gRPC: High-Performance APIs for Distributed Systems
gRPC is Google's open-source remote procedure call framework built on HTTP/2 and Protocol Buffers. Unlike REST, it uses a strongly typed contract defined in .proto files, supports bidirectional streaming, and delivers significantly lower latency and smaller message sizes — making it the default choice for inter-service communication in serious microservices architectures. This track covers gRPC from first principles through production-grade deployment patterns.
What You Will Learn
You will start with gRPC fundamentals and the role of Protocol Buffers, then build your first service from scratch. From there you will work through the four gRPC communication patterns — unary, server-streaming, client-streaming, and bidirectional streaming — alongside error handling, status codes, and metadata propagation. Later courses address TLS and authentication for securing services, observability (tracing, metrics, logging), cloud integration, and advanced Protobuf techniques including schema evolution and backward compatibility. The track closes with microservices architecture using gRPC and real-world case studies drawn from production systems.
The Learning Path
Twelve courses span A1 to C1. The first course is free and introduces gRPC concepts and API fundamentals. Early courses (A1–B1) cover service setup and core communication patterns. Mid-track courses (B2) go deeper into security, the gRPC ecosystem and tooling, observability, and cloud service integration. The final four C1 courses — Performance Optimization with gRPC, Advanced Protobuf & Schema Evolution, Microservices with gRPC, and Real-World gRPC Case Studies & Patterns — tackle the problems engineers face when running gRPC at scale in production.
How It Works
Each course is split into short, hands-on lessons you complete in the built-in code editor with real-time feedback. An AI tutor is available whenever you get stuck, and the progression is designed so each concept builds directly on the one before it.
