A Meta-Model for Performance Modeling of Dynamic Virtualized Network Infrastructures
The increasing popularity of Cloud Computing is leading to the emergence of large virtualized data centers hosting increasingly complex and dynamic IT systems and services. The performance of applications running in such data centers depends on the performance of three main subsystems: computing, storage, and networking. In this paper, the authors present a new meta-model designed for the performance modeling of dynamic data center network infrastructures. Their approach models characteristic aspects of Cloud data centers which were not crucial in classical data centers. They present their meta-model and demonstrate its use for performance modeling and analysis through an example, including a transformation into OMNeT++ for performance simulation.
