Newsletter martinmueller.dev 2022 week 31

This week was my first week solely working as a freelancer. That is scary but exciting too :)!

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, Serverless, Data Engineering, Data Analytics and much more.

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

Aurora Serverless v2 PostgreSQL vs. provisioned Aurora PostgreSQL

https://towardsaws.com/aurora-serverless-v2-postgresql-vs-provisioned-aurora-postgresql-f60a93b99b83

That is an interesting article that compares the costs from Aurora Serverless v2 PostgreSQL vs Aurora PostgreSQL. And as you can read in the article it isn't always cheaper! Actually, it seems Aurora Serverless should be avoided when you have high DB traffic. So therefore perhaps use it for development and later consider switching to Aurora on-demand!

Thanks a lot to the author Ian Binder

CDK: Certificate Handling with Custom Resources

https://blog.56k.cloud/cdk-certificate-handling-with-custom-resources/

In this article, the author uses AWS CDK Custom Resources to solve a problem with DNS validating a certificate. As the custom domain isn't managed by Route 53 you can't use the standard route53 constructs to do that. Super smart how the author solved it by using a custom resource.

Thanks a lot to the author Jochen Zehnder

Containers vs Serverless

https://greengocloud.com/2018/10/07/Containers-vs-Serverless/

Super experiment article about containers vs serverless. It gives a short introduction to each and then the author gives his opinion. I agree with the author. If you want to know whom we are betting on then read the article!

Thanks a lot to the author Blake Green.
