3 rd Generation Virtual Computing (The new IT frontier) By Matthew Bulat M.Eng.Tech MCSE MCDBA http://www.matthewb.id.au/

What is virtualisation? A host computer running isolated guest operating systems applications A Virtual Machine (VM) is the representation of a physical machine by software VM can work independently of the host architecture

A host computer running isolated guest operating systems applications

A Virtual Machine (VM) is the representation of a physical machine by software

VM can work independently of the host architecture

Why Virtualization? Use hardware efficiently Save electricity at the server/UPS/cooling system Setup new computer projects quickly Run development systems up offline on desktop PC Save money on yearly hardware budgets Save space in computer room Less network hardware needed

Use hardware efficiently

Save electricity at the server/UPS/cooling system

Setup new computer projects quickly

Run development systems up offline on desktop PC

Save money on yearly hardware budgets

Save space in computer room

Less network hardware needed

Who is involved? Linux and Xen project Microsoft and Virtual PC software VMWARE and multiple software systems Apple has virtualization built into OSX Leopard Sun systems

Where is industry heading? Future server buying trends are forecasting virtualization will reduce need Green IT is becoming a hot issue The ability to perform constantly more with same hardware suits virtualization

Virtual Applications Install an application in a protected space with its own installation files and registry Allows multiple version of the same application to run side by side Test applications and remove them cleanly No more bloated registry and DLL hell Remotely deploy new applications very fast Applications available can be related to Group membership

Thin Clients Very quick to start Can be run locally or remotely Thin clients are secure, only use minimal power and do not need upgrading Centralise all storage requirements Only screen, mouse and keyboard changes on the network

Very quick to start

Can be run locally or remotely

Thin clients are secure, only use minimal power and do not need upgrading

Centralise all storage requirements

Only screen, mouse and keyboard changes on the network

Thin Client Example Run 20-40 thin clients per server Full multimedia thin clients available Can use wireless, Ethernet, modem or 3G card for connection Can also be used for VOIP telephony Use VPN connections
