Cloud computing service is a model of a shared network-delivered service in which users focus only provided services and need not worry about the implementation of the services. The service model and life cycle become changing by cloud computing service. The paper proposes a new type of approach to accelerate the service innovation with Sensor-Cloud Infrastructure which provides IT resources and sensors as cloud computing service. Service provider prepares service templates. Service requesters can get service instances quickly when they require. Service requesters can use service instances themselves or extend service instances for creating new services. This paper describes a service model with the Sensor-Cloud Infrastructure, accounting, service life cycle and service innovation with usecase scenarios. © 2011 IEEE.
