Hi I'm Trond. I work on microservices, Kubernetes, cloud stuff and python. This is a blog about that.

AWS Multi-Account setup: It's complicated

I think it's about 5 years since I started using AWS "for realz". We were gearing up to migrate a bunch of stuff from on-prem to cloud and we planned to use Azure - we were a Windows/.net shop after all. But. There were some issues. So just for fun, we took an app that we were having serious difficulties running in Azure, and refactored it to run on AWS Lambda using Kinesis Firehose and S3 (it was a kind of event ingestion app), and it was rock solid from day one (as far as I know, it still hasn't missed a beat). As we learnt about the mature client sdks in all languages we neeeded, complete documentation and robust (and actually understandable) vpc networking, it just clicked. We did a 180, scrapped Azure and went full steam ahead on AWS. And we mostly never looked back.

Testing in production aka user-based dynamic api routing

We've been discussing testing in production for a long time. Especially for our "main" api we knew we needed to do something in order to improve the way we develop and deploy. This api relies on production (or production-like) data, and is also the primary contact point for a host of different clients (both apps, set-top boxes and web apps).

Migrating to Traefik 2.0 without downtime

We've been using Traefik as the Ingress Controller of choice ever since we started using Kubernetes. We also use Traefik for our non-containerized apps, where Consul is used as the "source of truth" for routing configuration.
