Deploying Elixir Applications: Releases, OTP, and Distillery

Deploying Elixir applications requires a solid understanding of how the Erlang VM manages code and state. Packaging your OTP applications into self-contained releases ensures reliable, repeatable deployments in production environments. This text-only course guides you through the core concepts of Elixir releases, focusing on Distillery and native release tools. You will learn how to configure, build, and deploy robust OTP applications that can perform seamless hot upgrades without service interruption. What you'll learn: - Understand the foundational architecture of OTP applications and the Erlang runtime system - Configure Distillery to package Elixir applications into self-contained production releases - Implement zero-downtime hot upgrades to update running code while preserving application state - Compare Distillery-based releases with modern native Elixir release configurations - Manage environment variables and runtime configuration securely in production - Troubleshoot deployment issues and monitor release performance on the Erlang VM The course begins with essential terminology and the basics of OTP application structure before moving into step-by-step configuration and release management. You will progress from local builds to advanced hot-upgrade scenarios and modern deployment best practices. This course is designed for beginner Elixir developers and system administrators looking to understand production deployments. No prior release management experience is required, though basic familiarity with Elixir syntax is helpful. Start mastering Elixir deployments and build highly resilient systems today.
