Statement of Interest

Large scale deployment of clouds to support scientific research


Tim is responsible for the group at CERN, the European Laboratory for Particle Physics, which manages the compute infrastructure for 13,000 physicists around the world to support fundamental research. He previously worked as a Unix kernel developer at IBM along with managing large scale Unix production deployments and services for Deutsche Bank in Europe.

His team is running the CERN OpenStack cloud which has been in production since July 2013 and is currently around 300,000 cores. This cloud provides processing power to analyse the data from the Large Hadron Collider and other experiments which produce around 100PB a year. The practical experiences are shared on the blog at .

Tim has been an elected individual director of the OpenStack management board since 2012 and was a founding member of the OpenStack user committee from 2013-2015.

Speaker Profile:


Tim is a candidate in the January 2021 Board Elections .


What is your relationship to the Open Infrastructure Foundation, and why is its success important to you? What would you say is your biggest contribution to Open Infrastructure Foundation's success to date?


During the past 8 years, I have been serving as a community elected member of the OpenStack management board and as a member of the OpenStack user committee for 3 years until September 2015.

CERN has been a regular contributor to OpenStack in many different forms, from code to operations meetups providing details of our deployment experiences and feedback to the community on improvements.

I have been a frequent speaker at OpenStack events, keynote talks at several summits but also at many of the country OpenStack days and local events.


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?


As a serving member of the board since its foundation, I have been involved in many of the details establishing the OpenStack project. As a production cloud operator, I have brought this view to the discussions and representing the needs of this vital part of the community.

My experience at CERN has been invaluable given the common principles of multicultural collaboration and meritocracy. As a publically funded organisation, CERN benefits from the same openness and transparency as one of its core principles with open source software being one of the ways we contribute back to society.



What do you see as the Board's role in Open Infrastructure Foundation's success?


The board provides the vital oversight of the foundation and business strategy with the individual directors providing the voice of the community in setting direction. Given a large board, it is key that there continues to be representation of those who are running OpenStack in production, understands the challenges of the user community and approprriate focus is placed on areas such as the collaboration with adjacent communities and interoperability to drive further adoption.


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


With the expanded scope of an open infrastructure foundation, there are opportunities for increased collaborations with other open source communities to enhance the integrations and reduce the effort for those operating and using these frameworks. 

Making the necessary governance and bylaws changes and establishing an expanded scope and membership model has already encouraged increased involvement and this can be further encouraged during 2021 while maintaining the spirit of the 4 opens which have served so well during the past decade.
