can people give real world business use cases for where they are using elixir? What industries are you working in? what actually gets done in the real world at the end of the day with the system you're working on? e.g. are more ads served to web users? are you monitoring methane on IOT things strapped to cows in farm fields?
PagerDuty has standardized on Elixir as the backend language of choice after a couple of years of incremental adoption with new services. Developer happiness definitely helped get the word spread. https://www.pagerduty.com/blog/elixir-at-pagerduty/
Additionally, I believe Riot Games uses Erlang for their in-game chat and maybe other services. Also DemonWare (part of Activision Blizzard) used Erlang for CoD Black Ops, presentation here: http://www.erlang-factory.com/upload/presentations/395/Erlan...
Anywhere where Erlang is used, Elixir can be used too :)
www.lovethework.com run on elixir. Data transfer and transformation from an old system, web frontend (we are refactoring a lot of the current javascript stuff recently), ecommerce, the admin stuff on the back office too.
