Building High-Performance APIs with gRPC and Spring Boot

Modern enterprise architectures demand fast, reliable, and low-latency communication between microservices. Traditional REST APIs often fall short under heavy loads, making high-performance alternatives essential for modern Java developers. This text-based course guides you through transitioning from standard HTTP APIs to high-performance gRPC services using Spring Boot. You will read and learn how to define strict service contracts, generate Java code automatically, and build robust microservices that communicate with minimal overhead. What you'll learn: - Understand the core architecture of gRPC and how it differs from REST - Define structured data schemas and service contracts using Protocol Buffers - Configure Spring Boot applications to host and consume gRPC services - Implement unary, server streaming, client streaming, and bidirectional streaming patterns - Apply modern testing practices to validate gRPC endpoints using JUnit - Secure microservice communication using transport layer security and interceptors You will start with the fundamental concepts of Remote Procedure Calls and Protocol Buffers before moving step-by-step through setting up, coding, testing, and securing your first production-ready gRPC services. This course is designed for Java developers new to gRPC; no prior experience with Protocol Buffers is required, though a basic understanding of Spring Boot is helpful.
