Introducing SOA An Approach For Building Agile and Flexible Business Applications Loosely coupled systems = loosely coupled (flexible) business processes SOA Is Not: A product or application A specific technology A specific standard A specific set of rules SOA-1: Fundamentals of Service-Oriented Architecture

Service Implementation Service Provider It’s all about Services… Accomplishes A Defined, Self-Contained Unit Of Work Does not depend on the state of other process/functions Internal Details Hidden Programming language The execution logic The data store (if any) Exposes An Agreed-Upon Interface Stable- built to last! Service Interface Service Implementation Data Service Logic SOA-1: Fundamentals of Service-Oriented Architecture

Service Contract What Service Operations Are Available Terms And Conditions For Service Requestor What Service Operations Are Available The input & output messages supported by each operation The data representation model of each message's contents Rules/Policies For Using The Service Quality Of Service Aspects SOA-1: Fundamentals of Service-Oriented Architecture

Implementing Service Contracts Some possibilities… Hardcopy Specification Shared XML Schema Representational State Transfer (REST) HTTP Get/Post/Put/Delete and XML Web Service Description Language (WSDL) Available business methods (“operations”) Message structure (data fields, types) Bindings for operations (SOAP over HTTP) SOA-1: Fundamentals of Service-Oriented Architecture
