Architecting Real-Time Applications with Elixir and Phoenix

Building highly concurrent, real-time web applications requires moving from basic product requirements to a solid technical plan before writing a single line of code. This text-only course guides you through the entire architectural process of planning a real-time, high-concurrency e-commerce application using Elixir and the Phoenix framework. You will learn to: 1. Understand core Elixir concurrency patterns, OTP behaviors, and real-time state management. 2. Translate business and product requirements into technical specifications and database schemas. 3. Design real-time communication flows using Phoenix Channels and Phoenix PubSub. 4. Map out high-concurrency strategies to handle sudden traffic spikes and live stock updates. 5. Apply modern Phoenix LiveView architectural patterns for seamless state synchronization. 6. Configure basic telemetry and application monitoring strategies for production readiness. You will start by exploring foundational real-time terminology and the Elixir actor model. From there, you will walk step-by-step through designing a simulated real-time sneaker store, learning how to structure processes, manage state, and plan for massive concurrency. This course is designed for beginner-to-intermediate developers who understand basic programming concepts and want to learn how to architect real-time systems. No advanced systems design experience is required. Start reading today to master the art of planning scalable, real-time applications with Elixir and Phoenix.
