The future of the Erlang ecosystem, in the home of Erlang!

Code BEAM STO conference is all about discovering the future of the Erlang Ecosystem and bringing together developers as a community to share knowledge & ideas, learn from each other and inspire to invent the future.


An action-packed two-day conference fused with a mix of talks on innovation and open-source applications based on Erlang, OTP, Elixir, LFE, BEAM and other emerging technologies!

We're working behind the scenes to build Code BEAM STO 2019!


Introduction to Erlang and Elixir

New to Erlang and/or Elixir? Interested, but don't know quite where to dig in? We've all been there! In this track, you will learn from other's experience, get a sense of the lay of the software ecosystem, get help from the community and contribute back for everyone's benefit.


Erlang and Elixir's popularity is growing but it's not always clear what off-the-shelf software is useful in production quality systems. In this track you will learn what existing production systems' maintainers are using to monitor and test their systems. This track will include the war stories and experience reports of novice and expert users alike.


Every new domain that Erlang and Elixir push into brings a new class of problems and a new class of solutions. In this track, we'll learn from other's experience, where things have been peachy and where they haven't been so much. We'll all walk away with a more clear idea of how to build highly reliable software.


Learn from the leading experts and Erlang committers about new language constructs, VM implementations, and powerful libraries which form the Erlang eco-system. You will learn how many of its features work and how to best use them to write fast and efficient code.


In this track, you will learn from the leading experts and committers about new and leading frameworks such as (but not limited to) Phoenix, MongooseIM, Nerves and RabbitMQ. You will find out how these frameworks work, how to best use them and where not to use them.

Distribution, concurrency, multicore, & functional

Scaling vertically by adding more powerful hardware is a thing of the past. We scaled horizontally, by adding more commodity hardware. With mega-core architectures, we have the choice of adding more hardware, more cores, or both. Erlang style concurrency puts us ahead of the game when it comes to scaling with both approaches.
