VM to VM communication, same network, different compute hosts

In the last post, we spoke about VM to VM communication when they belong to the same network and happen to get deployed to the same host. This is a good scenario, but in a big openstack deployment, it's unlikely that all your VMs belonging to the same network will end up on the same … Continue reading VM to VM communication, same network, different compute hosts

VM to VM communication: Same network & same compute host

In a physical world, machines communicate with each other without routers when they belong to the same network. This is the same case with openstack, VMs communicate over the same network without routers. When two VMs belonging to the same network happen to get deployed on the same compute host, their logical diagram looks like … Continue reading VM to VM communication: Same network & same compute host
