Abstract

InstantLab is our online experimentation platform that is used for hosting exercises and experiments for operating systems and software engineering courses at HPI. In this paper, we discuss challenges and solutions for scaling InstantLab to provide experiment infrastructure for thousands of users in MOOC scenarios. We present InstantLabs XCloud architecture - a combination of a privat cloud resources at HPI combined with public cloud infrastructures via ``cloudbursting''. This way, we can provide specialized experiments using VM co-location and heterogeneous compute devices (such as GPGPU) that are not possible on public cloud infrastructures. Additionally, we discuss challenges and solutions dealing with embedding of special hardware, providing experiment feedback and managing access control. We propose trust-based access control as a way to handle resource management in MOOC settings.
