That should be good. The two main things to think about are: 1. etcd stores keys in RAM (and snapshots to disk), so you need enough of that for your data set 2. etcd doesn’t serve a successful write until it is written to disk on a quorum of machines, which means it is IOP-sensitive. Larger instances generally get more IOPs. SSDs will help here too.
