Abstract: Resource virtualisation can enhance resource availability to the offered services in cloud computing. Modelling of virtualised resources for dynamically changing workload is an important problem to be tackled, so as to design and develop resource management algorithms. This paper presents modelling of resource virtualisation concept for cloud computing scenarios based on the formalism of finite state machines (FSMs). The resources considered in our model are processors and primary memory; however, the model can also be applied to other resources like storage and network devices. The basis for description of model behaviour is communicating extended FSMs that are represented by systems, blocks and processes. The proposed model is used to analyse the impact of loads on virtualisation in cloud computing by using Cindrella SDL tool. It is observed that resources are allocated depending on the availability without any deadlocks and terminations. The model can serve as the foundation for development of resource allocation, resource brokering, resource security, resource provisioning, and resource adaptation protocols in cloud computing.
