For that mater, Redis/Valkey is relatively easy to stand up... I almost don't give it a second thought to stand up Redis, and I'll generally reach for an MQ library that's using Redis over the dbms more often than not... Mostly in that, by comparison setting up Rabbit or Kafka gets a lot more complex.

What I don't always "get" is Redis as a persistent database, such as with the "LamerNews" codebase (which EchoJS uses), so that use case still feels a bit alien to me, and I'm surprised it works as well as it does.
