Most of the solution deployments do not understand and realize the importance of IoT Device Management until it hinders the system. The spectrum of the IoT gateway applications ranges from simple sensors to complex machines and many. IoT-Gateway Device Management is totally a different aspects in terms of – a variety of devices, number of IO requests, the number of message transactions, business logic, security, peripheral scape, connectivity, scalability, and many. So, IoT Gateway/Device Management is far exceeding that of MDM.
