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
