Elixir is a relatively new framework but shows rapid growth due to its flexibility as a functional, concurrent, distributed programming language.

This course is a practical guide to adopting an Elixir-based technology stack for distributed web applications. Engineering managers will find helpful guides on upskilling and cross-skilling their teams, and technical leads will grasp the meaningful differences between Elixir and traditional stacks. The course moves from high-level concepts such as staffing, code management, and legacy systems to developing your Elixir environment with a walkthrough of making the functional transition, distributed Elixir, and integrating external code. You’ll wrap up with deployment and maintenance functions, assessing performance, and finalizing the application.

By the end of this course, engineering managers will be prepared to tackle the unique challenge of migrating web applications to Elixir.

Adopting Elixir for Software Engineering Leads & Managers

## What are NIFs?

**Native implemented functions**, or **NIFs**, allow developers to load external code into the same memory address space as the Erlang VM. Our code can integrate quite closely with functions implemented in other languages. While such tight integration may seem appealing because of the obvious performance benefits, we need to be careful. This power comes at a price. NIFs may be clean, but they do not necessarily share the same founding principles we do in ElixirLand. We must think of NIFs as unsafe. This is because of the following reasons:
