Network Programming in Go: Building Concurrent TCP Servers

Modern backend applications rely heavily on fast, reliable, and concurrent network communication. Understanding how to build network services from the ground up is a crucial skill for any developer looking to write high-performance systems. This course guides you through the process of building a fully functional, concurrent TCP server in Go. You will transition from understanding basic networking protocols to implementing robust concurrency patterns that can handle multiple client connections simultaneously. What you'll learn: - Understand foundational networking concepts, TCP/IP basics, and how sockets function - Configure a Go project from scratch using modern Go modules for dependency management - Implement a TCP server using the standard library net package to accept incoming connections - Apply Go concurrency primitives like goroutines and channels to handle multiple clients simultaneously - Manage connection lifecycles and timeouts safely using the context package - Write structured tests to verify your server's behavior under simulated client loads You will start with essential networking terminology and protocol definitions before diving into Go's standard library. Step-by-step written explanations and code exercises will lead you through setting up your server, managing concurrent client routines, and handling graceful shutdowns. This course is designed for beginner Go developers who want to learn network programming, requiring no prior experience with TCP or socket programming.
