Our Problem We need our applications to execute business logic in many other systems Java applications executing Natural.NET applications executing Natural Natural executing Java or.NET Java executing.NET

We need SOA! “Service” Oriented Architecture is a strategy in which applications rely on services. What is a Service? Well defined & Standardized interface Coarse grain, performing a related set of business functions, as opposed to a single function Self-contained without dependencies to other services “loosely coupled” so they can be reused in contexts not known at design time Service consumer & Service provider Request / Response Event Driven
