Transaction Profile Estimation of Queueing Network Models for IT Systems Using a Search-Based Technique

Conference paper
Part of the Lecture Notes in Computer Science book series (LNCS, volume 8636)

Abstract

The software and hardware systems required to deliver modern Web based services are becoming increasingly complex. Management and evolution of the systems requires periodic analysis of performance and capacity to maintain quality of service and maximise efficient use of resources. In this work we present a method that uses a repeated local search technique to improve the accuracy of modelling such systems while also reducing the complexity and time required to perform this task. The accuracy of the model derived from the search-based approach is validated by extrapolating the performance to multiple load levels which enables system capacity and performance to be planned and managed more efficiently.
