Dive into the world of gRPC in this 35-minute talk that explores the fundamentals of this powerful remote procedure call (RPC) framework. Learn how gRPC enables client applications to directly call methods on server applications across different machines, simplifying the creation of distributed applications and services. Discover the core concept of defining a service with remotely callable methods, including their parameters and return types. Explore the server-side implementation, where the interface is realized and a gRPC server handles client calls. Examine the client-side architecture, focusing on the stub that mirrors the server's methods. Gain insights into how gRPC facilitates easier development of distributed systems and enhances communication between applications in different environments.
