Service Oriented Quality Requirement Framework for Cloud Computing

Abstract

This research paper introduces a framework to identify the quality requirements of cloud computing services. It considered two dominant sub-layers; functional layer and runtime layer against cloud characteristics. SERVQUAL model attributes and the opinions of the industry experts were used to derive the quality constructs in cloud computing environment. The framework gives proper identification of cloud computing service quality expectations of users. The validity of the framework was evaluated by using questionnaire based survey. Partial least squares-structural equation modelling (PLS-SEM) technique was used to evaluate the outcome. The research findings shows that the significance of functional layer is higher than runtime layer and prioritized quality factors of two layers are Service time, Information and data security, Recoverability, Service Transparency, and Accessibility.
