Service-oriented infrastructure

Infrastructure Architecture is regarded by many as one of the three pillars of Information Technology, together with Business Architecture and Application Architecture. Service-oriented infrastructure results from applying the principles of service-orientation to this architectural pillar.

It is related to Service Oriented Architecture (SOA) which is most commonly used to refer to the use of this principle in Application Architecture. A Service-Oriented Infrastructure forms an appropriate foundation for a service-oriented Application Architecture (and for other styles of application architecture also), and can be regarded as a natural part of a service-oriented Enterprise Architecture.
