OTP Servers and Concurrency Essentials

Mastering OTP servers is essential for building scalable, fault-tolerant applications in concurrent systems. This text-based course guides you through the foundational principles of OTP server architectures, helping you confidently understand, write, and evaluate concurrent processes. You will begin with essential terminology, process isolation, and message passing before exploring gen_server implementation, process state, and basic supervision concepts. Through structured reading material, clear code snippets, and self-assessment questions, you will develop a practical understanding of OTP behaviors. What you'll learn: • Understand core OTP terminology, process isolation, and actor-model concurrency. • Implement gen_server callbacks including init, handle_call, handle_cast, and handle_info. • Manage process state safely across synchronous and asynchronous interactions. • Apply fundamental supervision patterns to handle process failures effectively. • Analyze process flows and evaluate code logic through practical written exercises. The course starts with foundational definitions and moves step by step into core server mechanisms. Designed for beginners and developers new to OTP, no prior experience with concurrent systems is required. Start reading today to build a strong foundation in OTP servers.
