Service Clouds are a key emerging feature of the Future Internet which will provide a platform to execute virtualized services. To effectively operate a service cloud there needs to be a monitoring system which provides data on the actual usage and changes in resources of the cloud and of the services running in the cloud. We present the main aspects of(More)
Cloud computing [23] is a promising paradigm for the provisioning of IT services. Cloud computing infrastructures, such as those offered by the RESERVOIR project, aim to facilitate the deployment, management and execution of services across multiple physical locations in a seamless manner. In order for service providers to meet their quality of service(More)
The grid community has been migrating towards service-oriented architectures as a means of exposing and interacting with computational resources across organizational boundaries. The adoption of Web Service standards provides us with an increased level of manageability, extensibility and interoperability between loosely coupled services that is crucial to(More)
In order for existing grid middleware to remain viable it is important to investigate their potential for integration with emerging grid standards and architectural schemes. The Open Grid Services Architecture (OGSA), developed by the Globus Alliance and based on standard XML-based web services technology, was the first attempt to identify the architectural(More)
— The integration of clusters of computers into computational grids has recently gained the attention of many computational scientists. While considerable progress has been made in building middleware and workflow tools that facilitate the sharing of compute resources, little attention has been paid to grid scheduling and load balancing techniques to reduce(More)
The Java-UML Lightweight Enumerator (JULE) tool implements a vitally important aspect of the framework for software tool certification - test suite generation. The framework uses UML models as the test inputs for the bounded exhaustive-testing approach. Within a size bound for the metamodel types, JULE enumerates only the set of non-isomorphic models in the(More)
Grid computing has the potential to revolutionise how small groups of simulation scientists work together to tackle new science problems. In this paper we report how the eMinerals project has developed a small scale integrated compute and data grid infrastructure – the eMinerals minigrid – and developed generic job submission tools that exploit this(More)
