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.
NIST SP 800-125

Network virtualization
Virtualize one hardware network equipment into many virtual network equipments Virtualize many hardware into one virtual network equipment (consolidate)

Network virtualization benefits
Improve network resource usageInternal : 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 locationLocation and implementation transparency

Storage virtualization benefits
Increase storage asset utilizationReduce power / cooling costsReduce management complexity
Openness to server, network and storage technologyReduce down timeDynamic provisioning (elastic cloud, on demand) Increase scalability

OS virtualization
NIST definition : Full virtualizationVirtualization 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, …

NIST SP 800-125
Benefits of OS virtualization
Consolidation : reduce CAPEXEfficiency : Rise hardware usageFlexibility : reduce management and OPEX costs Security : Isolation prevent :
Avoid crash DDOS attacksSide channel AttacksWeakness : hypervisor is SPOF if compromised all is down.

Hardware
Dispersed deployment and maintenance,local storage
Traditional desktop infrastructure: hard to maintain, can not guarantee security and lacks mobility.
Complex O&M
Security risk
Difficult to service

Huawei desktop cloud platform
Hardware
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 delive
ry. Decouples data from the OS to perform central storage. Creates multi-level security systems to perform distributed
security control.
User interface (UI) is transmitted to terminal devices by using remote protocols, such as ICA, RDP, or PCoIP.
User equipment only includes a keyboard, a mouse and a monitor

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