I need to deploy a highly available Docker Swarm on Azure. I created a VNet in 3 locations: Brazil South (my location), East US and West Europe. Then I enabled network peering so VMs in these locations can see each other as if they were in the same VNet. Cluster seems working fine. The problem is that turns out latency is high between these locations: ~190ms.
- Is this a recommended topology for HA? Is there a way to improve it?
- Will this latency pose any (future) limitations?
