This paper presents UnaCloud: an opportunistic cloud computing Infrastructure as a Service (IaaS) model implementation, which provides at lower cost than dedicated cloud infrastructures, basic computing resources (processing, storage and networking) to run arbitrary software, including operating systems and applications. The IaaS model is provided through the opportunistic use of idle computing resources available in a university campus. UnaCloud deals with the problems associated to use commodity, non-dedicated, distributed, and heterogeneous computing resources that are part of different administrative domains.
