In a distributed monolith or microservice architecture, what are options to RPC between Web Apps, Container Instances and Function Apps?
I am aware of HTTP based (REST or gRpc) which are not Services per se. Everything else I am aware of is Request/Reply or a Queue(Service Bus).
Struggling to explain why I am asking this question to forestall low quality comments. I am guessing the answer is because there is not much value to be added to wrapping an HttpClient. But a solution that uses local-to-azure network addresses alone would be useful. I would be very happy to hear an answer with a product that I am not aware of.
