1. Early days for virtualisationVirtualization Adoptionx86 servers used for virtualization
Virtualization adoption continues to rise: % of x86 servers virtualized expected to grow to about 14% in 2010

Virtualization and Green IT?
• Environmental Impact
• Energy costs to go over 50 % of the total IT budget for a typical data center
• Daily power consumption of a typical datacenter = monthly power consumption of thousands of homes
• 61 billion kilowatt hours going toward data centre energy consumption
• 10-15 more power plants needed by 2011 to keep up with data centre power consumption
• x86 hardware consumes ~80% of the normal workload power even when idle
• Virtualization Promise
Virtualization can reduce energy usage by 90%
Virtualizing 100 servers eliminates estimated 500K lb CO2 (annual emissions)
95% or over 30M servers are still to be virtualized

What are customers doing?
• 85% reduction in server hardware requirement
• “Using System Center Virtual Machine Manager 2008, we’ve been able to reduce new-server provisioning time from 16 hours to about 3 minutes.”
• Reduced data center costs, repurposed power capacity to install a larger storage area network, and improved disaster readiness.
• New commodity services through faster provisioning
• Faster simpler deployment of applications, increased innovation in use of new applications

Why is virtualisation <10%?
• Cost• Complexity• Management• Virtual Sprawl• Single Point of Failure• Software Licensing• Hardware• Performance• Political• Security Concerns
Securing the Virtual Environment
What’s the Same What’s Different• Deploying and configuring
security technologies
• Protecting against complex attacks
• Enabling secure access to assets based on policy
• Managing identities and their rights
• Ensuring software remains up-to-date
• Visibility into security state
• Responding to and remediating security issues
• Securing the virtualization layer– trusted platform for virtual machines to run
• Attack surface– If hypervisor compromised, denial of service
or compromise possible to multiple virtual machines sessions
• Increased risk from concentration of assets on physical devices
• Isolating virtual machines from each other
– Minimizing the impact of the compromise of an operating system inside a virtual machine
• Monitoring VM to VM traffic
– Only enabling communication where policies can be enforced and traffic analyzed
Consolidation of servers = consolidation of trust
