The Identification of Quality Attributes for SaaS in Cloud Computing

Cloud computing is a new paradigm for delivery of applications, platforms, or computing resources (processing power/bandwidth/storage) to customers in a "pay-as-you-go-model". It can be categorized Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (PaaS). Especially, SaaS is a potential segment and have many advantages such as investment reduction, performance improvement, time saving, easier collaboration, global accessibility, and so on. However, in spite of these importance and advantages, there are few researches about identification for the quality and making quality attributes for SaaS in cloud computing. In this paper, we propose identification of quality attributes for QoS of SaaS in cloud computing. In order to construct their quality's attributes fitting on SaaS characteristics, we extract their attributes from ISO/IEC 9126 and design the QoS model for SaaS.
