Efficient and competitive provision of service compositions depends
both on the composition structure, and on planning and management of computational
resources necessary for provision. Resource constraints on the service
provider side have impact on the provision of composite services and can cause
violations of predefined SLA criteria. We propose a methodology for modeling
dynamic behavior of provider-side orchestration provision systems, based on the
structure of orchestrations that are provided, their interaction, statistically estimated
run-time parameters (such as running time) based on log traces, and the
model of resources necessary for orchestration provision. We illustrate the application
of our proposed methodology on a non-trivial real world example, and
validate the approach using a simulation experiment.
