This document summarizes a presentation by Raymond Siebert about 1&1's use of MySQL. It discusses 1&1's history and growth as an internet service provider. It describes 1&1's shift to open source solutions like Linux, Apache, PHP, and MySQL due to cost efficiency and flexibility. 1&1 operates around 700 internal MySQL installations for customer products, ordering processes, billing, and more. These installations utilize high availability configurations and geo-redundancy. MySQL has helped 1&1 scale to support its fast growth while maintaining availability, though the presenter notes MySQL has limitations for big data and business intelligence workloads.
