A method, a computer program product, and a computer system for allowing multiple infrastructural services to access multiple IoT (Internet of Things) devices. A gateway device connects the multiple infrastructural services and the multiple IoT devices. The gateway device receives a use request from a first application of a first infrastructural service. Among the multiple IoT devices, the gateway device identifies an IoT device that meets one or more requirements in the use request. The gateway device determines whether the IoT device is being used by a second application of a second infrastructural service. The gateway device assigns to the first application an exclusive right to use the IoT device, in response to determining that the IoT device is not being used by the second application. The first application has a right to refer to data and a right to execute available commands without restriction.
