Based on a structured literature analysis, this review paper takes stock of the current landscape of cloud service research: 66 IS journals and conference proceedings were examined on the topic of cloud services and the identified 158 relevant articles were systematically categorized on ten perspectives from the whole world, the industry, the organization, the IT department to the single cloud service. The descriptive findings show a focus of cloud service studies on private organizations as primary user group of the cloud in the information and communication industry pointing out the lack of cloud service research in the public sector and administrations and the need for egovernment specific implications. Results at the service level further show that the majority of all existing articles refer to infrastructure as a service (IaaS), platform as a service (PaaS) and software as a service (SaaS) in general and hence, neglect to explicitly specify the particular cloud capability provided.
