Web Services Market Today Evolution of Application Integration over the Internet Market is not clearly defined

Open Standards are making progress

Web Service Business Issues Resolve IT department bottlenecks Enhance Cost Efficiency with existing infrastructure

Web Services Economic model evolves A few highly skilled leading-edge companies seek to enable

development and integration The Big Platform and Software Players look to integrate WS into product line

Gartner predicts Market size to exceed $1.7 billion by 2002

SOA Benefits for GM IT Cost Savings

Accomplish more with development budget Services reuse is aimed at GMs 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 complementaryarchitectures:

J2EE + WebServices + ebXML Increased competition among product vendors and

software development vendors

Purpose: Define GMs Application Architecture and ITStandards for SOA; Evangelize

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

Approach: Enterprise-level IT provides SOA technologyand methodology leadership

Funding: Application Solutions Delivery corporate budget Key contributors: BEA, IBM, New Era of Networks and Sun GMs 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

When to Consider ebXML B2B or large A2A EnvironmentsExtending or integrating

enterprise SOAs, or when loosely coupled messaging is desirable Need Reliable MessagingWhen enterprise services perform

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

Security is a ConcernWhen different security profiles andrequirements exist between trading partners

High scalability requirementsebXMLs loosely coupledmessaging architecture allows for horizontal scalability, queueing,

and clustering Want to Leverage Industry StandardsXML 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

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 GMs 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
