Abstract—With the increase in the number of cloud service offerings by the cloud service providers nowadays, selecting the appropriate service provider becomes difficult for customers. This is true since most of the cloud service providers offer almost similar services at different costs. Thus, making cloud service selection a tedious process for customers. The selection of the cloud services from the security standpoint needs a distinct consideration from both the academia and the industry. Security is an important factor in cloud computing. Thus, any exploited vulnerability will have a negative effect on cloud computing adoption by customers. Hence, little attention has been paid to cloud service monitoring and selection from a security perspective. To solve this issue, we propose a security measurement as a trust (SMaaT) in the cloud computing selection. Finally, we propose Analytical Hierarchical Process (AHP) for service selection from the customers’ perspective.
