A Simulation Test-bed for the Design of Dependable e-services
Panagiotis Katsaros, Constantine Lazos · 2003
Abstract:- In this paper, we present the design and development of a simulation test-bed, for the performance analysis of dependable and mission critical e-services. Key characteristics of such systems, like for example, the object state transfer and recovery policies to be applied together with the chosen load distribution strategy, play the determinant role in the service’s performance and customer response perception. Analytic models usually fail to realistically capture the effects of the available design alternatives. On the other hand, the published simulation studies are usually bound to algorithms, which are not covered by the recently published standards, for the development of object based services. Our work aims to provide a comparison framework that adheres to the published standards, allows the compositional development of the service configurations of interest and the estimation of meaningful performance measures, in an efficient way.
