Virtualization in Cloud Computing : Developments and Trends

Cloud computing is an interesting paradigm that is making computing and other related activities easy for consumers. The cloud infrastructure is not new, but it is working on new technology based on various services offered. The cloud provides application software online for users to conduct common activities like word processing. Cloud computing also enables consumers to leverage on cloud infrastructure by designing and deploying their application on the cloud. A unique feature of the cloud is the provision of scalable storage for data which are usually spread across several geographical locations. A core technology used on the cloud is virtualization. This allows virtual machines to be hosted on physical servers. This provides great benefits to users on the cloud. This paper presents the state of the art from some literature available on cloud virtualisation. The study was executed by means of review of some literature available on cloud virtualisation. The study was performed by means of review of some literature using reliable methods. This paper examines present trends in the area of cloud virtualisation and provides a guide for future research. In the present work, the objective is to answer the following question: what is the current trend and development in cloud virtualisation? Papers published in journals, conferences, white papers and those published in reputable magazines were analysed. The expected result at the end of this review is the identification of trends in cloud virtualisation. This will be of benefit to prospective cloud users and even cloud providers.
