User Committee

As the number of production OpenStack deployments increase and more ecosystem partners add support for OpenStack clouds, it becomes increasingly important that the communities building services around OpenStack guide and influence the product evolution. The OpenStack User Committee mission is to:

If you are an OpenStack user, please take the OpenStack User Survey and join the mailing list to help the User Committee better define user requirements and serve the community. If you are interested in volunteering to help with User Committee efforts, please complete this form

The user committee is led by a core group three individuals, who provide oversight and guidance to a number of working groups that target specific areas for improvement.

Tim is currently responsible for the team at CERN which manages the operating system and infrastructure services. He previously worked as a Unix kernel developer at IBM and managing large scale Unix production deployments and services for Deutsche Bank. 

As part of CERN's project to add a second data centre, CERN is moving towards a large scale Infrastructure as a Service based on OpenStack aiming to support 15,000 hypervisors by 2015 to help analyse the 25PB of data a year from the Large Hadron Collider.

Jon Proulx

Job Title
Senior Technical Architect  

Most of my time is spent wrestling with Puppet configuration management and chasing the (nearly) latest version of OpenStack in one of the world premier computer science labs.

In the abstract I enjoy building large agile/adaptive systems and sharing knowledge with our users, my coworkers, and the free software community at large as both a learner and a teacher.
