The current trend towards dynamic and highly scalable service provisioning fosters the rise of Software as a Service (SaaS) platforms and so called Compute Clouds. The on-demand provisioning of services gains more and more influence. For offering enriched services that are capable of performing complex tasks, the dynamic composition of such services becomes important. In order to enable the collaboration...
The authors provide a criteria catalogue to characterize cloud computing and their own Cloud Business Ontology Model to classify current product offerings and pricing models.
Until recently, only few grid and cluster systems provided preemptive migration (e.g. [4]), which is the ability of dynamically moving computational tasks across machines during runtime. The emergent technology of virtualization (e.g. [10]) provides off-the-shelf support for migration, thus making the use of this feature widely accessible. Existing literature largely neglects the close interrelationship...
Applying economic principles to grids is deemed promising to improve the overall value provided by such systems. End users can influence the allocation of resources by reporting valuations for these resources. Current market-based schedulers, however, are static, assume the availability of complete information about jobs (in particular with respect to processing times), and do not make use of the...
Grid technology denotes a computing paradigm in which computing resources are shared across geographical and administrative boundaries. Market-based mechanisms are deemed promising to provide a better fit to grids' strategic and dynamic nature than classic technical schedulers. In this paper, we present a deterministic heuristic that achieves the distinct trade-off between scalability by approximation...
Grid computing is a promising concept to increase the efficiency of existing computing systems and to cut down on IT expenses by allowing the dynamic access to computer resources across geographical and organizational boundaries. These inter-organizational settings require a scheduling strategy for flexibly and efficiently matching resource requests to idle resources. Market-based mechanisms promise...
