulation (EU) 2016/679) and security assurance are currently two major challenges of Cloud-based systems. GDPR compliance implies both privacy and security mechanisms definition, enforcement and control, including evidence collection. This paper presents a novel DevOps framework aimed at supporting Cloud consumers in designing, deploying and operating (multi)Cloud systems that include the necessary privacy and security controls for ensuring transparency to end-users, third parties in service provision (if any) and law enforcement authorities. The framework relies on the risk-driven specification at design time of privacy and security level objectives in the system Service Level Agreement (SLA) and in their continuous monitoring and enforcement at runtime.
