“…Andrikopoulos et al [6] pointed out that the decision whether to migrate, which cloud services to use and at which level to outsource is not trivial and that it largely depends on multiple factors that are specific to the context of each enterprise. Further, organisations have different business processes and interdependent criteria and constraints to consider when moving their systems to cloud environments [50]. The analysis of the Stage 1 also revealed that organisations have different expectations and understanding about the cloud environment.…”

“…According to [51] the systematic and efficient modernisation of legacy applications to exploit current cloud-based technologies remains a major challenge. Applications consist of several components that are connected with each other to comply with the application's functional and non-functional requirements [50]. These components need to be correctly adapted according to the target cloud environment.…”

“…These components need to be correctly adapted according to the target cloud environment. Failure or incorrect adaptation might result in difficulties in meeting some quality or economic requirements [50]. Typical adaptation problems range from compatibility and interoperability issues to licensing that may forbid organisations from moving registered software components.…”

“…These kinds of issues usually occur when a service component is shifted to the cloud while another dependent component is kept on-premises to meet security requirements [50]. Zhao and Zhou [52] identified the need for a holistic methodology from redesign and adaptation to application for special migration, architecture refactoring, integrated development environment and support migration of legacy applications to the cloud environment.…”

Migrating existing resources to cloud computing is a strategic organisational decision that can be difficult. It requires the consideration and evaluation of a wide range of technical and organisational aspects. Although a significant amount of attention has been paid by many industrialists and academics to aid migration decisions, the procedure remains difficult. This is mainly due to underestimation of the range of factors and characteristics affecting the decision for cloud migration. Further research is needed to investigate the level of effect these factors have on migration decisions and the overall complexity. This paper aims to explore the level of complexity of the decision to migrate the cloud. A research model based on the diffusion of innovation (DOI) theory and the technology-organization-environment (TOE) framework was developed. The model was tested using exploratory and confirmatory factor analysis. The quantitative analysis shows the level of impact of the identified variables on the decision to migrate. Seven determinants that contribute to the complexity of the decisions are identified. They need to be taken into account to ensure successful migration. This result has expanded the collective knowledge about the complexity of the issues that have to be considered when making decisions to migrate to the cloud. It contributes to the literature that addresses the complex and multidimensional nature of migrating to the cloud.

Cloud computing provides an innovative delivery model that enables enterprises to reduce operational costs and improve flexibility and scalability. Organisations wishing to migrate their legacy systems to the cloud often need to go through a difficult and complicated decision-making process. This can be due to multiple factors including restructuring IT resources, the still evolving nature of the cloud environment, and the continuous expansion of the services offered. These have increased the requirement for tools and techniques to help the decision-making process for migration. Although significant contributions have been made in this area, there are still many aspects which require further support. This paper evaluates the existing level of support to aid the decision-making process. It examines the complexity of decisions, evaluates the current state of Decision Support Systems in respect of migrating to the cloud, and analyses three models that proposed support for the migration processes. This paper identifies the need for a coherent approach for supporting the whole decision-making process. Further, it explores possible new approaches for addressing the complex issues involved in decision-making for migrating to the cloud.
