Virtualization Techonlogy And Its Application In Finacial Institutions

Virtualization is an abstract concept that devices are running in a virtual environment rather than a real one. It separates the physical hardware from the operating system so as to provide higher resource utilization and flexibility. The virtualization technology has almost six dacades of history. Now it consists of server virtualization, storage virtualization, network virtualization, and application virtualization technology. Virtualization can improve the efficiency of computers, reduce costs and energy consumption, simplify system management, and improve reliability, availability and security. It is one of the tools to accomplish green IT and establish an energy-saving society efficiently.This thesis firstly introduces the current status of banking and other financial institutions in the information technology development and studies these issues. Secondly it proposes applying virtualization technology to financial institutions in order to solve these problems. It chooses different virtualization solutions against various application scenarios and features in the financial institutions. Finally, it analyses feasibility of deploying cloud computing to the financial institutions based on current IT infrastructure, and solve the issues by private cloud computing in terms of its advantage, which are not able to be done merely by virtualization technology, in application of financial insitution.
