Managed Redis providers for redis-oplog?

A simple question to redis-oplog users: where do you host your Redis instances? I found this list, but I wonder if there are any caveats (e.g. I assume we need a relatively high max number of connections since every user will use one).

I use https://www.compose.com/pricing#redis

It’s pretty affordable, really easy to setup.

We are hosting in redis labs.

redis-oplog knows how to re-use connections for same users

Is anyone using Kamatera? It looks much cheaper than the others.
