Mastering Elixir: Build and scale concurrent, distributed, and fault-tolerant applications

Leverage the power of Elixir programming language to solve practical problems associated with scalability, concurrency, fault tolerance, and high availability.

Key Features
Enhance your Elixir programming skills using its powerful tools and abstractions
Discover how to develop a full-fledged file server
Understand how to use Phoenix to create a web interface for your application.
Book Description
Running concurrent, fault-tolerant applications that scale is a very demanding responsibility. After learning the abstractions that Elixir gives us, developers are able to build such applications with inconceivable low effort. There is a big gap between playing around with Elixir and running it in production, serving live requests. This book will help you fll this gap by going into detail on several aspects of how Elixir works and showing concrete examples of how to apply the concepts learned to a fully fledged application. In this book, you will learn how to build a rock-solid application, beginning by using Mix to create a new project. Then you will learn how the use of Erlang's OTP, along with the Elixir abstractions that run on top of it (such as GenServer and GenStage), that allow you to build applications that are easy to parallelize and distribute. You will also master supervisors (and supervision trees), and comprehend how they are the basis for building fault-tolerant applications. Then you will use Phoenix to create a web interface for your application. Upon fnishing implementation, you will learn how to take your application to the cloud, using Kubernetes to automatically deploy, scale, and manage it. Last, but not least, you will keep your peace of mind by learning how to thoroughly test and then monitor your application.

What you will learn
Use Elixir tools, including IEx and Mix
Find out how an Elixir project is structured and how to create umbrella applications
Discover the power of supervision trees, the basis for fault-tolerance
Create a Domain-Specifc Language (DSL) that abstracts complexity
Create a blazing-fast web interface for your application with Phoenix
Set up an automatic deployment process for the cloud
Monitor your application and be warned if anything unexpected happens
Who this book is for
Mastering Elixir is for you if you have experience in Elixir programming and want to take it to the next level. This Elixir book shows you how to build, deploy, and maintain robust applications, allowing you to go from tinkering with Elixir on side projects to using it in a live environment. However, no prior knowledge of Elixir is required to enjoy the complex topics covered in the book.
