-The project, promoted by the European Commission, is committed to the ‘hybrid cloud’ with an investment of 10.5 million euros over three years
-The objective is to optimise the life cycle of the services offered by a Cloud, covering everything from the development of the services to their deployment and operation, and to create a full toolkit which will be available to companies and organisations
Abstract: Cloud computing has emerged as the new trend in the IT industry. However, in order for the adopters of this technology to be legally compliant with regard to the handling of personal data, a series of actions must be undertaken. In this paper, we present the legal requirements that exist inside the EU with regard to transnational data transfer and storage. Based on these legal requirements, we then used the WS-Agreement standard to create corresponding SLAs.
Despite the widespread support for live migration of Virtual Machines (VMs) in current hypervisors, these have significant shortcomings when it comes to migration of certain types of VMs. More specifically, with existing algorithms, there is a high risk of service interruption when migrating VMs with high workloads and/or over low-bandwidth networks. In these cases, VM memory pages are dirtied faster than they can be transferred over the network, which leads to extended migration downtime.
Cloud Computing is considered nowadays as the future of ICT systems leveraging new methodologies for developing, providing and consuming services. Even though many people believe that Cloud is just another buzzword for utility computing, this new computing paradigm is not only changing the design of modern computing platforms in technical level, but it also impels, from the market perspective, the creation of new value chains and business models.
A recent survey of the 451group on Cloud usage highlights software licensing as one of the top five obstacles for Cloud computing, quite similar to what has been observed in the Grid already a couple of years. The reasons are the same: the current praxis of software licensing, both in terms of business models and licensing technology.
