Wrapper Based Adaptive Management of Concurrent Workflow Executions

摘要

This work relates to data centre systems, where a provider hosts applications, used in the context of Service Level Agreements (SLA). However, the applications are structured as composite services, i.e. workflows. Thus, the work relates also to service composition. In a possible scenario an organization exports a collection of application services, based on a pool of computational resources and a pool of (possibly redundant, possibly hierarchically composed) component services.
