A Review on Virtualization: A Cloud Technology

Abstract

Cloud computing is used to utilize the shared resources to a maximum possible extent. These resources are shared by more than one user at a time as per their need. This improves computing power for using various applications at various places with additional advantage of cost saving on storage space and electricity consumption. Virtualization is one of the important technologies of cloud computing, which directs to act virtually instead of actually doing something. Through virtualization software, sharing of the system resources is done across multiple environments. This paper mainly focuses on introduction to virtualization, advantages & disadvantages of virtualization and types of virtualization like: server, desktop, application, programming language, storage, network virtualization etc. Server virtualization involves partitioning a main server into different virtual servers. Desktop virtualization jointly with application virtualization is used to provide a desktop environment management system. Applications in the application virtualization are executed on different operating system as if it is executing on original operating system. Storage virtualization makes available data from multiple network storage devices into one single storage unit. Network virtualization is the process of combining hardware and software network resources into a single virtual network through software. In addition to this, the paper provides future research direction in virtualization.
