Capacity planning for service-oriented architectures

ABSTRACT

Service-oriented architectures (SOAs) are being increasingly adopted for the development of distributed applications that involve multiple partner organizations. The main challenge in configuring such applications - whether autonomously or manually - is meeting the service quality expected by the consumers.

In this paper, we describe a methodology and corresponding tool implementation for estimating the capacity of alternative configurations of complex service-oriented applications. We use a sophisticated enterprise application with many possible configurations as our test application. The current tool prototype simulates the behavior of the application for a given configuration on an existing network topology. This simulation is relatively coarse-grained, but is capable of tracking several performance indicators. We evaluate this simulation output against actual performance data.
