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.

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.

EU Data Act: The Beginning of the End for Cloud Monoculture?

What has the EU ever done for us? …well, aside from free movement, no roaming charges, consumer protection, the single market, Erasmus, and more. But also: excessive bureaucracy, slow decisions, overregulation down to the much-mocked bottle cap – a favorite symbol for anyone blaming Europe for every innovation shortfall.

Software Analytics going crAIzy!

I’ve long been an advocate of treating software like data and analyzing it accordingly with tools like Python, pandas, Jupyter Notebook, Neo4j, and jQAssistant. In the era of AI and code transformation tools, seeing software as data gets more and more important when you want to improve your software system at a large scale. This blog post is a short interim report from me about my efforts taking software analysis to the next level.

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?

Mobile Portale mit HATEOAS und Self-Contained Systems

Bei INNOQ setzen wir seit Jahren erfolgreich auf Self-Contained Systems und vertikalisierte Ansätze. Teams können unabhängig entwickeln, Services lassen sich separat deployen und skalieren - eigentlich ein perfektes Setup. Doch ein Problem blieb hartnäckig bestehen: Wie baut man Portale, die Daten aus verschiedenen SCS elegant zusammenführen?

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

From Data Graveyards to Knowledge Landscapes

Europe is sitting on a wealth of public data—but much of its potential remains untapped. The challenges are well known: fragmented portals, incompatible interfaces, and growing reliance on non-European platforms that slow innovation. While new industrial data spaces are emerging—enabling secure and sovereign exchange of sensitive information—public and industrial data ecosystems remain largely siloed. This article explores how Artificial Intelligence (AI) and the Model Context Protocol (MCP) can help bridge that gap and accelerate Europe’s shift from Open Data to Open Knowledge—supporting digital sovereignty and delivering greater value to society.

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.

Updating OWASP’s Microservice Security Cheat Sheet: Identity Propagation Patterns

Without trustworthy identity propagation, even strong initial authentication can be undermined — weakening trust boundaries and ultimately impairing the system’s ability to make reliable authorization decisions.

Business Model Canvas: Geschäftsmodelle sichtbar machen

Der Business Model Canvas hilft, zentrale Fragen frühzeitig zu klären: Wer sind unsere Kund:innen? Welches Problem lösen wir? Und wie erzeugen wir damit echten Mehrwert? Gerade an der Schnittstelle zwischen IT und Business schafft das Modell ein gemeinsames Verständnis – und hilft, technische Entscheidungen mit der Geschäftsperspektive zu verbinden.

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.

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.
