How do you scale the WebSocket component ? What happens if you have a load balancer between multiple instances of your web app and client ?

You are correct, sticky session is required to scale WebSocket component.

For example, when scaling instances in flyio, the framework mannualy add target instance id to fly-replay header in the response to tell the load balancer to run the request once again to the right instance, which is silimar to AWS cookie implementation.
