I have been using Erlang since 2008, and started using Elixir in 2014. I much prefer the Elixir syntax. It files off the rough parts of the Erlang syntax, e.g. needing to keep track of commas, periods and semicolons at the ends of lines. The most important thing Elixir adds, though, is lisp-style macros, which makes everything else easier. This is the post which made me switch to Elixir: https://littlelines.com/blog/2014/07/08/elixir-vs-ruby-showdown-phoeni… We get the best of both worlds: the ease of use of Rails with the power of Erlang.

In case you are wonder why the excitement about Exilir ... Exilir allows you to easily create DSL in Erlang. Phoenix is a great example that has used Exilir to create a DSL that is similar to Ruby on Rails. http://www.littlelines.com/blog/2014/07/08/elixir-vs-ruby-showdown-pho…

Granted this is speculation, but I've done my homework: 1) Extreme concurrency due to Erlang underneath, which means not only being able to handle lots of connections at once, but very good DDoS resistance. See WhatsApp's blog post about it: http://blog.whatsapp.com/196/1-million-is-so-2011 An Elixir (or Erlang) process can fire up a million new nodes in a second on commodity hardware. No joke. The out-of-the-box concurrency in Elixir replaces many tools in Ruby that are normally separate gems: http://www.smashcompany.com/technology/ruby-concurrency-needs-microser… 2) Near-100% uptime possible. (Google "Whatsapp uptime"). Erlang was designed to run cell networks. It made them very reliable. The entire philosophy of the language is to "embrace failure, log it and try again ASAP." This ends up being a very good strategy when dealing with the uncertainty of the real world, and things like security concerns. 3) Live code upgrades without downtime. See this demo: https://youtu.be/96UzSHyp0F8 4) MUCH nicer syntax than Erlang. Especially for ex-Rubyists. It's a functional language (with all the advantages that provides) with a Ruby-flavored syntax. Best of all worlds. 5) Phoenix, the Rails-equivalent web API, has come out of the gate with a 2 to 10x performance improvement over Rails using a fraction of the CPU load: http://www.littlelines.com/blog/2014/07/08/elixir-vs-ruby-showdown-pho… 6) Elixir provides true macros (in the Lisp sense). It…

Except Phoenix and Elixir are just faster out of the gate than Rails and Ruby! "tl;dr Phoenix showed 10.63x more throughput over Rails when performing the same task, with a fraction of CPU load" https://littlelines.com/blog/2014/07/08/elixir-vs-ruby-showdown-phoeni… You can tack on a Phoenix app on top of a Rails app's database and immediately get big improvements as Rails can be a bottleneck.

1GB is an obscene amount of ram for a webapp, it's just that Ruby is a memory hog. You can run an Elixir webapp with much much less memory. See: http://www.littlelines.com/blog/2014/07/08/elixir-vs-ruby-showdown-pho… tl:dr; Ruby/Rails: 235.37MB Elixir/Phoenix: 34.69MB
