Organizational Determinants of Corporate IaaS Usage

This paper presents and tests a set of hypotheses explaining corporate IaaS (Infrastructure-as-a-Service) acceptance and adoption. The empirical results are based on an online survey involving 226 IT executives and IT infrastructure experts. We identify (1) perceived usefulness and ease of use as drivers of attitude towards IaaS usage, (2) attitude, perceived usefulness, and subjective norm as strongest drivers of intention to use, and, (3) intention to use as driver of IaaS adoption. The theoretical and practical implications of this model are discussed.
