Anything but Zookeeper! It was written long before the cloud was a thing, relies on hard-coded IPs, and is practically impossible to operate idiomatically in a cloud environment (unless you’re using statefulsets in K8S to paper over it). It has served us well over the past two decades, but it’s nigh time to give it the proper burial ceremony it deserves.

ZK in statefulsets can still get wedged super hard, especially if you power cycle all the nodes. It's pretty unpleasant.
