Tbh I don't have the experience to give advice or reviews. That said, check out Nats.io. It's basically just a messaging system but it's beautifully abstracted, horizontally scalable and runs locally from a small binary. It largely removes the need for much middleware like load balancers. They've also recently added persistence features for streams and KV stores. It doesn't solve every problem but I do think a message system is a very good core abstraction to build other things on top of.
