A Beginner’s Guide to Secure gRPC Communication in Python

I have been trying to understand the evolution and proper use cases of gRPC. If I try to simplify this, gRPC is a specific and modern implementation of RPC that offers advantages such as

• efficient data serialization,
• HTTP/2 support,
• language-agnostic interfaces,
• built-in support for transport security (TLS/SSL) and authentication in gRPC,

and others.

If you are wondering about the differences between RPC and RPC:

Basic Difference with RPC and gRPC

It has gained popularity, especially in microservices architectures and cloud-native applications.

In this article, I am going to share a basic gRPC application built using Python with a unidirectional data flow. The architecture will be:

A very basic architecture of the application: movie_service

Background of the Application

• 3 services are involved in this movie_service demo application.
• movie_gateway_service: This is mostly the entry point of the application.
  This service has three important endpoints
  1. /rest/get_movies
  2. /grpc_secured/get_movies
  3…
