Digital Sovereignty: Why Architecture Matters and How to Make Your Company Resilient

In an era where digital systems form the backbone of our economy and society, control over one’s digital future is increasingly becoming the focus of strategic decisions. For many technology decision-makers in German-speaking regions, this is not just a political or regulatory challenge, but a fundamental task with far-reaching implications for software architecture work.

Data Inventories in the EU Data Act: The Democratization of IoT Devices

Starting in September 2025, the EU Data Act (Regulation (EU) 2023/2854) will require companies that collect or process data from connected devices to maintain comprehensive data inventories.

Digital Sovereignty as Self-Understanding

How implementation teams can escape the we-are-not-Google trap and collectively take responsibility for European solutions to European problems.

Think Locally: On-Premise LLMs as Drivers of Competitive Advantage

Consider this scenario: Your organisation has integrated AI tools into critical business processes, your legal team has carefully reviewed data processing agreements, and your IT department has configured systems to comply with GDPR requirements. Then, a foreign court issues an order that overrides all these protections, requiring your AI provider to indefinitely retain data that should be deleted—including potentially sensitive corporate information shared by your employees.

The Sovereignty Trap: Between Tiananmen and Trump

We talk a big game about values and privacy, yet depend on AI that either denies historical atrocities or could cut us off tomorrow. Is this what Europe gets for dropping the ball on high tech infrastructure?

Updating OWASP’s Microservice Security Cheat Sheet: Practical Considerations & Recommendations

Turning principles and patterns into practice — just as promised.

Updating OWASP’s Microservice Security Cheat Sheet: Decision Dimensions for Authorization Patterns

Choosing the right patterns is critical, as it directly impacts the system’s security posture, performance, scalability, and maintainability.

Updating OWASP’s Microservice Security Cheat Sheet: Authorization Patterns

Authorization patterns explain how distributed systems organize their access control — where and how decisions happen, where policies live — and influence, in turn, how identities and related attributes travel between components.

AI — Behind the Buzzword Garbage

Tired of AI hype? Me too. But beneath the buzzwords lies real value for developers. Tools like Claude Code save me hours on routine tasks, freeing me to focus on what matters: understanding problems and building the right solutions. It’s not magic—it’s practical support that makes development faster without replacing our core skills.

Without knowing who the subject is, without verifying its identity, there is only a limited way to perform meaningful access decisions.

What’s Wrong with the Current OWASP Microservice Security Cheat Sheet?

Modern microservice architectures require evolving security practices. Yet popular resources like the OWASP Microservice Security Cheat Sheet are starting to show their age and need a fresh look.

First Agile, Then Agentic

Agentic AI is supposed to accelerate software development. But new technologies can only reach their full potential when organizations adapt their structure, processes, and culture. Most organizations today are not yet able to truly benefit from faster software development. The prerequisite for this are the capabilities shaped by the agile and DevOps movements.

Technical and other Debt in IT Systems

This article explores the many hidden forms of technical debt that silently slow down IT teams—far beyond just messy code.

Common Approaches in the Field of Socio-Technical Architectures

In the age of digitalization and modernization, companies face the challenge of not only keeping up with technological advancements but also optimizing their organizational structures. Socio-technical architectures play a crucial role in this process by focusing on the flow of work, team collaboration, and the seamless integration of technical and social systems. This article explores two key approaches—Team Topologies and Domain-Driven Design (DDD)—and demonstrates how they can help organizations take the first steps toward consciously designing their socio-technical architecture.

Enabling Stakeholders as a Success Factor

Don’t Forget the People

On paper, the architecture vision is perfect. It addresses all pressing deficiencies of the existing system, aligns seamlessly with the business domain, and enables teams to retain more work within their boundaries. Finally, we will enjoy higher speed-to-market and a significant reduction in (non-value-adding, tedious) coordination efforts between teams. Surely, everyone will immediately see how much better our new architectural vision is. Not quite.

Internal Development Platforms

Internal Developer Platforms (IDPs) help us accelerate software development. They represent the natural evolution of developments over the past decades. We’d like to show why this is the case with a historical overview and then examine current challenges.

Socio-Technical Architectures: Informality from Mining to Today

Informal structures are hard to spot – but they can make or break a technical solution. Sociotechnical systems show why that matters, and what mining has to do with building apps.
