SOA(Service Oriented Architecture)의 정의

서비스지향 아키텍처는상호 작동 하는 시스템 사이를

느슨하게 연결하려는 목적을 가진 아키텍처다.

서비스란서비스 소비자가 원하는 결과를 얻기 위해

서비스 제공자가 처리해 주는한가지 일의 단위를 말한다

Dr. Hao He, W3C Web Services Architecture Working Group

SOA의 특징

서비스는느슨하게연결되어있다.서비스는자기설명적인인터페이스를가진다.메시지는정형적으로정의된다

서비스는드러나져있다.서비스는상호운용성이있다.서비스는플렛폼-독립적으로설계되어야한다. 서비스는재사용가능하다.

SOA의 이점잘정의된인터페이스

– 구현변경시클라이언트에영향이없다

생산성과재사용성의향상– 기존비즈니스서비스의토대위에새로운기능구축

유지보수와구현이동의쉬움– 변경, 버전관리는전부가아닌필요부분만비즈니스유연성과민첩성의향상

– 코드수정대신에프로세스모델의변경만으로새로운비즈니스프로세스에대응가능하다

SOA와웹서비스SOA는소프트웨어설계원리

웹서비스는일종의기술명세(Technology Spec.)

“근래에각광받는웹서비스는 SOA를 중요한개념이되게하였고, SOA의모범적아키텍처는성공적으로웹서비스를시작할수있게할것이다.”

“2008년까지, 새로운 SOA 또는 웹서비스프로젝트의75%는 SOA와웹서비스가동시에구현될것이다.”

“지금까지, IBM, Microsoft 그리고 BEA는새로운 BPEL 표준의가장활동적인주요지원업체였었다. 이제오라클은최초로구체적인 BPEL제품을출시함으로써그들을앞질렀다.”

- David Smith, Research Vice President and Fellow, Gartner
