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 of Virtual 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 of Virtual Machine (Cont.)
• Isolation
Fault and security isolation at the hardware level
Advanced resource controls preserve
performance
8. Key Properties of Virtual 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 of Virtual 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
12. VMware Workstation
• VMware Workstation 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
• VMware Tools 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)
