Abstract : Modern distributed systems are characterized by a growing complexity of their architecture, functionalities and workload. This complexity, and in particular significant workloads, often lead to quality of service loss, saturation and sometimes unavailability of on-line services. To avoid troubles caused by important workloads and fulfill a given level of quality of service (such as response time), systems need to self-manage, for instance by tuning or strengthening one tier through replication. This autonomic feature requires performance modelling of systems. In this objective, we developed a framework based on a theoretical and experimental approach for automatic identification process and sizing . This framework provid a queuing model for a distributed system. Then, this model is used in our Framwork to size the system through an analysis or simulation.
