- 3. What is Virtualization •Virtualization is a proven software technology that makes it possible to run multiple operating systems and applications on the same server at the same time. • It’s transforming the IT landscape and fundamentally changing the way that people utilize technology.

- 4. Benefits of Virtualization •Reduce capital and operating costs. • Deliver high application availability. • Minimize or eliminate downtime. • Increase IT productivity, efficiency, agility and responsiveness. • Speed and simplify application and resource provisioning. • Support business continuity and disaster recovery. • Enable centralized management. • Build a true Software-Defined Data Centre.
- 5. The Virtual Machine •A virtual machine (VM) is an emulation of a particular computer system. • Virtual machines operate based on the computer architecture and functions of a real or hypothetical computer, and their implementations may involve specialized hardware, software, or a combination of both. • Multiple virtual machines can operate concurrently on a single x86 host system. • Each one can run a different operating system and application stack.
- 6. Key Properties ofVirtual Machine • Partitioning  Run multiple operating systems on one physical machine  Divide system resources between virtual machines  ESX Server stands for Enterprise Server X.
- 7. Key Properties ofVirtual Machine (Cont.) • Isolation  Fault and security isolation at the hardware level  Advanced resource controls preserve performance
- 8. Key Properties ofVirtual Machine (Cont.) • Encapsulation  Entire state of the virtual machine can be saved to files  Move and copy virtual machines as easily as moving and copying files
- 9. Key Properties ofVirtual Machine (Cont.) • Hardware-Independence  Provision or migrate any virtual machine to any similar or different physical server
- 10. Types of Virtualization •Server Virtualization • Network Virtualization • Software-Defined Storage • Desktop Virtualization • Hardware Virtualization
- 11. Virtualization Technology Companies •VMware (VMWare Workstation) • Citrix • Oracle (Virtual Box) • Microsoft • Red Hat • Amazon • Google
- 12. VMware Workstation • VMwareWorkstation is a hypervisor that runs on x86-64 computers. • It is developed and sold by VMware, Inc., a division of EMC Corporation. • It enables users to set up one or more virtual machines (VMs) on a single physical machine, and use them simultaneously along with the actual machine. • Each virtual machine can execute its own operating system, including versions of Microsoft Windows, Linux, BSD, and MS-DOS. • The Latest Version of VMWare is 11.1.2 which released on 15th June 2015.
- 13. VMware Tools • VMwareTools is a package with drivers and other software that can be installed in guest operating systems to increase their performance. It has several components, including the following: • Drivers for the emulated hardware • VESA-compliant graphics for the guest machine to access high screen resolutions • Network drivers for the vmxnet2 and vmxnet3 NIC • Mouse integration
- 14. VMware Tools (Cont.) •Drag-and-drop file support • Clipboard sharing between host and guest • Time synchronization capabilities (guest syncs with host machine's clock)
