Implementing Unary RPC Services with gRPC and Java

Modern distributed systems rely on high-performance inter-process communication. gRPC offers a powerful framework for building fast, efficient microservices, but mastering its core patterns is essential. This course provides a practical, hands-on path to understanding and implementing the foundational Unary RPC pattern using Java. By the end, you will be able to define clear service contracts, generate necessary code, and deploy functional client-server applications. What you'll learn: * Define service contracts using the latest Protocol Buffer syntax for structured data serialization. * Build the structure of a gRPC server in Java capable of handling synchronous requests. * Implement the core logic for Unary RPC methods to process and respond to client calls efficiently. * Configure and use the gRPC client stub to initiate and manage remote procedure calls. * Understand basic concepts of channel security and status code management within gRPC services. The course begins by establishing the foundational concepts of Remote Procedure Calls and Protocol Buffers. We then move into practical implementation, guiding you through setting up the project, defining the service interface, writing both server and client code, and testing the entire communication flow. This course is designed for beginners in distributed systems or microservices development who want to learn how to use gRPC. No prior gRPC experience is required, only basic familiarity with Java programming. Start building high-performance, contract-first APIs today.
