AOT LAB Service Oriented Architecture HTTP Web Application RMI Java Application. NET REMOTING . NET Application Features CORBA Legacy SW ODBC Logical view SOA Data Base ERP, CRM w There is no one recognized definition of SOA w § A service is an abstracted, logical view of actual programs, databases, business processes Message orientation JCA Definition w A baseline of concepts and principles and a strategic vision have emerged SOA is an architectural style that supports service orientation Service orientation is a way of thinking in terms of services and service-based development. § 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) 2

AOT LAB SOA vs. JBI/ESB w 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 15
AOT LAB SOA vs. JBI/ESB w 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. Using JBI for Service-Oriented Integration (SOI) Ron Ten-Hove, Sun Microsystems January 27, 2006 w The ESB as a Pattern for SOA The Role of the Enterprise Service Bus W.
