Abstract

­Quality of Service (QoS) is a significant concept in distributed systems. Therefore, several studies within QoS for distributed systems have been researched over the past years. It is very difficult to deliver an appropriate QoS level for frameworks running in different open resource environments, including the Internet. A distributed system’s QoS characteristics are affected by the QoS of the specific hosts involved, and the QoS of the networking subsystem linking these hosts. This paper reviews the state-of-the-art of distributed systems evolution in QoS architecture. In the context of distributed systems, the method adopted is to address QoS terms and a generalized QoS system for identifying and explaining QoS.

Abstract

­Distributed cloud computing innovation is the best approach to provide everything to customers as services through a web association. Utilizing this innovation, the customers would have the option to lease the necessary services through internet browsers. Cloud computing is aimed mainly at delivering customer services on demand. Cloud computing is a general concept that provides a wide range of infrastructure-based services, through platform as a production tool, via software as a service providing customers with the licenses of an application as an on-demand service. Various service models such as IaaS, PaaS, and SaaS, and many more are used in Cloud Computing. The features of these service models that distinguish cloud computing from other areas of study are proposed to clarify the essential aspect of Cloud Computing. These service models are compared from different viewpoints so that they can better identify their origins. In this article, three key service models are compared and discussed, i.e., software as a service, platform as a service, Infrastructure as a service, and previous studies on these services demonstrated and compared based on methods, objects, and significant results.

 Keywords: Cloud computing, Infrastructure as a Service (IaaS), Platform as a Service (PaaS), software as a Service (SaaS).
