The paper presents an approach to modelling and simulation of web systems. The systems are being modelled from the point of view of services realized by them. The formal model of a system, accompanied with a model of a request realization is presented. The main aspect of the paper is a simulation model of client-server interactions that adequately describes the relationship between the server response time, its availability and resource utilization. The model was constructed based on the the results of multiple experiments presented in a paper. Moreover, it was implemented in the simulation tool and its accuracy verified against testbed web servers. Apache and IIS servers were analysed.
