Interviews with decision-makers, turned into my own articles
I develop the questions myself, conduct the conversations myself and turn them into independent specialist articles for the German and international trade press. Companies supply no finished material. The choice of questions and the assessment stay journalistic.
Product and AI strategy at Google Cloud and the agentic enterprise platform.
Digital sovereignty and a sovereign cloud for the DACH region.
Cloud security, exposure management and securing AI-generated code.
Continuous Threat Exposure Management and Attack Surface Management in the cloud.
The sovereign European cloud from the provider's perspective.
The analyst's view of the European cloud market and digital sovereignty.
Google Cloud Summit DACH 2026, Frankfurt
On site at the press roundtable „Agentic Enterprise in DACH". The conversations and sessions turned into a series of articles, among them the Gemini Enterprise Agent Platform, the collaboration of AI agents via A2A, ADK and MCP, and the AI Agent Marketplace.
Further conversations took place with Rolf Schumann (Schwarz Digits) and Markus Schuster (Procilon). Digital sovereignty runs both ways. InCyber News interviewed me as an expert on the European cloud market.
Voices from editors and readers
„The book "Windows Server 2022" is one of the most comprehensive Windows Server books on the market. Thomas Joos, a leading authority in this field, delivers another instructive and informative title that can be used as a reference work by beginners as well as experienced Windows Server administrators."
„Quite simply THE PERFECT book on its subject. Not a word too many, not one too few. I work in IT professionally, and the current edition of this book has been on my shelf for years. In my opinion, THE STANDARD REFERENCE on this topic."
„I am happy to pass on the feedback from One Identity PR, the senior marketing manager and above all the EMEA Field Marketing team, which uses the publications Europe-wide. Everyone is thrilled with the contributions, especially the latest strategic article that just appeared on Security-Insider."
„The approval for your specialist article for our client Kontron has now reached us. Many thanks for the pleasant collaboration! We look forward to the next article assignment with you."
„You produced excellent practice-oriented articles for us on Kontron in the retail sector, as Jan Lauer reported to me – pieces that were even partly placed via you."
„The Kontron piece is exactly the right format for us."
„Many thanks for the great interview last week! We are delighted that you will turn it into an interview piece."

„I always read your iX articles with great benefit – the Proxmox pieces have stuck with me in particular."
„I read the Security-Insider news regularly. The Patch-Tuesday summary is informative, alarming and reassuring at the same time. The information is correct and important, and the summary is simply brilliant."
„Thank you so much for the help in resetting my PC after that destructive update. Games no longer worked at all. Not a single one! Now it works again and I am extremely happy."
„Compliments on your tips, highly recommended!"
„Looks great."
