Software Defined Networking (SDN) is rapidly transforming the networking ecosystem of cloud computing data centers. However, replicating SDN-enabled cloud infrastructures to conduct practical research in this domain requires a great deal of effort and capital expenditure. In this paper, we present the CLOUDS-Pi platform, a small-scale cloud data center for doing research on software-defined clouds. As part of it, Open vSwitch (OVS) is integrated with Raspberry-Pis, low-cost embedded computers, to build up a network of OpenFlow switches. We provide two use cases and perform validation and performance evaluation. We also discuss benefits and limitations of CLOUDS-Pi in particular and SDN in general.
