Cloud for Europe (C4E) is a project that aims at creating new Cloud workflows, named Service Flow (SF), for Public Administrations (PAs). These Services must guarantees on one hand to preserve national authorities, and on the other hand to promote efficiency, collaboration and harmonization for European PA bodies. This is possible by means of the creation of a Digital Market where PAs can select the...
Nowadays, more and more Cloud providers are appearing on the market. In this context, a typical issue is represented by the management of distributed services deployed on different federated Cloud providers. Assuming that a distributed service consists of several microservices, in this paper, we specifically focus on the setup of virtual environments and on deployment tasks required in each Federated...
Cloud Federation offers Cloud Service Providers (CSPs) the ability to lease excess capacity to other CSPs in need of temporary additional resources such as large amounts of computational and networking power, or storage capacity to meet consumer's insatiable demand requirements. This promise, not only directly contradicts the Cloud Computing principles of scalability and elasticity, but also challenges...
This paper details the state of the art, the design, development and deployment of the EGI Federated Cloud platform, an e-infrastructure offering scalable and flexible models of utilization to the European research community. While continuing support for the traditional High Throughput Computing model, the EGI Cloud Platform extends its reach to other models of utilization such as long-lived services...
This paper reports on the results of the survey regarding the Research and Education (R&E) clouds in a number of world regions covered by the CHAIN-REDS project, including the sub-Saharan Africa. The survey includes the technical aspects of R&E clouds, as well as issues related to interoperation, interoperability, compatibility, orchestration and federation. Results obtained show a high interest...
Despite the exponential growth in available services and their broad adoption, cloud computing solutions are still heavily affected by the lack of a shared and worldwide accepted standard for their description and exposition to customers. This is reflected in the portability and interoperability issues often arising when customers try to exploit multicloud solutions. In this article the solutions...
Nowadays one of the issues hindering the potential of federating cloud-based infrastructures to reach much larger scales is their standard management and monitoring. In particular, this is true in cases where these federated infrastructures provide emerging Future Internet and Smart Cities-oriented services, such as the Internet of Things (IoT), that benefit from cloud services. The contribution of...
Cloud Computing technologies are gaining increased attention both in academia and practice. Despite of its relevance and potential for more IT flexibility and its beneficial effects on costs, legal uncertainties regarding the data processing especially between large economies still exist on the customer and provider side. Against this background, this contribution aims at providing an overview of...
