Digital technologies, such as cloud computing, have transformed business activities, particularly in the public domain. In the corporate sector, where cloud computing technology has long been implemented, some organisations have succeeded, while others have been less successful. Saudi Arabia has enthusiastically supported the move to cloud computing technology; however, from a business perspective, its implementation of government cloud technology is still relatively nascent and has faced numerous challenges. The existing literature suggests that the government cloud migration depends not only on project drivers, but also on considerable barriers, which often delay successful implementation. Furthermore, many current barriers and drivers clearly involve the roles of cloud vendors, meaning that cloud vendors must be fully engaged in order to develop comprehensive solutions. Addressing this phenomenon from the lens of enterprise architecture (EA) may support the development of appropriate deployment requirements for optimal government cloud implementation. Thus, this paper is a research in progress that analyses the major barriers and drivers affecting cloud implementation in public organisations, taking into consideration the perspectives of cloud consumers and vendors. This paper also introduces a mapping conceptual model throughout The Open Group Architecture Framework (TOGAF) that supports a novel framework for tackling these barriers and their influences and enhancing drivers via a set of requirements.
