I encountered "process as proxy" today dealing with Cisco. We were requesting a replacement for a defective part, they asked us for our serial number, which we provided, but then responded to us that our serial number was invalid. Likely because it wasn't registered. We were told that we had to contact our sales manager, or open a TAC with a different department because they department only deals with technical issue…
Yes, they could have provided an orchestrating microservice.
But they did a good job. Tech issues microservice should not have knowledge of other departments.
