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.

Adopting Elixir for Software Engineering Leads & Managers

Logger contains four severity levels. Which one is the most severe?

Logger contains four severity levels. Which one is the most severe?

While using your application in the production mode, what do we not need to rely on `Logger` for:



While using your application in the production mode, what do we not need to rely on <code>Logger</code> for:

**(True or False)** It is extremely important to never crash the Logger nor the Logger formatter because if that happens, you’ll get nothing to help you debug the problem.

(True or False) It is extremely important to never crash the Logger nor the Logger formatter because if that happens, you’ll get nothing to help you debug the problem.

**(True or False)** For SASL reports, it is not important to guarantee that the `:sasl` application is started before the `:logger` application.

(True or False) For SASL reports, it is not important to guarantee that the <code>:sasl</code> application is started before the <code>:logger</code> application.

**(True or False)** In debugging, using `:dbg.p :all, :all` will lead to an infinite loop.

(True or False) In debugging, using <code>:dbg.p :all, :all</code> will lead to an infinite loop.
