I'm curious to hear what your experience with NATS will be. We haven't played with it. I do know that a ton of the work that went into Finagle was around resilience at scale: things like backpressure, circuit breaking, and generally tolerating slow, bad, or flapping servers. Personally I would want to see that sort of thing in any RPC system before using it at scale.

We're a small shop; each of our clusters are currently a couple dozen static servers at most. So we don't really do anything at what would be considered "at scale". For us, developer ease of use and performance is a higher priority.

But we're slowly moving towards a setup where we'll likely rely on autoscaling, and where we will likely need a more robust architecture.
