24 Ⅲ. SOA Pilot Project Service Discovery Methods (1/2) Business Requirements Business Architecture Organization and Governance Business Process Architecture 비즈니스요구사항이필요한서비스를도출할때까지반복적으로분해 (decomposed) 하는방법 기존시스템을거의사용하지않는새로운응용프로그램개발프로젝트 (green field project) 나기업전반에 SOA를적용하는기획 (enterprise-wide planning) 단계에적절함 이방법만사용할경우실제적용에있어서비스의크기 (Service Granularity) 문제에직면할수있음 Define App domain Model biz process Service = Process Activity Inter-Domain Service Service Identification Framework Service Identification Service Definition Service Implementation Technical Requirements Technical Architecture Information & Application Architecture Infrastructure 기존에존재하고있는서비스나시스템을평가하여기존서비스로등록기존서비스를조합하여새로운서비스를만들수있는가를분석 Business Service catalog가완성될때까지반복 Bottom-up 분석은다른기법에더해거의항상유용하게쓰일수있는방법으로, 존재하고있는서비스에대한 Catalog 를만듦으로써갭 - 분석 (gap analysis) 이가능. Define Model Design CRUD Service = Assembly of CRUD Intra-Application Service Business Event Driven 특정비즈니스이벤트 ( 예 : 계좌소멸, 대출신청등 ) 의생명주기전반에걸쳐필요한개별이벤트를나열하고해당이벤트를처리하는있어서어떠한서비스가필요한지를발굴한다. 이과정을모든핵심비즈니스이벤트에대해서반복한다. Business Event Driven 분석방법은기업이만들어놓은서비스포트폴리오가충분한지를검증하는데도움이됨 24
25 Ⅲ. SOA Pilot Project Service Discovery Methods (2/2) SOA 에서의가장핵심은 Service 를어떻게발견하고 Service 의크기 (Granularity) 를나누는것에달려있습니다. Project Type/Scope Top Down Bottom Up Business Event Driven Decompose The Enterprise Business Model Green Field - - Enterprise Wide Identify Business Domains Top-down Re-Use Existing - Increase Re- Use For Each Domain Identify Services Departmental Project - : High, : Moderate, : Low, - : None Enrich/Refine The Portfolio Using A bottom-up approach Bottom-up Projects Implement Services Refine Portfolio Event-Driven 25

28 Ⅲ. SOA Pilot Project 서비스의 Top-Down 식별 Top-Down 으로비즈니스서비스후보를도출하기위해프로젝트범위에해당하는주요 Business Processes 와 Business Entities 를식별하여후보 Service 들을도출합니다. Business Processes Business Entities 1. 품번을조회하여선택함 2. 업체를조회하여선택함 3. 청구를위한추가정보를입력함 4. 예산을체크함 ( 예산초과시 7번실행 ) 5. 청구를합의함 ( 합의실패시 7번실행 ) 6. 청구를승인함 ( 승인실패시 7번실행 ) 7. 청구거부사유를작성하여담당자에게전달함 8. 승인된청구건을발주시스템에전달하여발주요청 (PR) 을생성함 9. 발주요청건을조회함 ( 실패시 13번실행 ) 10. 발주건이종가가아닌경우견적서작성함 11. 견적서를승인함 ( 실패시 12번실행 ) 12. 발주거부사유를작성하여담당자에게전달함 13. 발주가능후보업체를선정함 (Off line) 14. 품의서를작성함 15. 품의서를승인함 ( 실패시 16번실행 ) 16. 품의거부사유를작성하여담당자에게전달함 17. 발주 (PO) 를생성함 18. 청구생성시스템들에게발주정보를전달함 19. 발주정보를공급업체에게전달함 20. 입고정보 (GR) 를입력함 21. 필요시스템들에게입고정보를전달함 22. 회계전표를처리함 품번 업체 청구 예산 발주 견적 품의 입고 전표 결재 서비스분석및설계 Guiding Principles 서비스설계시가장중요하게적용해야할원칙은 서비스의로직구현 이아니라 서비스의인터페이스 에의해서비스를설계해야한다는것임. 즉 SLA ( 혹은그에준하는서비스제공약속 ) 에의거해서 어떤서비스를제공해야하는지 (Interface) 를설계한후에 어떻게서비스를구현해야하는지 (Implementation) 를설계해야함. 잘알려진 SOA 설계베스트프랙티스중 WSDL 먼저 라는프랙티스는상기한원칙을잘설명해주고있음. 전체서비스인터페이스를식별하는것은어떤비즈니스엔터티와어떤비즈니스프로세스를통해전체비즈니스가동작하는지를분석하는것으로부터출발함. 28

42 Ⅴ. Service Enabling & Hot-Pluggable Verification 5. Service Enabling & Hot-Pluggable Validation 1. SAP 및 Legacy Interface 에 SOA 를적용? 2. 기존자산 ( 웹메소드 ) 를 ESB 로사용!? 3. G/W 결재와 SAP workflow 를 SOA 방식으로연동 Step 6 The Next Step is Step 5 Service Enabling & Hot-Pluggable Verification (SAP, webmethods, Groupware, Etc.) Step 4 Enterprise Domain Decomposition (Procurement & Quality Process) Step 3 SOA Pilot Project(Procurement Process & SAP interface) Step 2 ORACLE SOA Best Practice Analysis Step 1 ORACLE SOA Solution Overview (SOA Technical Enabler) 42
43 Ⅴ. Service Enabling & Hot-Pluggable Verification 5.1 SAP Services Enabling (1/2) SAP 과 Legacy 간의예상되는인터페이스분석을통한서비스도출 기존방식 웹서비스방식 Batch : 9 종 Online : 53 종 인터페이스표준화재사용고려 Batch 제외 서비스 : 23 종 ( 판매금융 41 종 11 종 ) 예상되는인터페이스분석을통한서비스도출 SAP Services Enabling Method 43
44 Ⅴ. Service Enabling & Hot-Pluggable Verification 5.1 SAP Services Enabling (2/2) Web Services를조합하여비즈니스서비스구현판매금융에서도출된웹서비스를조합하여비즈니스서비스를발굴하였습니다. 이러한비즈니스서비스발굴을통해단순인터페이스방식의변경에서비즈니스와IT가결합되어SOA의효과가극대화될수있다는장점이생기게됩니다. 개별서비스호출사례 Composite 서비스호출사례 국내판매 (SAP SD) ABAP 서비스프락시 SOAP over HTTP 서비스인터페이스 판매금융예약정보계정잔액전표 국내판매 (SAP SD) ABAP SOAP over HTTP 계약금입금처리서비스 판매금융예약정보계정잔액전표 할부관리카드 할부관리카드 Composite Service 사용의장점 개발편의성 서비스재사용성 관리편의성 Enterprise Services 44
45 Ⅴ. Service Enabling & Hot-Pluggable Verification 5.2 결재서비스 Enabling (1/2) Groupware Approval Service & SAP Workflow Enabling 결재엔진은.Net 기반의 In-House 시스템을활용하고 SAP는 SAP Workflow를통하여이벤트를 BPEL에전달하였습니다. 시스템간인터페이스방식은모두웹서비스로구현되었으며, 웹서비스를사용하여전체프로세스를진행하는데문제없음을검증하였습니다. Groupware 결재엔진 결재상신 결재완료 ESB ( 웹메소드 ) 결재상신서비스 결재결과라우팅서비스 BPEL PO 정보 입고정보 전표정보결재의뢰결재결과전표확정 PO 생성 입고 전표생성 전표확정 45
46 Ⅴ. Service Enabling & Hot-Pluggable Verification 5.2 결재서비스 Enabling (2/2) ORACLE BPEL PM을이용한결재서비스구현결재서비스자체는 Groupware에서제공될수도있고 ORACLE BPEL Process Manager에서제공하는 Human Workflow를사용하여구현될수도있습니다. Human Workflow는 SOA 기반의 BPM을 ORACLE BPEL PM을통해구현한대부분의업체에서사용하고있으며포스코의경우, 업무결재자체를 ORACLE BPEL PM으로구현하였습니다. 6 필요한경우 SAP GUI 화면호출 5 Detail 화면에서내역을확인하고작업처리 ( 승인 / 반려 / 전달등 ) 4 사용자는포탈에로그인하여자신에게할당된 Task 를확인 SAP GUI Task Detail 화면 Work List 화면 PP QM SD MM PM R/3 Client / Server ABAP/4 HR FI CO WF IS 1 SAP 에서발생한결재정보가 Interface Layer 를통해 BPEL Process 기동 AM PS 결재내용 Integration Layer 결재결과 9 SAP에결과반영 2 디자인된 Flow 에따라작업처리및 Workflow 서비스호출 BPEL Process Assign Tasks Task Complete 8 처리결과에따라다음 Activity (SAP 서비스호출등 ) 진행. 7 처리결과전달 웹서비스 Human Workflow Service 3 정해진사용자 / 롤 / 그룹에 Task 생성 46
47 Ⅴ. Service Enabling & Hot-Pluggable Verification 5.3 Hot-Pluggable Test (ESB 연동테스트 ) (1/2) SOA Solution Stack & webmethods 연동테스트 SOA Solution Architecture의특징은기존 WebMethods로적용된 Integration back-bone을 ESB로활용하는데있습니다. 다음과같은 webmethods와 ORACLE SOA Solution과의연동 Test를진행하여상호호환성을검증할필요가있습니다. Business User Interface Hot Pluggable 검증절차 A 社 BPA (ARIS) IDE (JDeveloper) Business Activity Monitoring Process 4 Business Rules Portal & Collaboration Human Workflow ORACLE BPEL Process Manager 1 Alerts/ Notifications System Monitoring 1. 기존개발된웹메소드 ESB 상의인터페이스를웹서비스로노출 2. 노출된 WSDL 을 ORACLE Registry 에등록 3.BPEL 상에서 Registry 검색및 Binding SOA 4.BPEL 적용Process 전 BPM 를웹서비스구축이로노출미지 (WSDL 생성 ) Service Registry 2 Integration ORACLE Backbone Enterprise (WebMethods) Service Bus as ESB 3 Security (OWSM) 5. 노출된 BPEL WSDL 을 ORACLE Registry 에등록 6. 웹메소드에서 Registry 검색및 Binding Adapters B2B Java.NET W.S MDM 7. 웹서비스의 OWSM 등록및관리 47
48 Ⅴ. Service Enabling & Hot-Pluggable Verification 5.3 Hot-Pluggable Test (ESB 연동테스트 ) (2/2) ORACLE Hot-Pluggable 정책 ORACLE은글로벌 S/W 메이저벤더 (ORACLE, IBM, BEA, Microsoft, SAP) 중유일하게 Hot-pluggable 정책을적용하는벤더입니다. Hot-Pluggable 정책이란자사의제품이타사의제품과호환성을보장함은물론타사제품위에서도동작하게끔제품의호환성및표준을준수하는정책으로고객은자사 IT 환경에제품을유연하게적용할수있으며기존 IT 투자를보호할수있습니다. Apps SAP R/3, mysap, all ORACLE Applications WSRP and JSR-168 Portals, MS Office, Wireless and Mobile Devices Eclipse, CollabNet Subversion, Spring, Struts, JUnit, Ant, Tapestry, CVS, MS Visual SourceSafe Teradata, DB2, MS Analysis Services, SAP BW, Cognos, Business Objects IBM WebSphereMQ, TIBCO Enterprise for JMS, SonicMQ BEA WebLogic, IBM WebSphere, JBoss App Server, Apache Tomcat Certify on all major Operating Systems HP OpenView, CA Unicenter, IBM Tivoli, BMC Patrol MS Active Directory & MIIS, CA etrust SSO, all LDAP Directories DBs IBM DB2 & Informix, MS SQL Server, Sybase IQ 48
49 Ⅵ. The Next Step is 6. Next Step Next Step is? Step 6 The Next Step is Step 5 Service Enabling & Hot-Pluggable Verification (SAP, webmethods, Groupware, MDM) Step 4 SOA Business Pilot(Procurement & Quality Process) Step 3 SOA Pilot Project(Procurement Process & SAP interface) Step 2 ORACLE SOA Best Practice Analysis Step 1 ORACLE SOA Solution Overview (SOA Technical Enabler) 49
50 Ⅵ. The Next Step is 6.1 The Next Step is SOA 성숙도향상 SOA Governance 체계수립 SOA Governance 적용범위및내용 SOA Governance 적용절차 SOA 적용 / 설계 / 개발표준수립 50
51 Conclusion Conclusion - Goldman Sachs No.1 SOA Partner Goldman Sachs, IT Spending Survey, Laura Conigliaro, Rick Sherlund, Sarah Friar, Derek Bingham, December, 2006 골드만삭스의조사에의하면 ORACLE 을 SOA 의전략적파트너로꼽는기업이매해증가하여 2006 년말에는 IBM, BEA, Microsoft 를제치고최고의응답을받았습니다. 51
