Erlang and OTP: Foundations for Concurrent Systems

Modern applications require extreme reliability and the ability to handle millions of simultaneous processes without crashing. Erlang was designed specifically to meet these demanding requirements. This course guides you from the fundamental functional concepts of Erlang to mastering the Open Telecom Platform (OTP) framework. You will gain the foundational knowledge required to design and implement highly available, concurrent, and fault-tolerant software systems. What you'll learn: * Understand the immutable data structures and functional programming paradigm of Erlang. * Master the Actor model and lightweight process concurrency without shared memory. * Apply standard OTP behaviors like gen_server and supervisor for structure and reliability. * Configure supervision trees to automatically detect and recover from process failures (fault tolerance). * Practice setting up basic distributed Erlang nodes for inter-process communication. * Implement basic unit tests using standard Erlang testing frameworks to ensure code correctness. We begin by establishing the core syntax and unique concurrency features before diving into the practical application of the OTP standard library. The material focuses on reading and writing clean, reliable, and production-ready Erlang code. This course is designed for programmers new to Erlang and functional programming who want to build resilient backend services. No prior experience with Erlang or OTP is required.
