SOA Benefits for GM• Support Business Agility

– Speed: Faster deployment of new business direction • Assemble and reassemble applications from

reusable services• Rapid integration with joint ventures, suppliers,

dealers, branches, …– Flexibility: Significantly expand the available pool of

trading partners• Commonize Continually Improving Business Execution

– Act as One Company: Shared services and business behavior – Use the latest services as they are created (flexible extension)

• Reduced Business Interruptions– Loose coupling improves availability and recovery for global

distributed systems – Core set of thoroughly tested, highly-available services

SOA Benefits for GM• IT Cost Savings

– Accomplish more with development budget• Services reuse is aimed at GM’s outsourced model

• Business process modelers can assemble portions of application

• Faster development of new applications

• Recycle/migrate legacy applications as new services– Reduction in sustaining costs

• Convert and merge legacy functionality into Web Services

• Reduction in deployment environment diversity• Market-centric solution

– Component and SOA are the dominant complementary architectures:

• J2EE™ + WebServices + ebXML– Increased competition among product vendors and

software development vendors

Session 1543

• Purpose: Define GM’s Application Architecture and IT Standards for SOA; Evangelize

• Deliverables: Reusable Architectural Patterns and RI for WebServices and ebXML; Recommendations

• Approach: Enterprise-level IT provides SOA technology and methodology leadership

• Funding: Application Solutions Delivery corporate budget• Key contributors: BEA, IBM, New Era of Networks and Sun• GM’s development model:

– Mostly outsourced to Software Factories– Buy before build; committed to open standards– Legacy is dominant; most new development is

for the J2EE™ platform

ebXML Applications at GM• GM Approved XML Standards (Q1 2002)

– OAG BODs: XML Business Document Standard– ebXML: B2B XML Technical Standard

• Application categories: – Dealers: Inventory mgmt., financial data, parts – OnStar: Vehicle on-board services– Supply Chain: Purchasing and OTD– Engineering Suppliers: Global concurrent engineering– Finance: Loan/lease collaboration with branches

• Kicked off GM-Covisint B2B XML integration pilot using ebXML MSH (Q2 2002); Target completion in Q3 2002

ebXML Architecture @ GM

Session 1543 1

GM RI Architectural Features● Reference Architecture based on:

– J2EE—Component Model – Basic Web Services (SOAP, WSDL, UDDI)—Services Layer– ebXML—Expose SOA to trading partners

● Key Aspect—Multi-Tiered Choreography Engines

– Loosely coupled web services applications in back end– Business process collaborations between trading

partners

● Allows for Declarative Development—XML document defines

– New web services applications– New Trading Partner Agreements– New Business Process Collaborations

Session 1543 1

ebXML Architecture Modules ● MSH—Message Service Handler provides reliable

message delivery● CPP/CPA—TP Service Discovery and Agreements

defines protocols, security, timeouts, between trading partners

● BPSS Collaboration—Business Process Specification Schema for managing collaboration between trading partners

● CC XML Grammers—Core Components/Business Object Diagrams Industry standard (OAGIS/STAR) XML grammars

● ebXML Registry and Repository—B2B Document Management System

● Complete B2B web services framework—A complete specification with available implementations to extend an SOA to trading partners

When to Consider ebXML• B2B or large A2A Environments—Extending or integrating

enterprise SOAs, or when loosely coupled messaging is desirable• Need Reliable Messaging—When enterprise services perform

updates, insert, or deletes to the underlying data model, reliable messaging becomes critical

• Security is a Concern—When different security profiles and requirements exist between trading partners

• High scalability requirements—ebXML’s loosely coupled messaging architecture allows for horizontal scalability, queueing, and clustering

• Want to Leverage Industry Standards—XML grammars, business process modeling and trading partner agreements

Next Steps for SOA at GM

• Path forward for GM:– 4Q2002:

• Enhance the RI:– Throughput and performance benchmarks for

WS and ebXML– Incorporate BODs into RI

• Standardize products and process for SOA:– Guidelines for integration (data vs. behavior)– Formalize the use of UDDI and Registry– Mentor WS and ebXML pilot projects– GM standards for choreography and collaboration

management– Funding model accepted across IT divisions

Session 1543

Next Steps for SOA at GM

• Path forward for GM (Cont.):– During 2003:

• Standards incorporated:– Select standards for ‘Business Transaction Management’ for

ebXML and ‘XA’ for WS (WS-Transactions and OASIS BTP)– Incorporate seamless security (WS-Security and ebXML Security)– Expedite delivery of AIAG and STAR Core Components

• Modify GM’s development process:– To optimize ROI of WS and collaborations created by Software Factory– To leverage SOA reuse, integration, and migration in outsourced model– To establish a enterprise, SOA team to manage the creation/reuse of:

» WS across each division of IT» BPSS and CPP across trading partners

• Key Production Projects: – Complete ebXML application with an existing Trading

partner using STAR BODS
