At the Wikimedia Foundation (host of Wikipedia and many other open collaborative projects) we work on a limited budget, donated by our many generous donors. As many other companies that are not Facebook- or Google-sized, we have to do more with less both in terms of budget and our small number of Ops in order to serve the over 400 thousand requests per second and the 1200 million monthly users. We made several mistakes (and a few successes) along the road regarding architecture and hardware decisions, especially for the database-distributed components, storage model, hardware chosen, server size, technology adoption, etc. Now we want to share those with you.

He currently works for the non-profit organization Wikimedia Foundation. As a free software advocate, he tries to share what he has learnt in the past decade as a Linux Sysadmin and a MySQL DBA. He is specially interested on query optimization and distributed architectures for scaling and high availability.
