Provisioning resources elastically in IoT cloud systems

Convergence of the IoT and cloud infrastructure will enable effective realization of the IoT systems and meet its high resource demands. However developing IoT cloud systems involves numerous challenges like ensuring security, elasticity, etc. In this paper we have introduced the principles of engineering elasticity in IoT cloud systems and a conceptual model to realize them. By incorporating modules for application specific analytics, autonomous resource de/provisioning and monitoring the allocated resources we have demonstrated how elasticity can be ensured. The theoretical proof of concept along with a scenario of smart cars and a car manufacturing plant demonstrates the functioning and advantages of the aforementioned in a real-world IoT cloud system.
