摘要：From previous advancements in technology and from the likes of parallel computing, distributed computing and grid computing, a new technology has emerged, called cloud computing. In this paper, at first we discuss about eight models in cloud computing, which are built upon three major services namely IaaS, PaaS, SaaS and including other minor services such as, Hardware-as-a-Service (HaaS), Virtual Cluster-as-a- Service (ViteraaS). Then, paper tries to presents a solid comparison of these models according to a set of most common factors that any cloud models should have, identified from thoroughly researched multiple cloud-based articles. Finally, an evaluation of the comparison and exposes all the possible future works or implementation that can be considered, has proposed. The paper discusses factors that must be considered to choose the most suitable model for implementing certain functionality in cloud computing.
