The StratusLab collaboration provides an Infrastructure as a Service (IaaS) cloud distribution, allowing data centres to install private, community, or public clouds for their users. The distribution focuses on simplicity: allowing quick, straightforward installation on commodity hardware as well as easy access by scientists and engineers. Having run a cloud service based on StratusLab for several years, we will present issues that have arisen and provide examples of scientific use of the infrastructure. This will be followed by a live demonstration of the main features of the StratusLab cloud distribution.
