If it is network-based you could just run multiple instances of your process with a load balancer in front. Either software (haproxy, nginx) or an (often expensive) hardware solution. Most cloud providers even have options for running hosted load balancers. Then it is just a matter of doing a rolling upgrade and restart your processes one by one and the load balancer will route around the unavailable processes.
