We talk with Brooklyn Zelenka from SPADE Co. about their current and past Elixir projects and how they are deployed. Brooklyn Zelenka - SPADE Co. Find Brooklyn elsewhere online: https://twitter.com/expede https://github.com/expede 1:08 - Brooklyn’s Background Brooklyn's background and experience with Elixir is deep. Huge open source contributor. Got started in Elixir just after Phoenix got to 1.0. 1:53 - Worked on several Elixir projects in production. 2:43 - Why she got into Elixir. Real Time More performant than Rails. Great documentation Industrial-grade 4:38 - When you wouldn't use Elixir. Easy to get stakeholder buy-in. Just point to WhatsApp. Elixir is made for 2019 CLI tools Repl-driven development TDD tools built in by default All the best practices we have today are built in. 7:14 - Where has Brooklyn hosted her apps? Heroku for POC's. AWS for production. Dockerized because "kubernetes is the new hotness" 9:40 - Do you do any clustering? Load balanced above. AWS load balancing is very standard. They're well understood and have a nice developer experience. 10:29 Are you able to get any zero downtime deploys? Zero downtime deploys. Awesome but impractical. Rolling deploys are easier and usually more appropriate. Some requirements make it valuable. Erlang error states. Exceptional. Allows you to build for the happy path. Don't worry about error handling all the time. Witchcraft and dark magic. Monads. Poke around the standard library. 12:50 - How does Elixir compare to Rails in terms of response times, and other aspects? 15:32 - What libraries do you use and what have you built? 22:41 - Any cool features of OTP you are using? 25:36 - One tip to developers new to Elixir Build up a peer-to-peer cli chat from scratch in one GenServer.

We talk with developers from the team here at SmartLogic about our current practices on deploying Elixir and Phoenix in production. Dan Ivovich - Director of Development Operations @ SmartLogic Learn more about how SmartLogic uses Phoenix and Elixir. 00:00 - Fade In 00:30 - Introductions to Eric, Dan and SmartLogic Dan Ivovich - Director of Development Operations @ SmartLogic Eric Oestrich - Developer, Elixir Lead @ SmartLogic Justus Eapen - Full stack developer @ SmartLogic Introduced to Elixir by an old colleague. 1:20 - What Elixir projects do you have in production? Several client projects in production. Several Mobile Apps with APIs powered by Phoenix and Elixir. Baltimore Water Taxi. A digital marketplace. And more! 1:57 - Advantages and disadvantages to using Elixir. We made the switch when a colleague was stoked about Functional Programming and introduced us to Elixir. We were won over by the performance and rich feature sets, OTP, etc. 2:43 - Where are we hosting our Elixir Apps? Heroku AWS Linode Digital Ocean 6:20Deployment process, tools, scripting Ansible - for underlying VPS’s, servers, and more recently deployment itself. (Similar to Capistrano). Distillery Mix.release 7:18 - Zero Downtime Deployments Old school load balancers and rolling restarts 7:46 - What are the performance metrics like? Comparatively. Ruby ends up with memory leaks. That doesn’t happen with Elixir. Memory utilization is flat and low no matter what. “Phenomenal response times” 8:54 - How does Eric think about clustered applications in Elixir? Going Multi Node (https://www.youtube.com/watch?v=lCUKQnkjajo) Pg2 - process groups Mnesia distributed database (beware!) “Just sending messages to pids because Erlang is great” Swarm / Horde 12:40 - How do we handle background tasks? Started with verk Recently becoming more comfortable with spinning up GenServers “The language itself is built to be concurrent.” 15:06 What libraries are we using in prod? First thing: You don’t need a whole lot because the language is so well designed. Phoenix - web framework Ecto - sort of an ORM Distillery - for releases Bamboo - for sending emails Quantum - for task scheduling Timex - for dates and times, and timezones Cachex - for caching 18:20- What third party integrations have we attempted Stripe Square Twilio Mindbody Always building our own clients.  Using HTTPoison 19:58Has Elixir ever saved the day in production? It’s saved many days by PREVENTING ISSUES. Systems are architected for reliability and fault-tolerance. 21:48 - Where do supervision trees come from? What is OTP? OTP is an Erlang standard lib Includes supervision trees, genservers, ETS, and a lot of stuff we don’t even know about! gen_tcp Mnesia dets 23:43- Tips for devs considering running elixir in production. Jump in and read the docs Understand how systems boot, distillery releases, config providers, etc. “Good server monitoring hygiene” “DIVE IN!” 19:54 Outro Learn more about how SmartLogic uses Phoenix and Elixir.Special Guest: Dan Ivovich.Links:Going Multi-NodePG2mnesiaSwarmHordeVerkBambooQuantumCachex
