The current laboratorial lecture taught how to deploy a Ryu SDN application that offers an on-demand elastic service, which is designated as the fog datacenter. The fog datacenter automatically detects the need to activate a part of the network topology before routing some traffic destined to some destination node. This destination node is also activated before the SDN application controlling the necessary switches to deploy the routing path through the network infrastructure to that receiving node. This fog datacenter could offer heterogeneous resources, such as networking, computation, and storage, where and when those resources are necessary, at the network edge.
