Bootstrapping provisioning engines for on-demand provisioning in cloud environments

The assumption that services should run continuously is no longer reasonable in science oriented environments, where dynamic working approaches lead to fluctuating service utilization. Making services available on-demand would be better suited in those situations. For on-demand provisioning of services in cloud environments, suitable provisioning engines have to be set up first. This diploma thesis presents the design for a 2-tiered bootware component that deploys provisioning engines into remote environments that can then be used to provision services on-demand. The bootware can be called by other components via a web service interface and supports multiple provisioning engines and cloud environment via plugins. The integration of the bootware into the SimTech SWfMS with an Eclipse plugin is also described, the bootware however is designed to be generic and can be used together with other systems

Applying a Web-Service-Based Model to Dynamic Service-Deployment

Owing to the increase in both heterogeneity and complexity in today’s networking systems, the need arises for an architecture for network-based services that provides flexibility and efficiency in the definition, deployment and execution of the services and, at the same time, takes care of the adaptability and evolution of such services. In this paper we present an approach that applies a component model to GT4, a Webservice-based Grid environment, that enables the provision of parallel applications as QoS-aware (Grid) services, whose performance characteristics may be dynamically negotiated between a client application and service providers. Our component model allows context dependencies to be explicitly expressed and dynamically managed with respect to the hosting environment, computational resources, and dependencies on other components. Our work can be seen as a first step towards a component-based programming model for service-oriented infrastructures utilizing standard Web-service technologies. 1
