“…The approach is based on service behavior metrics and on a methodology for guided analysis which uses data mining to find the root causes of service malfunction. Finally, the following studies apply dynamic simulation techniques: [11] puts forward a dynamic model which helps manage the delays that occur in the processes where there is a certain degree of uncertainty regarding their causes. The proposed model in [12] is applied to deal with the problem of deciding on how to allocate resources in order to guaranteee SLAs fulfillment.…”

Abstract-This paper presents a dynamic simulation model applied within the field of web services capacity management. The main purpose of the model is to help manage the web services capacity that providers assign their customers accordingly so as to ensure the fulfillment of the Service Level Agreements (SLAs) established.Therefore, the model allows for the analysis of the effects of different web services capacity management polices on the service performance and on the penalties to be assumed by providers for non-compliance with the response times agreed with their customers. The main aims of the sensitivity analysis carried out in the case study of this research paper are as follows: (1) to assess the fulfillment of the SLAs according to the web service capacity contracted by the customer, (2) to determine the lowest web service capacity and those capacity management parameters that ensure that the actual service performance is the one that has been agreed on (3) to evaluate the penalties that the web service provider should assume for non-compliance with response times.

“…We extend the previous work on applying system dynamics to (atomic) service provision management [8], by deriving the quantitative indicators for a service provision chain (number of executing instances, invocation and failure rates) from the structure of a particular composition being provided, as well as from a model of computational resources involved in provision. Usefulness of the system dynamics approach for generating simulators of different (and potentially complex and "non-standard") what-if scenarios that reflect interesting situations in provider's environment, has been already studied [9]. Such simulators can be used as a basis for developing and validating provision management policies for service-oriented systems.…”

“…The former has been studied in several interesting, but specific, cases [9,10], and some examples of a more systematic approaches to building such dynamic composition models based on QoS constraints have been demonstrated [11]. Our intention is to propose a generic method of converting descriptions of orchestrations in the form of a place-transition networks (PT-nets) [12] into dynamic models, in a manner that ensures composability of orchestrations within choreographies.…”

Abstract. 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.
