About the show

We are two brothers focusing 100% on Amazon Web Services (AWS). Every other week, one of us prepares the topic of the podcast. The topic is not known to the other one, which results in surprising conversations about all things AWS. Typically, we are covering the following topics: DevOps, Serverless, Container, Security, Infrastructure as Code, Container, Continuous Deployment, S3, EC2, RDS, VPC, IAM, VPC, and many more.

#096 AWS European Sovereign Cloud: Sovereignty or Just Marketing?

In this episode, Andreas introduces his long-time friend Thorsten Höger, with whom he shares a history going back to school and later working together on an AWS-powered online banking platform. Thorsten has spent over 10 years helping SMB customers in regulated industries build compliant AWS infrastructures, specializing in networking, security, Serverless, and CDK. He talks about his current consulting work and his upcoming product Deploymon. A major topic is the AWS European Sovereign Cloud (EUSC), where Andreas shares a field report and the hosts debate whether EUSC is genuine sovereignty or just "sovereign washing" given concerns around the US Cloud Act. They also discuss how small businesses can benefit from AI tools. Andreas uses AI to review blog posts, find bugs, and update dependencies, while Thorsten relies on it for customer offers, software development, planning, and research.
