Virtualization in cloud environment: Bandwidth management

Abstract

Cloud computing recently emerged as an interesting model that enables computing and other related internet activities to take place anywhere, anytime. Cloud service providers centralize all servers, networks, and applications to allow their users’ access at any time and from any location. Cloud computing uses already existing resources like server, CPU and storage memory but runs on a new technology known as virtualization. The core idea of virtualization is to create several virtual versions of one single computing device or resource. This enables many user operating systems to work on such a single underlying piece of device. Network bandwidth is one of the critical resources in a cloud environment. Bandwidth management involves the use of techniques, technologies, tools, and policies to help avoid network congestion and ensure optimal use of the subscribed bandwidth resources while also being a bedrock of any subscription-based access network. Bandwidth management is being utilized by organizations to allow them to efficiently utilize their subscribed bandwidth resources. Bandwidth management deals with the measurement and control of packets or traffic on a network link in order to refrain from overburdening or overloading the link which can lead to poor performance and network congestion. In this paper, the highest development with respect to virtualization in cloud computing is presented. This study review papers available on cloud computing and relevant published literature in multiple areas like conferences, journals etc. This paper examined present mechanisms that enable cloud service providers to distribute bandwidth more effectively. This paper is therefore a study of virtualization in cloud computing, and the identification of bandwidth management mechanisms in the cloud environment. This will benefit forthcoming cloud providers and even cloud users..
