Seems like the extreme version of this would be a simple annotation in client code to run it on the server, like the old <script runat...> in ASP, e.g. Java pseudo code @RunAt(Platform.SERVER) public Observable<List<Customer>> findCustomersByName(String name) { return // code to query DB and return a list of customers over the wire } // on client public void searchByCustomer(String name) { // findCustomersByName() and bind stream to UI } The idea being that the RPC is automatic here. The client code makes an async call, constructs an observable around deserialized result. The server code is pulled out by and spun up as a cloud function on demand. Of course this only makes sense if the code needs to run on the server (e.g. the results are big and need to run a lot of code, or need to run code that can't be trusted on the client).
