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

## Logger

The first defense against bugs is application-specific information, and the best way to acquire that is via old-fashioned logging. Elixir comes with the creatively named built-in Logger for logging messages. The word “messages” matters, because Logger was designed with a focus on text-based reports and not structured data. Logger contains four severity levels. From least to most severe, they are as follows:
