In november 2017 I was on Cloud infra meetup #5 in Warsaw.
Together with Paweł Suder we talked about OVH Public Cloud solutions.
I talked there about how we integrate in OVH OpenStack networking solutions (based on Neutron) with some internal OVH solutions like e.g. vRack.
Lecture was given in polish but slides are available in english.
Slides’ source is available on my Github
