OpenStack Day France 2017

Latency is a critical requirement for Internet Of Things and NFV/SDN applications that favors a more distributed Cloud Computing model deployed at the Edge. This model does not cope with the traditional vision that has been driving the development of OpenStack. Hence, the question of using OpenStack to operate Fog, Edge and NFV infrastructures is often debated due to potential performance/scalability issues. Although some efforts such as OpenStack multiple regions and Cells may allow operators to administrate these new infrastructures, there are no studies that evaluate how OpenStack will behave in such a massively distributed context.

This talk presents results of a study focusing on the impact of Wide Area Network communications on real OpenStack deployments. To this aim, we developed the Enos framework[1][2] to achieve reproducible performance experiments while doing traffic shaping. Experiments of this talk have been done over the Grid'5000 and Chameleon testbeds.
