Newsletter 2022 week 16

25th April 2022

In this weekly newsletter, I write a summary of posts that got my attention during the week. I center around topics AWS, DevOps, Architecture, AWS CDK, Data Engineering, Data Analytics and much more.

If you like my content follow me on my usual spots to hang around:


Self-healing code with graceful degradation. Very cool idea that the solution keeps running with limited functionality even when a large portion of it doesn't work properly. There should be/are plenty of examples where Netflix or Amazon is doing stuff like that. The author even takes it a step further like having a read-replica database to keep serving HTTP GET reads but blocking writes when the main database is down and an HTTP GET write is requested. That approach sounds very promising in general and probably can be transferred to other similar situations as well.


Interesting content about Fuck-up-Stories in Companies and how healthy they can be when doing in a company. In the long term, it can increase the revenue of a company.

Jaeger QuickStart A post about Jaeger and how to run it in a QuickStart. Interesting as I didn't work much with Jaeger so much. It highlights how cool such Quick Starts are for starting quick :). Very interesting seems to be the fact that you can combine Jaeger with AWS X-Ray.

AWS Organizations and AWS SSO

A Reddit question for how to set up AWS Organizations and AWS SSO. I recommended giving a try.

VPN tunnel with AWS

VPN tunneling is already a tough topic at least for me. Cool instructions but I would prefer to have it as code somehow.

AWS Policy as Code

Policy as Code is getting more and more attraction. As an AWS CDK fanboy, I guess I do that for many years now ^^.

Very interesting post about what is a software architecture, software design patterns and abstractions.
