The future is now. Moore's law finally made computing multi-core. Internet connection form a sign of wealth or affiliation with academia became a human right. Humanity routes massive amounts of data every second and a certain portion of this data hits services we develop and maintain.

Today it's extremely important to be able scale up and scale down dynamically and painlessly. Imperative approach fails to deliver a set of tools required to write scalable systems effectively, so the solution to this problem we'll examine during this workshop is in the domain of functional programming. Even though simply using a functional programming language mitigates a lot of issues with writing concurrent code from imperative approach, it would be handy to have a concurrency model supported by a concurrency framework.

In our workshop we will observe an application of Erlang's concurrency model by using Elixir programming language to build a blog engine.

• 10 minutes — problems of Erlang
• 20 minutes — introduction to Elixir

• 1 hour — work with posts (*)
• 1 hour — work with commentaries (*)

(*) breaks are possible whenever an attendee needs one"
