Unikernel as Service Units on Distributed Resource-constrained Edge Devices

There are almost 31 billion IoT devices in the world. Due to its widespread use the concept virtualization and cloud computing is moving towards the IoT systems support. There are lots of challenges that appears in terms of deploying the computational units in IoT devices due to its resource constrained nature and the absence of high processing power. A new technology called unikernel provides the support to meet these challenges. Unikernel combines the applications stack with a specialised kernel that has the only required libraries of operating systems to run the application stack. The end result is a low memory footprint image that can be deployed in memory constrained IoT devices. In industrial server hundreds of IoT devices run on same network and share their computational units with each other. Managing and orchestrating these services running in IoT devices requires additional overhead application units which makes the whole automation process much complex. Arrowhead framework is an industrial automation tool provides the solution to this challenges. With its service oriented architecture(SOA) approach the framework provides collaborative automation to maintain inter connectivity between computational units in IoT devices in a form of System of Systems(SoS). Arrowhead framework introduces a local cloud concept that deducts the additional application stack overhead to achieve the automation processes like service discovery, registry and orchestration
