In scientific data analysis, workflows are used to integrate and coordinate resources such as databases and tools. Workflows are normally executed by an orchestrator that invokes component services and mediates data transport between them. Scientific data are frequently large, and brokering large data increases the load on the orchestrator and reduces workflow performance. To remedy this problem, we demonstrate how plain SOAP web services can be tailored to support direct service-to-service data transport, thus allowing the orchestrator to delegate the data-flow. We formally define a data-flow delegation message, develop an XML schema for it, and analyze performance improvement of data-flow delegation empirically in comparison with the regular orchestration using an example bioinformatics workflow.

“…Advanced dependency management is not required because each service only has a single dependency, namely the previous service, and process fragmentation is straight forward. Approaches to distributed coordination among service providers are based on direct interaction [10], [11] or use shared tuplespaces [12], [13]. The advantage of shared tuplespaces is that communicating parties do not have to be present at the same time, as they anonymously exchange data and control via a piece of shared memory.…”

“…However, shared tuplespaces consume high resources and suffer from efficiency and scalability issues due to global synchronisation requirements [14]. Continuation passing [10] and migration of process descriptions [11] use direct interaction and are similar to our approach of transferring control among service providers. Continuation passing allocates control hop-by-hop and activates subsequent service providers by passing the remainder of the execution along with asynchronous messages.…”

“…As in other approaches [8], [10], the peers in our model operate on only a part of the request and send the remainder to the next peer. This partial request processing involves two major tasks: binding a service provider address to a required sub-service and executing a sub-service based on the output of the previous sub-services.…”

Abstract-Dynamic service composition has emerged as a promising approach to build complex runtime-adaptable applications as it allows for binding service providers only shortly before service execution. However, the dynamic and ad hoc nature of mobile computing environments poses a significant challenge for dynamic service composition. In particular, the lack of central control and the potential volatility of service providers increase the complexity and failure probability of the composition process. Although, current research has led to decentralised composition algorithms and failure recovery strategies, the key question of how to reduce the failure probability of a composition still remains. We address this question and propose opportunistic service composition, an optimised execution model for complex service requests. The model merges the execution phase into the dynamic binding phase and supports the immediate fulfilment of partially composed service requests. We evaluated our model in mobile ad hoc network simulations. The results show an improvement over a baseline approach regarding composition success, response time, and communication effort.

“…In contrast to the above mentioned centralized approaches, Yu et al [8] adopted a decentralized choreogra- phy messaging style for executing a BPEL workflow. In this setup, the message that is passed to a component service instructs it to carry out the immediate activity of the workflow, and to subsequently continue the remaining activities of the workflow by invoking the next service.…”

Scientific workflow systems facilitate scientific experiments by integrating and coordinating geographically distributed data and algorithmic services in a loosely coupled manner. Most scientific workflow-engines use centralized coordination as the choice of approach for executing workflows, requiring the coordinator (i.e., workflow-engine) to send and receive all input and output data of component services. Such indirect data communication between the component services increases the data-traffic of the coordinator and weakens the performance of the workflow. To optimize this, we propose an approach where data-flow is dynamically delegated from the coordinator to the component services, with direct transportation of data between the component services.
