In CloudFoundary the only way to work with WebSockets, in a MultiNode setup, is to inform the other Node via the Database. This is a very costly way because you constantly have to query the database in order to see if a new Websocket-call exists. Since Mendix is moving to Kubernetes it would be nice to have the possibility to inform the other Node directly.
You can use external services for this, but this would result in extra license-costs.
Since WebSockets gives applications additional capabilities, it would be great if the functionality described above could become part of the Mendix platform.
