I don't really think of route based "load balancing" as load balancing. That's routing, or a reverse proxy. Not load balancing. Load balancing is a very specific type of reverse proxy.

The point is, if a client makes a request to a server, the response should always be the same, no matter where the load balancer sends the request to. Which means it should run the same code.

Nginx doesn't even mention route based or endpoint based load balancing in their docs. Maybe they don't consider it load balancing either.

Describes exactly what I’m talking about.

That is still routing. Not load balancing. The load balancing is only between pods of the same service.

Just because Nginx is doing it, doesn't mean it's load balancing. It's an extra function tacked onto a load balancer.
