2. AGENDA • Elixir • Phoenix • Conclusion
3. AGENDA • Elixir • Phoenix • Conclusion
5. PLATFORM FEATURES - BEAM • Scalability & Concurrency
 |> Processes (isolated lightweight threads) • Fault-tolerance
 |> Let-it-crash & supervisors • Distribution
6. LANGUAGE FEATURES • Functional Programming • Pattern match • Immutable • Extensibility and DSLs • Ruby-like syntax
7. PROS AND CONS • Concurrency • Immutability • Modern syntax 1304 $0/4 • Hard to learn • Unstable language specifications • Few developers (especially in Japan)
8. Sample Code
9. PIPELINE OPERATOR
10. PATTERN MATCH (FizzBuzz) http://qiita.com/rei-m/items/261f39cd438f801eeb1c
11. HELLO WORLD! (Message passing)
12. AGENDA • Elixir • Phoenix • Conclusion
15. FEATURES • High performance • High productivity (like RoR) • Stability and Scalability
16. HIGH PERFORMANCE
17. BENCHMARKING Phoenix showed 10.63x more throughput over Rails when performing the same task, with a fraction of CPU load SEE: http://www.littlelines.com/blog/2014/07/08/elixir-vs-ruby-showdown-phoenix-vs-rails/
18. PROS AND CONS • High Productivity • High Performance • High Reliability • Easy to learn 1304 $0/4 • Few Library, Plugin, Developers • PaaS: Heroku only (?)
19. AGENDA • Elixir • Phoenix • Conclusion
20. CONCLUSION • Learn BEAM lang • Learn you a elixir for great good • Adopt Phoenix instead of Rails
