How Elixir Came to Spotify with Joel Kemp

We talk with Joel Kemp about his experience introducing Elixir at Spotify. We learn about the concurrency problems he had with the default stack and how that was solved with the BEAM. We talk about the inertia that larger companies have that make introducing any change harder. Joel compares the process to running a marathon and shares some tactics used to help build internal support and interest. Fascinating insight into a well known company and how Elixir is helping internally.
