Abstract
With today's rapid advances in Information and Communication Technologies (ICT), an increasing number of governments worldwide are seeking solutions to enhance their IT infrastructures and services, and reshape their e-government systems to meet public needs of providing easily accessible, cost-effective, high quality, and reliable e-services. In recent years, government cloud (G-Cloud) has emerged as a new and innovative computing paradigm with a promising opportunity for many governments to rationalize the way they manage their services and resources. Government cloud's potential benefits has been recognized by many governments around the world. This paper will study the acceptance of cloud computing technologies and services in Saudi government agencies by investigating the significant and influential factors that affect the behavioral intentions to use G-Cloud. Moreover, in light of the rising concerns over trust issues in cloud computing which have been reported to be one of the major barriers to the adoption of the cloud, the study proposes an extended Unified Theory of Acceptance and Use of Technology (UTAUT) model by incorporating trust as a key factor in the acceptance of G-Cloud.
