Encrypting gRPC Communication with TLS/SSL

When deploying a gRPC service in production, it's important to ensure that the communication between the service and the clients is encrypted. This is why it's critical to ensure that our services communicate with each other via HTTPS rather than HTTP.

With HTTP, all communication between the client and the server is open, which means that it can be read by anyone who is connected to the same network. This will allow any sensitive data to be intercepted by someone other than its intended recipient. When HTTPS is enabled, all communication is encrypted. To anyone who intercepts it, it will look like an unintelligible combination of random bytes. Only the intended recipient can decrypt it and turn it into readable data because only the recipient will have a special key to do so.
