Synchronous Microservices: REST, gRPC, and Communication Protocols

Building a distributed system requires services that talk to each other reliably and efficiently. Understanding how and when to use synchronous communication is the foundation of solid microservices architecture. This course guides you from the absolute basics of microservice boundaries to implementing clean, synchronous communication. You will learn how to design APIs that remain stable under load, select the right protocols for your system, and handle network failures gracefully. What you'll learn: - Understand the fundamental architecture of synchronous microservices and how they differ from asynchronous patterns. - Design clean, scalable APIs using RESTful principles and modern HTTP conventions. - Explore gRPC as a high-performance alternative for internal service-to-service communication. - Apply resiliency patterns like retries, timeouts, and circuit breakers to prevent cascading system failures. - Compare synchronous and asynchronous communication protocols to make informed architectural decisions. You will start with core definitions and architectural concepts before moving on to practical API design principles and real-world failure-handling strategies. The written guide walks you through conceptual implementations and best practices step by step. This course is designed for software developers, aspiring system architects, and tech enthusiasts who want to learn microservices from the ground up, with no prior architectural experience required.
