19 Dec 2005 Listen to this informative interview with two experts in service-oriented architecture (SOA) implementation. Seventh in the WebSphere® Technical Podcast series on developerWorks, this 19-minute podcast covers what to consider when deploying the SOA operating environment in your IT system. It discusses the four key principles of an SOA operating environment: separation of concerns, loose coupling, reuse, and quality of service.

This podcast covers what you need to know about deploying in a SOA operating environment: - The SOA operating environment provides the principle of separation of concerns to create loosely coupled, reusable services on a stable, predictable, and flexible IT infrastructure.
- The reduced complexity from separation of concerns and increased modularity allow for quicker delivery of products and reduced maintenance issues.
- Loose coupling refers to the dependency between systems. The three important dimensions are technology, temporal, and implicit.
- Of the different types of reuse (component-level, application-level, and service-level), service-level reuse offers the most compelling level of reuse. To truly realize service-level reuse, organizations must get better at component-level reuse, especially on a larger scale.
- Measuring the quality of the deployment requires that the deployed business processes, service interfaces, and underlying operational systems are allowed to provide real-time feedback of key performance indicators (KPIs).
- In response to requests from customers and Independent Software Vendor (ISV) partners, IBM® is jointly delivering two specifications for building systems that use a SOA: Service Component Architecture (SCA) and Service Data Objects (SDO).
