An architecture for providing an on-demand dynamic cloudlet instantiation by leveraging a grouping of software defined network devices and their respective associated analytics modules. A method can comprise receiving quality of service data representing a 5G small cell device of a group of 5G small cell devices; generating a policy rule representing a predictive policy to facilitate an instantiation of a dynamic on-demand cloudlet node into a fog of dynamic on-demand cloudlet node instantiations; and facilitating the instantiation of the dynamic on-demand cloudlet node into the fog, by a hybrid fiber coaxial device, based on the policy rule and an indication received from the hybrid fiber coaxial that a traffic surge in communications with the 5G small cell device has occurred.
