- Bandwidth: at the very least 1G, recommended for smaller, lower traffic environents is 10G, 25G or more.
- Note: To reduce costs you get away with just having a single interface, instead of, e.g., 2 bonded interfaces, though having 2 will allow for more performance and also the server still being reachable in case of failure.
Use SSDs or any other storage with low latencies (LOW)! ETCD is pretty much latency bound, it needs its “few” IOPS as well but latency is the killer (sequential writing, e.g., WAL and DB).
