The video tutorial guides viewers through implementing a sum function using gRPC. It starts with setting up a new package and defining the necessary syntax. The tutorial then covers defining the calculator service and its messages. Next, it explains how to implement and start the server. The video continues with implementing the calculator service by overriding the sum function and handling requests. Finally, it demonstrates creating a client to test the sum function, ensuring the server and client communicate correctly.

Explain how the server is started in the calculator service implementation.

What is the purpose of the response observer in the sum function implementation?

How do you create a calculator client and what is its main function?
