Cloud Computing (CC) is very important to IoT. In this regard, the following CC Services should be emphasized:
Support for various IoT Services (Smart Cities, Internet of Energy, Internet of Health, Green IoT, ...)
SDN-based Orchestration of Fog Computing (FC) Nodes,
Orchestration of IoT Microservices,
Big Data (BD) Analytics for various Intelligent IoT Services,
Support of Information Centric based IoT Services (Smart Cities, Smart Healthcare, ...),
Support of AI-enabled IoT Services
CC, FC, AI and BD Analytics are the driving forces of IoT evolution to Intelligent IoT. This illustrates my poster: Internet of Things (IoT) – Quo vadis?
