You can add these option to your .proto (base on your language) to generate abstract services:

option cc_generic_services = true;
option java_generic_services = true;
option py_generic_services = true;

You can also add --plugin=EXECUTABLE option in your protoc cmd to use custom code generator plugin to generate code more specific to each system, rather than rely on the "abstract" services. Just like Eric's suggestion.
