Even simpler is Weighted Rendezvous Hashing (https://www.snia.org/sites/default/files/SDC15_presentations...).

It's quite a bit easier to implement and verify than consistent hashing, and carries the same benefits (minimal reshuffling on ring resizes, etc)

In a similar vein, Maglev hashing has a more uniform distribution and decent reshuffling. I couldn't get my head around the explainaions that I had seen until I read this one:

I recently updated the Python example on the Wikipedia page for Weighted Rendezvous Hashing. (I'm amazed my edit seems to be still there.)
