Fog computing brings cloud closer to end-users and data sources by enabling computation at the edge of the network. Low latency is the main benefit. IoT applications are often latency-sensitive. Such applications may be provisioned as component-based in a hybrid cloud/fog environment with components spanning cloud and fog. This will enable placing some of its components in the fog domain closer to the IoT devices, and consequently reduce the latency. However, provisioning applications in hybrid cloud/fog environment is still manual today. Existing PaaS do not support interacting with fog nodes, at the edge, for applications' components provisioning. This demo shows the key features of the hybrid Platform as-a-Service (PaaS) we have designed for IoT applications provisioning in cloud and fog environments. Three goals are assigned to the demo: (1) How applications can be designed and developed in …
