Elixir Production Management with run_erl and heart

Running Elixir applications in production requires robust monitoring and failover mechanisms to ensure continuous availability. Native tools like run_erl and heart provide lightweight, built-in solutions for system management and automatic node recovery without relying on heavy external dependencies. This text-based course guides you from the fundamental concepts of Erlang runtime management to configuring self-healing Elixir systems. You will learn how to handle application logs, interact with daemonized nodes, and configure automated heartbeat monitoring to automatically restart crashed nodes.\n\nWhat you'll learn:\n- Understand the core concepts of Erlang runtime supervision and daemon processes\n- Configure run_erl to redirect standard input and output for secure background execution\n- Implement heart to monitor node health and trigger automatic system restarts on failure\n- Manage and rotate production logs efficiently using native runtime capabilities\n- Integrate runtime tools with modern mix release deployments and systemd services\n- Troubleshoot common production failure scenarios through written practical exercises\n\nThe course begins with foundational definitions of the Erlang VM's management utilities before guiding you through configuration files and recovery scripts. You will practice managing real-world scenarios through detailed text-based scenarios and step-by-step code walkthroughs. This program is designed for backend developers and system administrators new to Elixir production management, with no advanced DevOps prerequisites required.
