3 Application Virtualization Timeline Percent Virtualized 100% virtualized Utilities Tier-2 Tier-1 Scalability Performance Availability Agility Manageability Consolidation Time 2011 Enterprise Strategy Group 3 59% have not virtualized any tier-1 workloads

4 ESG Server Virtualization Maturity Model Percent of current virtualization users, by segment Basic, 22% Progressing, 53% Advanced, 25% 75% of the market 58% are less than 30% virtualized 75% expect to be more than 30% virtualized in 24 months 56% have less than 250 virtual machines deployed 2011 Enterprise Strategy Group 4

5 Factors Preventing Organizations from Using Virtualization Collaboration and Training Best Practices Virtual Stall Application Performance Lack of Understanding Virtualization technology is not the barrier to success 2011 Enterprise Strategy Group 5

6 Accelerating Virtualization Adoption Massive Opportunity 70% of organizations using more than one hypervisor 31% expect 25:1 VM consolidation in 24 months 75% expect to be more than 30% virtualized in 24 months Key Metrics for Gauging Virtualization Success 2011 Enterprise Strategy Group 6

7 Extent of Production VM-based Applications Tier-2 database (i.e., Oracle Standard, Microsoft SQL, MySQL, etc.) Why This Matters Deployment flexibility Simplified administration Reduced hardware costs Ability to improve service levels 2011 Enterprise Strategy Group 7

18 2011 SQL Server Results Summary Hyper-V R2 SQL Server 2008 R2 Workload Scalability 20,000 to 80,000 customers (one to four VMs) Low response times as VMs are added Near linear performance scalability Transactions SQL server batch requests per second Low Hyper-V R2 overhead compared to physical (12%) 2011 Enterprise Strategy Group 18

19 The Bigger Truth Why This Matters Performance scaled with low response times as SQL Server application workloads were consolidated on a physical server. The manageably low performance impact of Hyper-V R2 won t be detected by the vast majority of end-users and applications. The performance, scalability, and low overhead of Hyper-V R2 can be used to reduce costs and improve the manageability, flexibility, and availability of consolidated SQL Server applications Enterprise Strategy Group 19

20 Issues to Consider Mileage varies; test with your workloads and your data Hyper-V Included for free with Windows Server 2008 Proven to perform with demanding applications Size matters Utility-class SQL Server apps are a great place to start Apps that are resource-constrained on a physical server may not be good candidates for virtualization High Availability matters Leverage ESG Lab Validations, Microsoft and its partners best practices/proof points 2011 Enterprise Strategy Group 20
