This document summarizes lessons learned from scaling OpenStack technology. It discusses the transition from running Nova and Glance to adding additional components like Swift, Horizon, Quantum, Keystone, and others. It also covers lessons regarding security, UTF-8 encoding, primary keys versus VARCHARs, continuous integration, deployment challenges, documentation and testing, and the importance of an API. Overall it provides insights from an open source developer on scaling OpenStack and releasing new versions over time.
