Virtualization
 Ability to run ‘multiple OS’ on a ‘single physical system’ and
share the underlying hardware resources
What is VMware
 VMware is virtual machine software
 Each virtual machine has its own set of virtual
hardware
 Allows multiple virtual machines, operating systems
to run in isolation and side-by-side on the same
physical machine.
Without VMware
 All require same power
 All emits same heat
 All require physical
space
 Setup , Configuration
 Maintenance, support…
With VMware
 Flexibility
 Operational Efficiency
 Disaster Recovery
 Optimizes the use of
Physical resources
 Easy to configure
Key Features
 Partitioning
 Isolation
 Encapsulation
 Hardware Independence
Partitioning
 Run multiple Operating
Systems on one Physical
machine
 Divide system resources
between virtual machines
Isolation
 Each virtual machine is isolated
from other virtual machines
on the same server
Encapsulation
 Virtual machines encapsulate
entire systems (hardware
configuration, operating
system, apps) in files
Hardware Independence
 Run a virtual machine on any
server without modification

How does it works
 Allows multiple operating system instances to run
concurrently within virtual machines on a single
computer
 A virtualization layer is installed, which uses either a
hosted or hypervisor architecture
Comparison
 Difficult to move or copy
 Bound to a specific set of
hardware
 Often has short life cycle
 Requires personal contact
to upgrade hardware
 Difficult to manage
remotely
Virtual Machine
• Easy to manage
• Isolated from other virtual
machines running on the
same physical hardware
• Insulated from physical-
hardware changes
Physical Machine
• Easy to move and copy
• Encapsulated into files
• Independent of physical
hardware
Consolidation
