OTP for Elixir Programmers

So you've built and deployed a Phoenix application backed by Ecto and Postgres, and come to the conclusion that you love it. If you are looking at progressing to the next level, this hands-on training is for you. It will help you understand what happens behind the scenes when building applications using OTP behaviours. Learn about the battle-tested abstractions needed to build back-end, fault-tolerant systems that will run for years and scale to billions of users. We'll have plenty of time to work on labs along the way as you hone your skills and put the theory into practice. About half of the class is either lab work or coding side-by-side with your instructor.

EXPERTISE

  • Intermediate

 

COURSE DURATION

  • 5 days

 

TARGET AUDIENCE

  • Software Developers, Engineers and Architects

 

PREREQUISITES

  • Basic knowledge of sequential and concurrent Elixir

 

OBJECTIVES

  • Have a deeper understanding of how to architect back-end systems and micro-services that you can access and use from Phoenix.
  • Learn why we need behaviours such as Generic Servers, Generic State Machines and others, when to use them, and how to integrate them into supervision trees.
  • Get the knowledge about how to deal with load issues applying some techniques like pooling, circuit breakers or producer/consumer solutions.
  • Get a deeper understanding about how an Application works and how to create them and work together with others.

 

COVERS THE FOLLOWING TOPICS

  • ETS (a Redis in your beam)
  • Behaviours
  • Supervision
  • Generic Servers
  • Generic State Machines
  • GenStage
  • Applications (and the use of Observer)
  • System Principles & Release Handling
  • Release Handling

 

WHY YOU SHOULD ATTEND THIS COURSE

  • Helps you get over the hurdle of learning how to build systems with OTP
  • Allows you to avoid the pitfalls and borderline cases handled in its libraries
  • A cost effective approach to increasing productivity whilst reducing mistakes
  • Allows you to design and develop systems using the globally recognised Erlang approach

Typeclasses: the value of programming vocabulary

Monoids, Applicatives, Monads and Semigroups. What are these things?

Much more importantly, however, why should one care?

Elixir programmers are blessed with a language that allows them to be productive, seemingly without needing to reach for these arcane spells. And yet, for building architectures we have spells like "GenServer" and "Supervisor", among others.

Maybe we can find useful tools in the ivory tower of Haskell?

OBJECTIVES

  • Introduce the concept of typeclasses to the uninitiated.
  • Inspire a sense of marvel over the kaleidoscope of ways to categorize things. 
  • Lead the audience to a library that lets them explore typeclasses in Elixir (https://github.com/expede/witchcraft).
  • Inspire the audience to seek out the words that are useful for describing their everyday work.

AUDIENCE

Programmers primarily experienced in dynamically typed languages, who are curious about the alleged benefits of the contraptions that they make up in the ivory tower of Haskell.
