  services

11
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 complementary
  architectures
• J2EE WebServices ebXML
• Increased competition among product vendors and
  software development vendors

12
Software Factory Enabler Project

• Purpose Define GMs 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
• 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

13

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, reliable messaging becomes
  critical
• Security is a ConcernWhen different security
  profiles and requirements exist between trading
  partners
• High scalability requirementsebXMLs loosely
  coupled messaging architecture allows for
  horizontal scalability, queueing, and clustering
• Want to Leverage Industry StandardsXML grammars,
  business process modeling and trading partner
  agreements
