Service-Oriented ArchitectureToday and Beyond

A service-oriented architecture is a style of multi-tier computing that helps organizations share logic and data among multiple applications and usage modes.

Gartner, “Service Oriented Architectures”, 1996

Service-oriented architecture is a best-practice architecture pattern for the systematic design of request/reply applications. Its primary intentions are business-level software modularity and rapid, non-intrusive reuse of business software in new runtime contexts.

Gartner, “Introduction to Service Oriented Architecture”, 2003

Service-oriented architecture is a design style for maximizing service sharing, reuse, and interoperability in distributed environments.

Burton Group, “Service-Oriented Architecture: Developing the Enterprise Roadmap”, 2004

A service-oriented architecture is a framework for integrating business processes and supporting IT infrastructure as secure, standardized components – services –that can be reused and combined to address changing business priorities.

IBM, “Service-Oriented Architecture (SOA) Compass”, 2006
