Internet of Things (IoT) requires cloud infrastructures for data analysis (e.g., temperature monitoring, energy consumption measurement, etc.). Traditionally, services have been implemented in large datacenters the core network. Core offers high-computational capacity with moderate response time, meeting requirements centralized low-delay demands. However, collecting information and bringing it into one infrastructure is not a long-term scalable solution, particularly as volume IoT devices...
