Mastering Distributed Systems with Elixir

Mastering Distributed Systems with Elixir: From OTP Foundations to Clustering, Scaling and Deployment is the definitive guide for developers who want to build reliable, fault-tolerant, and scalable applications on the BEAM virtual machine. Whether you are new to Elixir or already using it in production, this book equips you with the practical knowledge to design, deploy, and operate distributed systems with confidence.

You'll start with the fundamentals of OTP, learning how processes, supervisors, and GenServers form the backbone of resilient applications. From there, you'll explore advanced topics such as clustering nodes, handling failures gracefully, and managing distributed state with tools like ETS and Mnesia. Real-world chapters cover event-driven architectures with GenStage and Broadway, service discovery with Phoenix.PubSub and libcluster, and strategies for distributed task management with Horde.

Deployment is treated as a first-class concern. You'll learn how to package releases with Mix, containerize with Docker, and run applications at scale on Kubernetes and modern cloud platforms. The book also covers observability structured logging, metrics collection, and tracing with OpenTelemetry so you can monitor and debug production systems effectively.

By the end, you'll have the skills to design event-sourced systems, build fault-tolerant job queues, and scale applications across multiple nodes and regions all while maintaining the reliability and performance Elixir is known for.

Key topics include:

• OTP processes, supervisors, and fault tolerance
• Distributed naming, discovery, and service coordination
• Event-driven pipelines with GenStage and Broadway
• CRDTs, CQRS, and event sourcing patterns in Elixir
• Deployment with Mix releases, Docker, and Kubernetes
• Observability with Telemetry, metrics, and OpenTelemetry
• Scaling, load balancing, and multi-region architectures

If you want to move beyond single-node applications and harness the full power of Elixir for distributed computing, this book is your roadmap.
