Overview of Service-Oriented ArchitectureOverview of Service-Oriented Architecture

What is SOA?

• Service-Oriented Architecture (SOA)– Effective approach to distributed computing

• Emphasis on software services– A service is a large unit of functionality– E.g. Viewing your bank statement online

• Applications are composed of services– But without embedded calls to one another

• Combines existing software services to solve problems• Re-use at the service level

– vs. the object level• SOA Principles

– Loosely coupled– Service Contract (implemented through WSDL)

Web Services

• An SOA is frequently implemented through Web Services

• Web Services interoperate over a network– The Internet– Intranet

• Core Specifications– SOAP– Web Services Description Language (WSDL)– Universal Description, Discovery,

and Integration (UDDI)

Provisioning Standards Support from the Vendor Community

• Service Provisioning Markup Language (SPML)– OASIS standard to address the interchange of service

provisioning requests

• Directory Services Markup Language (DSML)• Vendor support

– Microsoft, PeopleSoft, Sun (IDMS)– HP, IBM, Oracle, SAP, Siebel
