Buckle up your shoes and prepare to tackle the unique challenge of migrating web applications to Elixir.

Become an Elixir Professional

Elixir is a relatively new framework but has shown rapid growth due to its flexibility as a functional, concurrent, distributed programming language. In this module, we'll learn about adopting an Elixir-based technology stack for distributed web applications. Then, we'll learn high-level concepts such as staffing, code management, and legacy systems. We’ll also learn to develop our Elixir environment with a walkthrough of making a functional transition, distributing Elixir, and integrating external code. We'll wrap up the module by looking at deployment and maintenance functions, assessing performance, and finalizing the application.
