VIRTUALIZATION TECHNIQUES & TECHNOLOGIES: STATE-OF-THE-ART

Abstract

Today virtualization is not just a possibility but it is becoming mainstream in data centers across the business world. Virtualization technology is popular today for hosting Internet and cloud-based computer services. Technology is evolving at a rapid rate and virtualization is no longer just about consolidation and cost savings, It is about the agility and flexibility needed for service delivery in data centers, including production environment and the infrastructure that supports the most mission-critical applications. Virtualization is a rapidly evolving technology that provides a range of benefits to computing systems, such as improved resource utilization and management, application isolation and portability and system reliability. Among these features, live migration, resources management, IT infrastructure consolidation are core functions. Virtualization technology also enables IT personnel to respond to business needs more rapidly with lower cost and improved operational efficiencies. Virtualization technologies are changing the IT delivery model to provide on-demand self-service access to a shared pool of computing resources via broad network. The analysis of this survey will enable a better understanding of basic concept of virtualization, virtualization techniques, technologies, services and motivate especially Information Technologies (IT) staff as a detailed framework for the companies working in different industrial sectors. The evolution of datacenter transformation from traditional approach to virtualization i.e. from dedicated processing to pooled processing with strategic business values and methodologies are analyzed in details in this paper. This paper also discusses what virtualization is, how organizations can benefit from adopting virtualization into future IT plans.
