Virtualization
Virtualization, refers to the act of
creating a virtual (rather than actual)
version of something.
Virtualization is the simulation of the
software and/or hardware upon
which other software runs.

Network virtualization
Virtualize one hardware network
equipment into many virtual network
equipments
Virtualize many hardware into one
virtual network equipment

Network virtualization benefits
Improve network resource usage
Internal : traffic between VMs through
vNICs
External : many networks without the
need to build many physical
Improve security : isolate traffic
based on groups : e.g. isolate depts

What is storage virtualization
Making abstraction separating :
Host implementation (application, OS)
Network implementation (switch, router,
gateway)
Storage implementation (array, library, device)
Make invisible to host : physical pathing,
device characteristics, physical data
location
Location and implementation transparency

Storage virtualization stack
SNIA storage stack

Storage virtualization benefits
Increase storage asset utilization
Reduce power / cooling costs
Reduce management complexity
Openness to server, network and storage
technology
Reduce down time
Dynamic provisioning (elastic cloud, on
demand)
Increase scalability

OS virtualization
NIST definition : Full virtualization
Virtualization is the simulation of the
software and/or hardware upon
which other software runs.
NIST SP 800-125
Each OS appears to have :
CPU, memory,
storage (hard disk, USB, CD-ROM,…storage controller,
Ethernet controller, display and sound, keyboard and
mouse, parallel ports, …

Types of OS virtualization
NIST SP 800-125

16
Benefits of OS virtualization
Consolidation : reduce CAPEX
Efficiency : Rise hardware usage
Flexibility : reduce management and OPEX
costs
Security : Isolation prevent :
Avoid crash
DDOS attacks
Side channel Attacks
Weakness : hypervisor is SPOF if compromised
all is down.


OS
Hardware
User equipment only includes a
keyboard, a mouse and a monitor
Creates a reliable and scalable shared resource pool to
perform unified management.

Decouples hardware from the OS to perform central delivery.

Decouples applications from the OS to perform central
delivery.

Decouples data from the OS to perform central storage.

Creates multi-level security systems to perform distributed
security control.

Application virtualization
Application virtualization layer to run
specific software (layer replaces the
run time environment)
Separate applications from OS
The container will ensure OS security
allows applications to run in
environments that do not suit the native
application: e.g. Wine allows some
Microsoft Windows applications to run
on Linux.

Cloud computing
Model for enabling ubiquitous,
convenient, on-demand network
access to a shared pool of
configurable computing resources
(e.g., networks, servers, storage,
applications, and services) that can
be rapidly provisioned and released
with minimal management effort or
service provider interaction
NIST SP-500-291

Cloud Cost model
Traditional licensing associated with
ownership, number of users,
support, and maintenance costs and
services are being challenged by the
pay-as-you-go model found in ondemand Cloud Computing
