BEAM There, Done That

Plangora

BEAM There, Done That is a podcast about building real systems with Elixir, Erlang, and the BEAM. We’ve built it before — distributed systems, fault‑tolerant services, event pipelines, real‑time apps, production nightmares, and the supervision trees that saved them. Each episode dives into practical lessons from shipping software on the BEAM: architecture decisions, scaling challenges, operational failures, and the patterns that actually work. No hype. No theory without scars. Just hard‑won experience from engineers who’ve been there.

    Phoenix’s Next Evolution: Chris McCord Unveils the DurableServer

    In this episode of BEAM There, Done That, hosts Francesco Cesarini and Allen Wyma sit down with Chris McCord, the creator of the Phoenix Framework, for a deep dive into the evolving world of Elixir, distributed systems, and durable processes on the BEAM. Fresh from ElixirConf EU, Chris shares the story behind his latest work on durable servers—a powerful abstraction that brings persistence, global process identity, and intelligent placement to familiar GenServer patterns. The conversation explores how these ideas emerged from real-world production challenges, including running geo-distributed applications across multiple regions with no single point of failure. Along the way, the trio unpack the current state of Phoenix and Phoenix LiveView, discuss why most new features are driven by production needs rather than theory, and debate hot topics like WebSockets vs. server-sent events, event-driven architectures vs. long-lived processes, and the true scalability limits of the BEAM. This episode is packed with practical insights for Elixir and Erlang developers building real systems: from supervision tree pitfalls and process design trade-offs to tracing, load balancing, and self-healing systems at scale. If you’ve ever wondered how to design applications that can survive crashes, move across nodes, and run globally with minimal complexity, this is a must-listen. Topics covered: Elixir, Erlang, Phoenix, Phoenix LiveView, distributed systems, durable objects, GenServer patterns, supervision trees, multi-region BEAM clusters, fault tolerance, and real-world production architecture.
