2 AOT LAB LAB Service Oriented Architecture Features A baseline of concepts and principles and a strategic vision have emerged Logical view  A service is an abstracted, logical view of actual programs, databases, business processes Message orientation  A service is defined in terms of the messages exchanged between the parts Description orientation  A service is described by machine-processable meta data Granularity  Services tend to use a small number of operations with relatively large and complex messages Platform neutral  Messages are sent in a platform-neutral, standardized format (XML) Legacy SW Data Base ERP, CRM Web Application Java Application.NET Application HTTP RMI.NET REMOTING CORBA ODBC JCA SOA Definition  There is no one recognized definition of SOA  SOA is an architectural style that supports service orientation  Service orientation is a way of thinking in terms of services and service-based development.

3 AOT LAB LAB Service Oriented Architecture Legacy SW Data Base ERP, CRM Web Application Java Application.NET Application HTTP RMI.NET REMOTING CORBA ODBC JCA SOA Problems  Rely on static syntactical description of service interfaces  They guarantee services binding at design time  Do not address service selection based on a dynamic assessment of nonfunctional attributes  They guarantee syntactic interoperability, but they fail to provide semantic operability Open issues  How to efficiently discover Web services  Semantic annotations  Federations and peer-to-peer discovery  How to allow and facilitate their composition  Semantic annotations  Workflow technologies  AI techniques

15 AOT LAB LAB SOA vs. JBI/ESB  SOA and ESB Are More Than Different Answers to the Same Problem  ESB is designed assuming a world of horizontal layers - such as database, application logic, … SOA is designed for a world of vertical slices through the IT infrastructure - such as ordering, fulfillment, billing, etc. Computerworld 2005

16 AOT LAB LAB SOA vs. JBI/ESB  JBI is a Java standard for structuring business integration systems along SOA lines. It defines an environment for plug-in components that interact using a services model based directly on WSDL 2.0.
