Erlang and Elixir OTP Applications: Theory and Practice

Building highly available, fault-tolerant systems requires a deep understanding of the Open Telecom Platform (OTP) framework. This text-only course guides you from the fundamental concepts of concurrent processes to structuring complete production-ready applications. You will learn how to design robust systems that can self-heal and scale seamlessly. Through clear written explanations, structured code walkthroughs, and conceptual quizzes, you will master the mechanics of supervision trees, application behaviors, and state management. What you'll learn: Understand the core philosophy of OTP and the 'let it crash' mentality; Configure supervisor strategies to build self-healing process hierarchies; Manage state and asynchronous tasks using GenServer and Agent behaviors; Structure and package your code into reusable OTP applications; Practice debugging and monitoring concurrent processes using modern observability concepts. The course begins with foundational definitions of processes and actors, gradually moving toward advanced application configuration and release packaging. This course is designed for software developers who are new to Erlang, Elixir, or the OTP framework, requiring only a basic familiarity with programming concepts.
