Introduction - SOA• Service-oriented architecture (SOA)

– an architectural style for developing systems and applications

– well-defined logical entities (services), which can be independently used

• Web Service Architecture– Realization of the SOA model– Web Service transport (HTTP)– Web Service messaging (SOAP)– Web Service description (WSDL)– Web Service discovery (UDDI)– Web Service composition (BPEL) 2/20

Introduction - BPM• Business process management (BPM)

platforms provide methods, techniques, and software for design, enact, control, and analyze of business processes

SOA-based BPM platforms

• SOA-based BPM platforms provide capabilities for business process modeling, execution, monitoring and optimization through the support of the Web services standards

• Features of the platforms are process flexibility, easy integration and reuse of assets.

4/20

SOA-based BPM Characteristics

• Web Service description (WSDL)

• BPEL for Web Service composition

• Registries for Web Service reuse and discovery

• Adapters for access to outer systems

• Enterprise service bus (ESB) – mediator between Web Services

and business processes, infrastructure for message exchange

• Human tasks (HT)

• Business rules management (BR)

• Business process monitoring (BM)

5/20

Motivation• The European Grid Infrastructure (EGI) uses

partially service-oriented grid middleware for grid computing (g-Lite)– No service registry or service registry support;– No discovery service;– No service composition;– No well-defined web service description;

• In this context a SOA-based BPM platforms for the EGI will improve the development of flexible service-oriented solutions and will provide a framework for business process management in the grid infrastructure.

The goal of the research

• To propose architecture of a SOA-based platform which to support the management of business processes in the EGI

• To describe approach for business process definition, design and execution in the EGI, based on proposed architecture

Supplementary requirements

The EGI is not service-oriented: Not all EGI

services are service-oriented

The EGI does not provide service for

composition: g-Lite does not provide

mechanism for EGI services composition into

business processes

The EGI can not be extended with ESB: g-Lite

structure currently can not be extended with the

enterprise service bus
