Service-oriented architecture (SOA) middleware has emerged as a
powerful and popular distributed computing paradigm due to its
high-level abstractions for composing systems and hiding
platform-level details. Control of some details hidden by SOA
middleware is necessary, however, to provide managed
quality of service (QoS) for SOA systems that need predictable
performance and behavior. This paper presents a policy-driven
approach for managing QoS in SOA systems. We discuss the design
of several key QoS services and emperically evaluate their
ability to provide QoS under CPU overload and
bandwidth-constrained situations.
