It depends...

If your services are servicing typical user requests, and expect responses in O(<1s), then eventing architectures are exactly the opposite of what you want. Using message brokers (Kafka) as an ersatz network layer is the path to sadness -- you want backpressure, RPC semantics, etc.

If you're doing ETC/event semantics, the game is different. But very few orgs actually work that way.
