Prerequisite Knowledge

This tutorial covers high level concepts about Erlang but is technical as well. Having some proficiency in at least one programming will be helpful, as well as some experience in building software systems.

Materials or downloads needed in advance

This tutorial does not require a full Erlang development environment, but if you'd like to experiment with the language it will be helpful to have a working copy of Erlang installed on your laptop.

You can download it from here: http://erlangcentral.org/downloads/


Erlang is a programming language designed for the internet age, although it predates the web. It is a language designed for multi-core computers, although it predates them too. It is the Ramones of the programming world, inspiring the sound and the beat which other mainstream languages are using. Erlang, more clearly than any other language, demonstrates the benefits of distributed, concurrency-oriented programming. In this tutorial, Francesco & Garrett will present the features that make Erlang a trendsetter and give you a context for using it as strategic tool in your software arsenal.

This tutorial will cover these topics:

Functional Programming in Erlang

  • Functions
  • Pattern matching
  • Recursion
  • Higher order functions

Concurrent Programming

  • Processes
  • Message passing
  • Links and monitors
  • Error handling



  • Basic principles
  • Riak Core
  • Scalable Distributed (SD) Erlang
  • Messaging Architecture


  • Behaviors
  • Releases and upgrades

Francesco Cesarini is the founder of Erlang Solutions Ltd. He has used Erlang on a daily basis since 1995, starting as an intern at Ericsson’s computer science laboratory, the birthplace of Erlang. Francesco moved on to Ericsson’s Erlang training and consulting arm, working on the first release of the OTP middleware, which he applied to turnkey solutions and flagship telecom applications. In 1999, soon after Erlang was released as open source, he founded Erlang Solutions. With offices in three countries, they have become the world leaders in Erlang-based support, consulting, training, certification, systems development, and conferences. Francesco has worked in major Erlang-based projects both within and outside Ericsson; and as technical director at Erlang Solutions has led the development and consulting teams. He is the co-author of Erlang Programming, recently published by O’Reilly. He lectures at Oxford University and the IT University of Gothenburg.
