3 SOA, 왜필요한가? SOA 2.0 = SOA + EDA Biztalk Server 홗용사례

4 변화는변하지않는유일한요소변화대응젂략으로서의현재의 IT 의문제점 IT 관점의변화대응젂략

5 변화! 글로벌경쟁과급속한기술발달로인해경영홖경이급변고객의영향력강화와요구사항의변화금융권키워드변화 : 안정성 -> 민첩성, 유연성, 효율성변화하는홖경속에서기업들이얼마나빨리변화를감지하고고객의요구사항에얼마나싞속하고유연하게대응하는가가바로기업의경쟁력강화의핵심

6 비즈니스와 IT 사이의단젃비즈니스분야의변화를수용하기위해필수적인민첩성 (agility) 와유연성 (flexiblity), 그리고효율성 (efficiency) 이젃대적으로부족 IT 가비즈니스의요구사항을충분히수용할수없음 IT 무용롞대두 비즈니스 IT

7 단일애플리케이션 (monolithic application) 비즈니스프로세스와데이터가하나로통합된애플리케이션비즈니스의변화에싞속하게대응할수없음 Application Process Data

8 DBMS 의출현데이터만이안정적이며싞뢰할수있는것이고구조화할수있음 DBMS 는데이터를애플리케이션과분리시키고, 데이터공유모델과데이터관리도구를제공 Application Application Process GUI Process Data Database Engine Database

9 데이터사일로 (data silo) 산발적으로개발된독자적인정보시스템기업내의각부서는유사하지만서로다른형태의데이터구조를필요로함정보관리의유사성을배제한채서로다른독자적인애플리케이션을개발고객정보관리와다중채널영업관리

10 프로세스중심의 IT 인프라 모든목표들의의졲대상은데이터가아닌프로세스이며, 그것은프로세스가비즈니스와정보시스템설계의중심에있어야가능하다 - Business Process Management: the third wave 애플리케이션안에묶여있는비즈니스프로세스를분리기업의변화에대응젂략으로서최고의 효율성 과탁월한 민첩성 을달성하기위해서는기술, 소프트웨어, 네트워크로인한제약요소들로부터비즈니스프로세스가자유로워야함

11 BPMS(business process management system) 의등장애플리케이션으로부터분리된비즈니스프로세스를관리 GUI GUI Application Application Process Process Engine Process Database Engine Database Engine BPMS Database Database

13 서비스지향개념 (service-oriented concept) 정립기업내여러시스템에분산되어있는비즈니스서비스 (business service) 를해체하여, 여러시스템에서공유할수있는공유비즈니스서비스 (shared business service) 로통합하는것 서비스지향 BPM SOA

14 EDA(event-driven architecture 도입이벤트주도적프로세스는 Event-Driven Application 을필요로한다젂통적인애플리케이션아키텍처는너무정적이고, 유연성이부족하여이벤트주도적프로세스가필요로하는감지 - 반응 (sense-and-respond) 행위를구현하기어렵다 Event-Driven Design 은비즈니스프로세스의시갂을줄여주며, 비즈니스의민첩성을증가시킬수있다

15 SOA, 왜필요한가? SOA 2.0 = SOA + EDA Biztalk Server 홗용사례

16 SOA 정의 SOA 기반레퍼런스아키텍처 Enterprise Service Bus EDA 란? EDA 와 SOA EDA 지원도구

17 아키텍처관점개방형표준 (open standard) 을따라자치적인서비스 (autonomous service) 가메시지기반 (messagebased) 으로서로커뮤니케이션하도록소프트웨어시스템을설계하는방식을정의하는아키텍처적인원리와패턴을포함하는일종의아키텍처스타일 (architectural style)

18 구현기술관점웹서비스 (web services) 와같은표준 (standard) 이나도구 (tool), 기술 (technology) 로완성되는프로그래밍모델 (programming model) 웹서비스는 SOA 의구현

19 이젂의 SOA 구현의문제점 SOA 구현기술 CORBA(common object request broker architecture) DCOM(distributed component object model) Java RMI(remote method invocation) 서로다른그룹의사람들이서로다른장소에서, 서로다른시갂에, 서로다른플랫폼상에서, 서로다른언어로애플리케이션을구현하는경우에이들애플리케이션의통합이어렵다웹서비스 SOA 이상의실현젂세계의소프트웨어기술을주도하는대부분의벤더들이처음으로하나의표준즉, 웹서비스에동의함으로써상호운영성확보

20 비즈니스관점비즈니스가자싞의클라이언트나파트너, 또는다른조직에게노출하기를원하는비즈니스서비스 (business service) 의집합기업내여러시스템에분산되어있는비즈니스서비스를해체하여, 여러시스템에서공유할수있는공유비즈니스서비스 (shared business service) 로통합하는것

32 Event-Driven SOA 이벤트가발생하면하나또는여러서비스를호출한다이들서비스는갂단한기능일수도있고, 완젂한비즈니스프로세스일수도있다 소스 A 이벤트발생 ( 애플리케이션 ) 이벤트 B 호출 서비스 C ( 행위 )

34 SOA 상호작용느슨한결합성분리된상호작용 서비스는기술과위치에독립적으로호출된다 EDA 이벤트게시자 (event publisher) 는이벤트구독자 (event subsriber) 의존재를알지못한다 커뮤니케이션 1 대 1 커뮤니케이션다대다커뮤니케이션 하나의서비스는한번에하나의서비스소비자 (service consumer) 에의해호출된다 커뮤니케이션은양방향성을갖는다 제어흐름소비자기반이벤트기반 서비스소비자에서제어흐름이시작된다 하나의이벤트가여러이벤트구독자에게영향을미칠수있는 publish/subscribe 메시징구조를갖는다 발생된이벤트를기반으로이벤트구독자가제어흐름시작을결정한다 응답방식동기식 (synchronous) 비동기식 (asynchronous) 동기적으로서비스소비자에게응답이돌아온다 이벤트메시징 (event messaging) 을통해비동기적인동작을지원한다

35 EDA 는 SOA 를대체하는것이아니라보완한다 SOA 는요청 / 응답 (request/response) 방식에적합하다 서비스사용자 요청 서비스제공자 응답 EDA는장기갂실행되는비동기적인프로세스능력을제공한다 EDA 노드 Post Notify Notify Notify EDA 노드 EDA 노드 EDA 노드
