Virtualization and their security threats

Few issues in the IT arena are regarded with more interest and passion than virtualization. Virtualization refers to technologies designed to provide a layer of abstraction between computer hardware systems and the software running on them. Here, we are discussing the key concepts of virtualization if you want to implement the virtualization within your environment. Many different vendors have many different virtualization products according to their size of business viz. small, medium or large. In case of server consolidation, many small physical servers are replaced by one larger physical server, to increase the utilization of costly hardware resources such as CPU. In section1, we give introduction to virtualization and their types. Section2 describes application performance using Xen VMM. Section3 describes how we can virtualize datacenter and some of their solutions. In section 4 and 5, we describe some of the security threats and some of the benefits and finally we conclude our discussion.
