Virtualization allows multiple operating systems to run simultaneously on a single physical machine through the use of a hypervisor layer. It provides benefits like server consolidation, application consolidation, sandboxing, and mobility. The main technologies that enable virtualization are the hypervisor and virtual machines. Virtualization can be implemented through full virtualization, para-virtualization, software virtualization, or hardware virtualization. It has become a widely used technology in areas like desktops, servers, and cloud computing.

2. Virtualization: what is it, really? Virtualization is a broad term in computing which refers to abstraction of computing resources across many aspects of computing. For our purposes - One physical machine to run multiple operating systems simultaneously.

3. Virtualization: Why? Server consolidation Application Consolidation Sandboxing Multiple execution environments Virtual hardware Debugging Software migration (Mobility) Testing/Quality Assurance

4. Core Technology The Hypervisor A computing layer which allows multiple operating systems to run on a host computer at the same time. Originally developed in the 1970s as part of the IBM S/360 Many modern day variants from different developers

5. Traditional Server Conceptual diagram of typical server configuration without virtualization

6. The Hypervisor The role of the Hypervisor in supporting Guest Operating Systems on a single machine.

24. Virtualization is “HOT” Oracle acquires Sun Microsystems. Microsoft acquires Connectix Corp. Sun Microsystems acquires Innotak Citrix Systems acquires Xen IBM, already a pioneer HP picking up  Virtualization is HOT!!!

25. Conclusions Virtualization is today most demanded Technology. Virtual Machines are gift for researchers and students. Provides lot of support to developers and bug finders. Can be used to port one software on diverse systems. Used widely in Server computing. Provide isolated execution environment to run untrusted applications. Help in development of new technology and services like Cloud computing and SaaS.
