Hey, I'm looking into setting up openstack in a minimal "production" environment with 2 all in one nodes for swift and nova. First I wanted to ask if you would advise against it or if it should be fine? The plan is to have 2 zones with one all in one node for swift and nova each as a starting point and then work from there on (later scale out to more nodes). As an immediate failover solution, I wanna use rackspace. (failover handled via scalr [but not sure yet])
The problems I see are: First useful to have a minimal setup like this? (both nodes have 16gb ram and 8 cores and 4tb diskspace). Third node available with minimal network connectivity/speed. Second, which is probably the essence of this mail. I'm not controlling the network layer. There are no floating IPs, cause IPs are bound to each server via mac address. I can't trust the network traffic. The provider is hetzner.de, if someone is familiar. Is there any solution to that? Perhaps I just missed it in the docs. I thought about using a vpn mesh network to setup a virtual network and running openstack on top. Still the entry points of the vpn would be the bottleneck and the performance would go down a lot I reckon. How would one run an openstack cloud/cluster across more than one datacentre? Is there a way without bridging the datacentres via vpn or direct link? Thanks for any help/hint/idea. Cheers Michael
