Building an RPC Framework from Scratch

Distributed systems rely heavily on seamless communication between services, making Remote Procedure Call (RPC) frameworks a cornerstone of modern backend engineering. Understanding how these systems work under the hood is essential for writing efficient, scalable applications. This text-based course guides you through the entire journey of conceptualizing, designing, and implementing your very own functional RPC framework from scratch.\n\nBy building this system step-by-step, you will transition from using black-box libraries to deeply understanding network protocols, serialization, and distributed communication. You will gain practical architectural insights that will elevate your backend development and system design skills.\n\nWhat you'll learn:\n- Understand the foundational concepts of RPC, microservices architectures, and network communication\n- Design custom communication protocols and implement efficient serialization and deserialization\n- Build robust network, server, and client modules to handle remote requests seamlessly\n- Implement modern asynchronous patterns and connection pooling to optimize performance\n- Create a distributed calculator application to test and validate your custom framework in a realistic scenario\n- Analyze architectural challenges, performance bottlenecks, and real-world optimization strategies\n\nYou will start with core theoretical definitions and protocol design before moving step-by-step through module development, culminating in a complete, working distributed application. This course is designed for backend developers, software engineers, and system designers who want to demystify distributed systems, with no prior RPC development experience required. Begin reading today to master the underlying mechanics of distributed microservices.
