Performance and QoS in Service-Based Systems
R. William Maule, William C. Lewis · 2011
We present a systematic method of measuring performance risk for specific implementations of an Enterprise SOA within a Cloud computing framework. The U.S. Department of Defense (DOD) is determining performance baselines for distributed architectures that are internally organized using service interfaces. Such architectures are essential for highly reliable and life critical Cloud applications. We provide baseline performance for an architecture comprised of service components from the service interfaces provided by several major commercial software vendors. Transition from legacy systems into Service-Oriented Architecture (SOA) systems necessitates an infrastructure of federated components. This paper documents a means to measure such an infrastructure. Baselines provide a foundation for assessment of future services including Quality of Service (QoS) contracts and assessment of fused web services within heterogeneous SOA or Cloud architectures.
