Edinburgh Napier University runs a custom cloud computing infrastructure for both student and public use. Such access carries dangers, both reputational and legal, as accidental or deliberate acts by users can be dangerous to other systems. This paper considers the experience gained in running this system, and offers techniques to help mitigate the dangers, and maintain high availability, while still providing a useful platform for educational purposes.
