Why is Metal not offered for single instance deploys? Our app does not need this kind of uptime. We would be happy with a node going down once in a while (no data loss, of course) with a little bit of downtime to save 66% on the cost of running 2 additional nodes that will never see action.
It's a durability thing, we need to make sure writes are replicated off to at least one node. There might be avenues to get Metal down to single node in the future.
