Will it autoscale database ram/disk and instances? Specifically will it autoscale instances and work if I create a simple replicaset of one node for the oplog alone? It doesn't support creating replicaset of 1 in interface, so I worry that it will not detect replicaset to add nodes to.
It just scaled down to 3 droplets, which amounts to just 15 usd, much better than where it was before.
