Risks in Enterprise Cloud Computing: The Perspective of it Experts

Abstract: Cloud computing has become an increasingly prevalent topic in recent years. However, migrating hitherto internal IT data and applications to the cloud is associated with a wide range of risks and challenges. The study reported in this paper aims to explore potential risks that organisations may encounter during cloud computing adoption, as well as to assess and prioritise these risks, from the perspective of IT practitioners and consultants. A questionnaire was designed and distributed to a group of 295 highly experienced IT professionals involved in developing and implementing cloud based solutions, of which 39 (13.2%) responses were collected and analysed. The findings identified a set of 39 cloud computing risks, which concentrated around diverse operational, organisational, technical, and legal areas. The most critical top 10 risks perceived by IT experts were found to be caused by current legal and technical complexity and deficiencies associated with cloud computing, as well as by a lack of preparat...

Cloud Erp: A New Dilemma to Modern Organisations?

Abstract: For almost two decades, on-premise ERP has been adopted very prevalently in the industry. Accompanied with the emergence of cloud computing technologies in the late 2000s, there is an increasing trend for companies to migrate their hitherto internal ERP applications and databases into the cloud. Such ERP resources re-migration, which can offer a range of opportunities to user companies, is also associated with new challenges. The study reported in this paper aimed to explore potential benefits and barriers associated with the adoption of cloud ERPs. A set of in-depth interviews were conducted with 16 ERP and cloud consultants. The findings, derived from a thematic analysis, identified that whilst the economic and technical benefits promised by cloud vendors are attractive, the success of cloud ERP adoption can be affected by critical challenges related to diverse organisational factors as well as with current legal and technical complexity in the cloud environment.

Exploring Critical Risks Associated with Enterprise Cloud Computing

Abstract: While cloud computing has become an increasingly hot topic in the industry, risks associated with the adoption of cloud services have also received growing attention from researchers and practitioners. This paper reports the results of a study that aimed to identify and explore potential risks that organisations may encounter when adopting cloud computing, as well as to assess and prioritise the identified risks. The study adopted a deductive research method based on a cross-sectional questionnaire survey. The questionnaire was distributed to a group of 295 carefully selected and highly experienced IT professionals, of which 39 (13.2 %) responses were collected and analysed. The research findings identified a set of 39 cloud computing risks, which concentrated around diverse operational, organisational, technical, and legal areas. It was identified that the most critical risks were caused by current legal and technical complexity and deficiencies associated with cloud computing, as well as by a lack of preparation and planning of user companies.

Technological, organisational and environmental factors influencing managers’ decision to adopt cloud computing in the UK

Abstract: Purpose – The purpose of this paper is to determine the factors influencing managers’ decision to adopt cloud computing in the UK using the “Technology-Organisation-Environment” (TOE) framework. Design/methodology/approach – Data were collected through a self-created questionnaire based survey that was completed by 257 mid-to-senior level decision-making business and information technology (IT) professionals from a range of UK end-user organisations. The derived hypotheses were tested using various data analysis techniques including principal component analysis and logistic regression. Findings – The results show that four out of the eight factors examined have a significant influence on the adoption decision of cloud computing services in the UK. Those key factors include competitive pressure, complexity, technology readiness and trading partner pressure. The latter predictor; trading partner pressure, was the most significant factor for the adoption decision of cloud services reflecting organisations’ c...
