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

## Things we studied in this chapter

In this chapter, we focused on legacy code. We spent most of our time working through tips and techniques for moving larger applications, but we also assessed Elixir dependencies.

The migration of any large application is a problem with both technology and people. Understanding the risk factors and getting buy-in from the beginning are critical elements. The application we move might be composed of independent services or a few monoliths. Moving a monolith means isolating different elements and moving them one section at a time.
