Multi-AKS Networking & Hub-Spoke Topology

Published on 2/25/26 6:30 pm by Jendrik Brack

Running more than one AKS cluster changes networking from a setup task into an operating model. This guide covers practical connectivity patterns, hub-spoke routing, cross-cluster DNS, ingress options, and decision criteria that help teams scale safely without adding complexity too early.

Cookie Banners Won’t Save You From ISO 27701

Published on 2/24/26 5:00 pm by Martin Stühmer

That boolean column you call “consent”? Regulators will laugh at it.

ISO 27701 demands granular, auditable, expiring consent, not cookie theater. Here’s the complete .NET implementation with Entity Framework Core, middleware validation, and Azure Functions that survives an audit.

NuGet Packages: Suppliers You Forgot to Audit

Published on 2/19/26 5:00 pm by Martin Stühmer

Every NuGet package is a supplier relationship under ISO 27001. Learn how to implement Central Package Management, automated vulnerability scanning, and package signature verification to transform your .NET dependency management from security liability into auditable compliance control.

Observability in AKS CNI Overlay: When Pod IPs Hide Behind Nodes

Published on 2/18/26 5:00 pm by Jendrik Brack

CNI Overlay masks pod IPs behind node IPs through SNAT, breaking traditional observability. Network logs show nodes, application logs show pods. Without Container Insights, correlation IDs, and distributed tracing, you’re debugging blind. SNAT port exhaustion mimics network failures, and timestamp-based correlation is fragile. The cost of proper monitoring is trivial compared to debugging outbound connectivity at 3 AM without visibility.

Your Azure SQL Is Public Right Now. ISO 27017 Demands You Fix It

Published on 2/17/26 5:00 pm by Martin Stühmer

That SQL Server you deployed last week? Publicly accessible. That Storage Account? Same story. Azure defaults are security theater. ISO 27017 calls this a compliance violation, and your next audit will too. Stop trusting “cloud-native” to mean “secure” and start implementing VNets, Private Endpoints, and NSGs before your data becomes someone else’s problem.
