This comprehensive guide by Franca Perrina & Elaine Isnard of OASIS Team - INRIA introduces ProActive Parallel Web Services for seamless integration into Service-Oriented Architecture (SOA). The book covers essential concepts like Business Services, Job Scheduling, Parallelization Services, and Domain-Specific Services. It emphasizes the flexibility of implementing parallel computing patterns and business functionalities. With a focus on operational and high-level services, it enables users to execute application-specific logic efficiently. The text offers insights into building business services from scratch or via lower-level service composition. Additionally, it highlights the importance of Parallel Services and Grid computing. The authors detail how to implement a variety of services, such as Parameter Sweeping and Divide & Conquer, within the context of business processes. Through the use of ProActive Scheduler and Resource Manager, the book showcases an architecture that enhances the scalability and performance of Web services. Perrina & Isnard's work is a valuable resource for those looking to optimize service logic execution and storage management in a service-oriented approach.

Other Basic Service Other Operational Service Job Scheduling Service High level Business Process Domain specific Service Parameter Sweeping Service Divide & Conquer Service Context • Business services: services providing business functionalities. • (Their implementation can be parallel or not) • Job Scheduling service: service of resource virtualization to run jobs on the Grid. • Parallelization services: provide the implementation of typical parallel computing patterns. • The user has to provide the application specific logic to be executed according to the desired pattern. In a service oriented approach, business services may be built from scratch or can be built composing and reusing lower level services. … … … Operational Services Parallel Services Grid F.
