Definitions

Service Oriented ArchitectureService Oriented Architecture (SOA) is

an architectural concept where software functionalities are exposed as services.

Service

A Service is a software component designed to be invoked by name across applications or across organizations via a well-defined interface

SOA Attributes

Benefits

Characteristics

Smaller software components, and greater reuse of standard software through plug and play approach

Heavily dependent of use of industry standards and a robust network

Business flexibility provided by increased granularity of processes enabled through services

Ability to quickly create business processes and composite applications to respond to changes in the marketplace

Decrease development and deployment cycle times through the use of pre-built, reusable services building blocks

• 1970 - 1980’s● Monolithic applications● Mainframe ~ dumb terminal● Little integration, Applications in functional domains

• 1990’s● Distributed applications● Client ~ server● Integration within functions domains / application suites ~

proprietary• Early 2000’s

● Loosely Coupled Applications● Web enabled● Integration using proprietary middleware and some web services

• Late 2000’s● Composite applications● Rich web clients / portals● Standards based integration and orchestration

What is Really Different

By 2008, Gartner predicts that SOA will be a prevailing software-engineering practice, ending the 40-year domination of monolithic software architecture

Industry Trends

Gartner● “By 2006, more than 60 percent of enterprises will consider

SOA a guiding principle in designing their new mission-critical business applications and business processes (0.7 probability)”.

● “By 2006, more than 75 percent of midsize and large enterprises will have deployed SOA-enabled development tools and middleware (0.8 probability)”

● “Services-oriented development will dramatically increase in near future.”

Applications& Data

Application functions are built as components (or "services") that are loosely-coupled andwell-defined to support interoperability, and to improve flexibility and re-use

XVL

• Develops standards-based XVL® 3D format– Provides 1/50-1/200 compression of 3D images

• order of magnitude better than currently available

– XML-based format fuses visual and non-visual data – Works with major CAD/CAM systems – Highly accurate

• Leverages 3D data across the enterprise by XVL®– Speeds development & design cycles – Allows departments and partners collaborate – Enables automation and reduces costs for improved Manufacturing,

Customer Service, Marketing, etc.

Future

• Agile systems that adapt quickly to changing markets and process requirements

• Incorporation of new technologies:– Web Services

• XML, HTTP, SOAP

• Service Oriented Architecture• Model Driven Enterprise• Process Orchestration along Supply Chain• IT Skills to Support New Environment

The Future Has Never Been More Exciting And Challenging
