Hi Voytek, I looked into this a little while ago, and couldn’t really find a definitive answer. We ended up keeping the GossipingPropertyFileSnitch in our GCP Datacenter, the only downside that I could see is that you have to manually specify the rack and DC. But doing it that way does allow you to create a multi vendor cluster if you wished in the future.
I would also be interested if anyone has the definitive answer one this.
