I'm Oliver.Cloud Architect& Specialist.
I think out loud about cloud architecture. About Landing Zones that hold thousands of accounts, security that convinces auditors, and running AWS cleanly at enterprise scale: what breaks, and how to prevent it.

What I write about.

AWS Certification: How to Get 30 Extra Minutes on Your Exam (DaZ +30)
AWS doesn't offer its certification exams in German, so native German speakers have to test in English. With \"DaZ +30\" you can request a one-time 30-minute extension to make up for that. Here's how to set it up.
AWS European Sovereign Cloud: What Six Months and One Live Test Actually Show
A reality check from a live account: what the sovereign AWS cloud can do today, where it hits its limits, and what that means for CIOs and CISOs in the DACH market.
What this site is about.
Multi-account architectures that scale.
Why governance and developer experience don't have to conflict, and how Control Tower makes both work.
Security architectures that convince auditors.
CIS benchmarks, ISO 27001, C5: thought of as code rather than PDF, and what that means in practice.
Platforms that launch fast and scale cleanly.
Lambda, Fargate, Step Functions, API Gateway: where the limits are and where they're not.
Cloud costs you understand and control.
Reserved Instances, Savings Plans, tagging discipline: why most teams fail at tagging.
