Sascha Wolf goes over building an internal tool with Phoenix and Elixir. It's hosted on AWS in a Kubernetes cluster through EKS.
In this episode of Running in Production, Sascha Wolf walks us through an
internal tool he built to help deal with microservices. It’s written in
Phoenix and Elixir and is hosted within a Kubernetes cluster on AWS using EKS.
It’s been running in production since mid 2019.
Sascha talks about rewriting the prototype from Java to Elixir, taking
advantage of Phoenix Channels, creating event driven systems, moving from
Heroku to AWS and really making the most of OTP features such as using stateful
processes.
Topics Include
4:26 – Motivation to rewrite the prototype from Java to Phoenix and Elixir
6:45 – Live View likely would have been used if it were around when they started
9:17 – 30+ microservices in 1 git repo and deployment isn’t really a pain
12:46 – This Stacker service is pretty big with about 90 Elixir modules
18:06 – On the front-end it’s just a little bit of vanilla Javascript
21:44 – Useful libraries in their mix.exs file
23:59 – Most of the other services are written in Ruby (for now)
25:25 – Running on Heroku, but moving to AWS with Docker and Kubernetes with EKS
28:32 – Terraform is used to manage their infrastructure as code with Circle CI
32:09 – Load balancers, AWS API Gateway and using Lambda for backups
34:09 – Sentry for error reporting and an ELK stack for viewing logs
34:55 – Deploying code from development to running live on the Kubernetes cluster
40:36 – Backups are handled by Amazon’s managed services
42:59 – Best tips? Don’t be afraid to jump into OTP and leverage process state
45:31 – Sascha is on Twitter, he has a personal site and Better Doc is hiring

Support the Show
This episode does not have a sponsor and this podcast is a labor of love. If
you want to support the show, the best way to do it is to purchase one of my
courses or suggest one to a friend.
Dive into Docker is a video course that takes you from not knowing what Docker is
to being able to confidently use Docker and Docker Compose for your own apps.
Long gone are the days of "but it works on my machine!". A bunch of follow
along labs are included.
Build a SAAS App with Flask is a video course where we build a real
world SAAS app that accepts payments, has a custom admin, includes high test
coverage and goes over how to implement and apply 50+ common web app features.
There's over 20+ hours of video.
