3 SCA SCA = Service Component Architecture Mix between Service and Component paradigms Main advantages (... PHP Several implementation languages (Java, C++, Cobol, (... JMS Several communication protocols (WS, RMI, Seen like a powerful way to turn existing code into services Specification defined by OSOA Consortium Supported by IBM, BEA, IONA, Oracle, SAP... Standardization by OASIS in progress First version expected in June

9 SCA vs. JBI Many questions about their relation Both focus on Service Oriented Architecture JBI is used to implement integration platforms The only standard to focus on loosely coupling Binding components to communicate with external world Service engines to propose technical features Orchestration, transformation... Used to integrate applications in an SOA SCA can be used to build service composite in a JBI environment Using the JBI bindings 9

10 Benefits of an ESB (JBI) with SCA Service Adaptation (ESB provide message mapping/enrichment, ( protocol Service Orchestration (composite services can be used to address new ( needs business SCA references are not hardwired in the SCA application 10

12 FraSCAti as a Service Engine ( 1 ) Extend FraSCAti to support the JBI binding Add a JBI plugin to FraSCAti pluggable architecture Integrate Frascati as a service engine Expose new services in PEtALS via composite services Consume existing services in PEtALS via composite references Delegate remote binding of the SCA composite to PEtALS The composite is running in FraSCAti service engine Remote calls handled by the PEtALS binding components 12
