This demo will show the key features of a Platform as-a-Service (PaaS) we have proposed in a research paper accepted for presentation at IEEE LANMAN 2016 conference. The proposed PaaS enables IoT applications provisioning in hybrid cloud/fog environments. Two goals are assigned to the demo. On the one hand, we will highlight how IoT applications can be provisioned in such environments. On the other hand, we will show concretely the advantages these hybrid environments have over traditional cloud environments. The provisioning in these hybrid environments enables latency reduction and processing performance enhancement. Indeed, in order to reduce latency, the applications can have some of its components running in a distant cloud and interacting with the other components running in the fog, closer to IoT devices.
