Exploring OTP and Key Concepts for Effective Application Development in Elixir

Alvaro Callero's talk at ElixirConf US 2024 dives into the core concepts that are essential for leveraging Elixir's capabilities in application development. It begins with an explanation of Elixir processes, highlighting how they are lightweight compared to operating system processes and how they facilitate concurrency and fault tolerance. The presentation then transitions to Behaviours, discussing their role in defining function sets for modules and ensuring code consistency. Next, the Agent module is introduced as a simple way to manage state, along with strategies for its effective use in shared data management. The Task module is also covered, showing how it enables asynchronous task management to improve application performance. Finally, the discussion wraps up with an in-depth look at GenServers, a critical building block for managing state and handling concurrent requests, supported by real-world examples demonstrating their significance in building resilient systems.
