A Proposed Cloud Quality Model (IaaSQual) for “Infrastructure as a Service (IaaS)” from User's Perspective

Infrastructure as a Service (IaaS) is a service provided by cloud computing systems vendors. IaaS provides virtual computing resources to the users such as hardware, servers, data center space and storage, and network components all over the internet. Just like any other growing technology, cloud computing and specifically IaaS faces some challenges that affect the quality of service and must be conquered to achieve users' satisfaction and the most reliable service. Therefore, the service must be dependable to satisfy the business. In this study, a quality model will be proposed from the users' perspective to help the IaaS vendor to understand the IaaS users' nonfunctional requirements.
