Reference metrics for service-oriented architectures

Abstract

This article presents a set of reference metrics for measuring the quality of services in Service-Oriented Architectures (SOAs). It introduces the metrics cube and scalability curve and applies them to the development of service-level agreements (SLAs) and capacity planning. This article also discusses the challenges and approaches for defining and allocating end-to-end metrics in a net-centric environment such as the Global Information Grid (GIG).
