Optimizing BEAM Resource Management for Real-Time Applications

To build truly resilient, low-latency systems, you must understand how your runtime environment handles resources under heavy load. The BEAM virtual machine excels at concurrency, but maximizing its potential requires a solid grasp of its internal CPU and memory management. This text-based course guides you through the foundational mechanics of the BEAM, enabling you to write highly optimized Erlang or Elixir applications. You will discover how to prevent bottlenecks, manage process mailboxes, and configure the runtime for predictable, real-time performance. What you'll learn: - Understand the fundamental architecture of the BEAM virtual machine and its process model. - Manage CPU utilization using schedulers, dirty schedulers, and work-stealing algorithms. - Configure memory allocation, garbage collection, and process heap sizes to prevent latency spikes. - Identify and resolve common bottlenecks such as message queue buildup and selective receive issues. - Apply modern observability patterns using Telemetry to monitor system health in real time. The journey starts with foundational definitions of BEAM processes and scheduling, before moving into practical memory management strategies and performance tuning techniques. Through clear written explanations and illustrative code snippets, you will learn how to diagnose and resolve real-world resource constraints. This course is designed for developers new to BEAM internals, requiring only a basic familiarity with Elixir or Erlang programming.
