Evaluation of traffic-aware VM placement policies in distributed cloud using Cloud Sim

Due to the complexity of managing virtual machines arrival and departure in a geographic distributed Cloud, we tackle the dynamic placement and migrations of VMs with simulation techniques. In this work, we present the study of VMs placement policies in geographically distributed data centers (DCs) using the cloud simulator Cloud Sim. We have extended the simulator to take into consideration the inter-DCs communication and migration. Through simulations, we show an example of aVMs placement and migration approach and discuss the obtained results.
