Statement of Interest

Using OpenStack in a service provider environment, doing enterprise-class operations


I started my careen in 1997 at IBM Germany, when I came across a new open-source operating system called Linux which drew a lot of my attention and continued to do so until present time. Over the time the scope grew larger, and I followed the open-source path to the cloud world and got part of the OpenStack (back then) and now OpenInfra family. 

Since 2012 I'm with T-Systems in different leadership roles and in 2014 we started a project to launch a public cloud for T-Systems/ Deutsche Telekom. This was the start of Open Telekom Cloud (OTC)! 

As the infrastructure lead and chief engineer, I am responsible for everything between the upper edge of double floor in the data center and the upper edge of the operating system. Open Telekom Cloud is by now one of the largest OpenStack-based clouds in Europe, providing full GDPR-compliance and the full stack of IaaS, PaaS and SaaS offerings.

Apart from doing all that computer stuff, I am married, have a son, and enjoy a lot doing some cooking & baking, spending time with my family and travelling throughout the world.


I'm involved in the following OpenStack projects: Nova,Swift,Glance,Heat,Openstack-ci,Deployment,Release

What is your relationship to OpenStack Foundation (OSF), and why is its success important to you? What would you say is your biggest contribution to the OSF and the success of its projects to date?


OpenStack and OpenInfra is the foundation for my professional career. I was always attracted by open-source operating systems and infrastructure. Going large-scale, OpenStack was the next logical step. Watching it grow and being part of that journey is just amazing.

For us at T-Systems OpenStack was the perfect fit when we evaluated how to deploy a public cloud for Deutsche Telekom and T-Systems back in 2014. Ever since then we worked closely with community and vendors to make it "service provider ready", even one step further than just "enterprise ready". 

Today we proudly run one of the biggest OpenStack-based clouds in Europe.


Describe your experience with other non-profits or serving as a board member. How does your experience prepare you for the role of a board member?


I worked very close with my former manager, Clemens Hardewig, who held the board position for T-Systems since we became Gold Member of the Foundation. With his experience  in the back I see myself well-prepared for the role as board member.


What do you see as the Board's role in OpenStack's success?


The board should give direction for the next years of strategy of the OpenInfra foundation. 


What do you think the top priority of the Board should be over the next year?


Secure the importance of OpenStack in the cloud market and broaden the footprint in the surrounding environment with the OpenInfra Initiatives.
