Agenda

Why the need for service oriented architectures (SOA)– IT Challenges

What is SOA and Web services– Elements of SOA– Benefits of SOA– Business Opportunities in SOA

Oracle’s solution for SOA– Tools, Application Servers, Database, Portal, Integration– Customer case Studies of SOA– 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

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– Across programming languages– Across hardware and O/S platforms– Across computing platforms (J2EE, .NET)

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
