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 email the mailing list.

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

Matt Van Winkle


I serve an amazingly talented group responsible for running the Rackspace public cloud. I have been with the company in various roles for over 13 years.  My primary task is helping my teams of engineers and developers build the software that manages our constantly growing fleet of servers, enables easier day to day operations for our 24X7 Ops teams and facilitates smoother deployments by our software teams working on upstream OpenStack and other projects relative to our public cloud offering.

We have been growing our OpenStack based cloud since its launch in August, 2012.  It began in 3 regions with a few hundred hosts and is now in 6 separate geographic locations, has 10's of 1000's of hypervisors and contains well over 1 Petabyte of RAM under Nova management.  This cloud provides resources to an ever growing spectrum of users from all types industries, sectors and organizations.

Since late last year, I've had the pleasure of working with several in the community in elevating the voice and role of "Operators" within OpenStack.  I've helped with planning mini-summits, Ops meetup sessions in Atlanta and working closely with the Large Deployment team that met in Paris, Vancouver and beyond.

I began my OpenStack experience as a hobbyist and moved on to be an OpenStack Support Engineer with Rackspace, focused on succeeding technically while providing excellent service and support. Since initially engaging with OpenStack, I became extremely passionate about its success in every market across the globe. In just under three years I succeeded in creating an OpenStack Meetup in Houston, TX, becoming one of the leaders of the Ops Meetup Team, organizing Ops Midcycles, engaging with community operators, application developers, and end users as a member of the OpenStack User Committee, and OpenLab governance team member.

I currently work as Open Source Community Operations Manager for Huawei. I spend everyday working on how I can help OpenStack succeed in some small way.
