This course introduces you to gRPC, a high-performance and open-source framework for remote procedure calls (RPCs) that supports fast, scalable communication between distributed services. gRPC is widely used in microservices architectures and is designed for real-time, low-latency systems. You’ll learn the fundamentals of gRPC and how it uses Protobuf to define services and serialize structured data. The course then covers the four types of RPCs: Unary, Server Streaming, Client Streaming, and Bidirectional Streaming, along with practical examples of when to use each. Next, you’ll implement gRPC in Java using client stubs. You’ll define services, build and test a gRPC server and client, and set up secure communication with SSL/TLS and authentication with hands-on exercises. By the end of the course, you will understand how to build efficient, secure, and scalable applications using gRPC in Java. These skills are valuable for back-end development and working with distributed systems.
