Cloud-based SOA refers to an application architecture within which all functionalities are defined as independent serviceswith cloud-based APIs that can be used to leverage external computing resources through ubiquitous Internet access. Thispaper uses cloud-based SOA as a new form of IT-enabled enterprise transformation to reconceptualize the roles of ITdepartments. A proposed conceptual framework argues that IT departments and cloud-based SOA are mutually influenced.Upon reviewing relevant literature, this paper suggests that research should reexamine critical success factors in cloud-basedSOA implementations and investigate influences of cloud-based SOA implementations in the reconstruction of ITdepartments. Research questions and propositions are developed to guide research in this area
