Behind the Surveys: Cloud Adoption at Second Glance

Cloud Computing has evolved from a trend technology to a well established part of the international market and still has growing relevance. For strategic decisions especially of information technology providers as well as governments, surveys can provide relevant information, but as usual in surveys, there are noteworthy differences even for the simplest questions. In this paper we give an overview of several existing cloud surveys and compare some of the questions, particularly related to cloud adoption and scepticism. Differences are highlighted and a list of influencing factors as possible reasons is derived, each with some background, reference proofs and explanation.
