2. 1. Early days for virtualisation Virtualization Adoption x86 servers used for virtualization Virtualization adoption continues to rise: % of x86 servers virtualized expected to grow to about 14% in 2010 Source: IDC Sep 2006

3. 2. New entrants – more choices

4. Server Virtualization Application Virtualization Desktop Virtualization Presentation Virtualization Management Virtualization from the data center to the desktop Assets – both virtual and physical – are managed from a single platform 3. Range of types of virtualisation Profile Virtualization

5. Server Virtualization Application Virtualization Desktop Virtualization Presentation Virtualization Management A comprehensive set of virtualization products, from the data center to the desktop Assets – both virtual and physical – are managed from a single platform Microsoft Virtualization Products Microsoft Hyper-V ® Server Data Virtualization Windows Vista Centralized Desktop Folder Redirection Offline files

6. 2.Integrate the management of virtual servers with physical servers, 3.Keep same disciplines of security, continuity and recovery to maximise business availability 4.Drive the necessary cultural changes for effectively managing resources in a virtual environment 1.Virtualisation as part of IT infrastructure 4. Successful virtualisation

7. 5. Benefits? 24 October, 2015 Optimize utilisation of servers Reduce costs: hardware, power, space Reduce overall system complexity Reduce application compatibility conflicts Control costs Disaster recovery capabilities Streamline server maintenance, and isolate risk Enable access to any desktop application anywhere Improve Availability Dynamic resource allocation Faster provisioning of services / workloads to support business growth and meet SLAs Drive Agility

8. 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

10. 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 24 October, 2015 Warwickshire County Council

11. Why is virtualisation <10%? Cost Complexity Management Virtual Sprawl Single Point of Failure Software Licensing Hardware Performance Political Security Concerns

12. 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
