In this episode of Running in Production, Dan Kolbman goes over using Django to build an internal tool that helps make sense of ~5 Petabytes of Genomic data that is then made available to clinicians. It’s running across many different AWS resources using ECS Fargate.

Dan walks us through what their app does, dealing with loads of data, using GraphQL, getting away from using Serverless and going mostly all-in with AWS. Their apps are open source too. The ones we’ll be talking about are on GitHub here and here.

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.
