How to get started?
IT Challenges
 Applications are monolithic
–
–
–
Discrete steps supported by single application
Applications are brittle and are not easy to adapt
Applications are hardwired to presentation devices
 Complexity of heterogeneous technology
–
–
–
Interactions within and across enterprises are difficult
Based on proprietary standards & technology - No
Interoperability
Difficult to connect to a large number of applications
 Applications operate as inflexible silos
–
–
Difficult to build end-to-end business processes
Difficult to adapt business processes
The Answer…
 Applications are monolithic
–
Build applications as services
 Complexity of heterogeneous technology
–
–
–
Do not create “yet another platform”
Deploy on standards based platforms
Use interoperable technology
 Applications operate as inflexible silos
–
–
Integrate services to event-driven business processes
Compose business processes rapidly and adapt to
changing requirements
Services Facilitate Reuse

Service Oriented Architecture
(SOA)
 “Service-oriented architecture is a style of
multi-tier computing that helps organizations
share logic and data among multiple
applications and usage modes”
 Web Services enable an interoperable SOA

Web Services Versus Web
Applications
Web Services
 XML/SOAP
 Program-to-program
interaction
 Static or dynamic
integration
 Re-usable service
Web Application
 HTML
 User-to-program
interaction
 Static integration of
components
 Single use service

Databases
Application Server
 Application Re-Use
 Enables sharing of business logic
 Shields developers from mode-specific presentation
Case Study: Dell
 Dell Business Model
–
–
–
Direct material purchase represent 70% of revenue
Inventory asset exposure – prices drop 0.6% per week
Need effective supply chain planning
 Dell’s challenges
–
–
–
Dell ships in 5 days, replenishes inventory in 45 days
Dell maintains an inventory that lasts about 30 hours
Manage large number of product transitions every year
Business Opportunities: Dell
 Dell’s Solution: Vendor managed hubs
–
–
–
–
–
Dell uses Web services based event management
Dell publishes a production schedule every 2 hours
using web services
Vendors’ Inventory management systems determine
what is needed for shipment
Vendors pick, pack, and ship in 90 minutes to Dell’s
manufacturing units
Dell has no stock rooms now, 2 hours of inventory
Oracle’s Web Services Strategy
 Make Web services pervasive
–
–
Embed Web services across the infrastructure
Interoperate based on industry standards
 Build Web services on J2EE and XML
–
–
Maximize productivity, minimize retraining
Inherit performance, reliability, security of OC4J
 Deliver simple and business Web services
–
Enable business process based Web Services

Where do I Start?
 Look at existing technology investment and
determine where Web services will add value
 Look for low risk high benefit projects that do not
disrupt existing operations
 Focus on projects with short timelines and clear
deliverables.
 Develop deep understanding of the state of web
services
–
Decide which standards are appropriate for your
enterprise
 Build out an entire Web services architecture
