Virtualisation Overview
What is Virtualisation? Why is it the most important trend in
IT infrastructure? Technology 101
What is Virtualisation? A way to loosely couple “workload” to “hardware” by
Making all devices look the same Reduces diversity and simplifies the environment Enables change, i.e., applications, or data, can be moved around
Making a single server look like many servers While still providing robust isolation and resource control Enables consolidation which increases hardware utilisation and lower TCO
Making many storage units look like a single unit Hides storage complexity, simplifying storage management Enables policy based storage management
Today it is all things to all vendors, beware!
Server virtualization & consolidation are CIO’s #1 & #2 priorities - Goldman Sachs Survey
Why Is It So Important? It is the most important infrastructure
trend in the last 7 years & the next 7 Totally changes IT infrastructure
Today it enables capabilities that support business needs affordable
HA, DR, CO, CoD, rapid provisioning All on commodity hardware
By 2015 commodity infrastructure becomes a unified system
Remarkably like the old M/F Resources managed by policy to SLAs Virtualisation is the data centre O/S
By 2015 You Will Buy A “Datacenter in a Box”. Virtualisation Is Essential To Harness the Power

Technology 101 Server Virtualisation
Already mainstream Hypervisor now free
Storage Virtualisation Some benefits but take caution
Virtual Desktop (VDI) Probably just a niche like Citrix
Application Virtualisation The next important desktop
enablerThe Hypervisor Is A Commodity And The Management Tools Are The Differentiators
Vendor & Technology Landscape
Who Are The Market Leaders? Separating The Facts From The Hype
Who Are The Market Leaders?
Server Virtualisation (IDC) ’07: 35% of new servers virtualised
Implies 90% of all new workloads! Projecting 52% in ‘08
50% of firms using it now. 90%+ in the next 18 months.
App-V &ThinApp emerging in App Virtualisation market
Citrix still strong in Display Virtualisation
Many challenges in moving beyond this
How Does Microsoft Entry Change The Market?
Separating The Facts From The Hype
Virtualisation is the hot buzz word, BEWARE of vendors product hype!!! Server Virtualisation – VMware is mature and ready for use
VMware is the clear leader, most organisations should use this strategically Now the hypervisor is free, MS’s major advantage has been neutralised
MS will struggle to displace VMware Technically inferior, 18month to 3 years behind. Will try to change the goal posts to dynamic IT. Not achievable for most
Open source is not the answer either Xen is probably defunct KVM will be the open source choice
Storage - Thin provisioning is the next key storage virtualisation Network based virtualisation has limited traction IP storage will grow rapidly, especially in a Virtualised environment
Virtual Desktop (VDI) - beware vendor hype Many small pilots but very few in production (1 or 2 in Australia) Cost benefits do not stack up, move to stateless PC architecture instead
What You Must Know
The benefits The questions you need to ask
The Benefits
Lower TCO Simple, low cost HA and DR Rapid provisioning Continuous operations Capacity on Demand
The Questions To Ask Is my application suitable?
If not why not? Challenge the status quo? Push back on vendors! What are the savings, benefits and risks from using it?
Look for lower, shared server costs, affordable HA & DR, agility What can I do now that I could not afford before?
More quickly provide new services/applications Do we have the skills? How will operations change?
Where can I source these skills. Can I use consultant to build & transfer?
How does this impact my outsourcer? Do they provide it? What is their cost model? Is it flexible?
How does this new infrastructure get funded?
