4 Server Virtualization Myths Myth: It's already common Fact: Only about 16% of workloads are running in virtual machines today about half by YE2012; the fastest growing market today is small business Myth: It's primarily about saving money Fact: Large enterprises virtualized to save money, but later surveys show that the key is agility; small enterprises never consider saving money the primary reason to virtualize Myth: Virtualization is a commodity Fact: Virtual infrastructure technologies drive management technologies that drive private cloud architectures that determine cloud computing strategies

5 Key Issues IT virtualization is the abstraction of IT resources in a way that masks the physical nature and boundaries of those resources from resource users. 1. How is the market adopting server virtualization? 2. How should users select, deploy and manage server virtualization technologies? 3. How will server virtualization technology evolve?

6 Virtual Machines: Moving from Niche to Mainstream Large enterprises started sooner global 500 (G500) are perhaps 25% virtualized Small-to-midsized businesses (SMBs) started later, and tend to be less virtualized SMBs are virtualizing very fast will exceed G500 penetration in 2009 or % 50% 40% 30% 20% 10% 0% 2% Percentage of Installed x86 Workloads Running in a VM 4% 7% 12% 19% 28% 38% 48%

7 Server Virtualization in Small to Midsized Businesses Q. Has your organization started to invest in virtualization or does it plan to invest in virtualization during 2009? Q. To what extent is x86 server virtualization implementation a priority for your organization in 2009? 100% 80% 60% 40% 20% 0% U.K. U.S. Australia Germany France Brazil India Russia China No Plans Starting in 2009 Started before % 80% 60% 40% 20% 0% Australia Germany U.K. U.S. Russia China France India Brazil Low priority Medium priority High priority 2009 survey of 1394 companies with employees (roughly equal number of companies per country)

8 Virtual Machine Installed Base and Growth Projections The installed base of virtual machines will grow 10X in four years Virtual Iron Citrix 1% 2% Others Microsoft 1% 8% Microsoft 27% Citrix 6% Red Hat 2% Others <1% 2008 (5.8M) VMware 89% 2012 (58M) VMware 65%

9 x86 Server Virtualization Market Landscape Market and technology leader Promoting private clouds and cloud migration Expanding virtualization management capabilities moving up the stack Inclusion with Windows, SCOM management synergy Popular for Windowsonly environments mainly SMB Promoting heterogeneity Leading provider of Xenbased virtualization Strategy includes managing Hyper-V Success with existing Citrix customers, opportunity with service providers, mixed and Linux enterprises Coming Soon: Magic Quadrant Successful niche with Virtuozzo containers, especially with Linux and service providers Focused on KVM virtualization (RHELbased) SUSE Linux and Xen Building around PlateSpin for management offering Need alliance? Favors Oracle VM with Oracle software Strength in Oracle stack, but weak market appeal outside

10 Sweet Spots for the Major Virtualization Players Large Enterprise: Largest opportunities addressed today by Citrix and VMware Small Enterprise: The largest opportunities addressed today by Microsoft Service Providers: The largest opportunities addressed today by Citrix, Novell and Red Hat Highdensity, few apps Enterprise Service Provider Large Small Expose VMs Heavy Oracle Heavy Linux Mixed Windows Linux Mixed

11 Major 2009 Industry Announcements Announcement XenServer free Essentials for Xen/Hyper-V Acquired Sun and Virtual Iron vsphere 4.0 and pricing Acquired SpringSource Hyper-V and SCVMM R2 (including live migration) KVM-based rollout (RHEV) late 2009 Parallels Server delivery in late 2009 Advice/Ramifications Momentum Essentials is now key - consider in Linux or mixed environments Use when Oracle is managed separately, and sharing outside Oracle not critical Continues to push boundaries (now I/O performance, etc.), price is only major issue Live migration fills big gap, large single point of failure still concern but not for SMBs Serious alternative, especially for service providers, Linux and mixed environments Not as important or differentiated as Virtuozzo Containers

12 What s Big in VMware vsphere 4.0 and Microsoft Hyper-V/SCVMM R2 I/O performance (direct I/O) Host scalability: 64 cores, 1 TB, 256 VMs VM scalability: 8 cores, 255 GB Thin provisioning, hot disk extend, volume grow Distributed switch Network Vmotion vcenter Host profiles and Orchestrator Manage 300 hosts, 3000 VMs Linked mode manage up to 10,000 VMs Distributed Power Management Fault tolerance VMsafe and vshield Zones Hot add CPU, memory New packaging: Essentials through Enterprise Plus Live migration Processor compatibility (software) Host scalability: 64 cores, 1 TB, 384 VMs VM scalability: 4 cores Clustered Shared Volumes (multiple VMs per LUN) Core parking SCVMM R2 Quick storage migration (2 min) Hot add/remove storage Live migration queuing Host maintenance mode

14 Best Practices: Starting to Virtualize Servers Start small But think big Require rapid ROI But think agility Be application smart Pool well

15 Operationalizing Virtualization: Mind Your Porridge! Too cold and you won t achieve potential savings Too hot and you ll have VM sprawl, cost overruns, breakdowns Be proactive, and plan ahead to be just right Assets/Configuration Don t wallpaper over problems Expect higher demand, more transient usage Manage the speed (approvals, quotas, chargeback, reporting) Don t forget offline assets Dependency management gets harder Descriptive metadata will evolve Be strategic cloudsourcing is coming Performance/Capacity Merging: Incremental, asynchronous capacity changes Shift to holistic capacity planning VM placement important but don t over-analyze, or over-optimize Beware of VM performance overhead, and VM resource competition Descriptive metadata will evolve Funding/Chargeback Virtualization<> free From project-based to usage-based a synchronous asset buying Account for all usage, expose simplicity (less dynamic, less detail, more predictable) Build metrics that are not dependent on physical hosts and lead to external cloud alternatives

16 Securing Virtual Servers: Issues and Possibilities Issues Virtualization introduces new platform that must be included in patch, configuration and vulnerability management Offline VMs need to be kept up-to-date and protected Early virtual switches are not visible to traditional networkbased security VMs will become mobile security policies that are not mobile (e.g., tied to IP or MAC addresses) are broken Possibilities Security appliances shifting from physical and proprietary to virtual VM state inspection becomes a new security opportunity, without agents in the virtual machines Security decoupled from workloads requires security metadata, enables adaptability including to the cloud

17 Virtualization Is a Modernization Catalyst and Unlocks Cloud Computing Enables Economies of Scale Technology that enables sharing Decouples IT from Users Enables service-oriented shift Enables alternate sourcing Culture change Speed and Elasticity Low barrier to entry Faster deployments Rapid reaction to change Breaks Software Pricing and Licensing Fractional use, consolidated Dynamic change and movement Vendors realize just don't want to be first Enables and Motivates Chargeback From fixed to variable use Danger of frictionless computing

18 Virtualization Leads Inexorably to Cloud Computing Stage 1: Server Virtualization Stage 2: Distributed Virtualization Stage 3: Private Cloud Stage 4: Hybrid Cloud Hardware efficiency Capital cost Deployment speed Flexibility Automation Operational cost Reduced downtime Self-service Service standardization IT as a business Usage-based pricing Capital and operational cost Low barrier to entry Total usage flexibility

20 Action Plans CIOs and IT operations should Now - If you haven t started virtualizing, it s time to start, and you have a number of alternatives - If you have virtualized, perform a health check on your processes, management and security Your Next 90 Days - Develop a private cloud strategy, and ensure your virtualization plans match - If you are a Hyper-V customer, upgrade to R2 - If you are a VMware customer, upgrade to vsphere 4.0 Your Next 12 Months - Develop a cloud strategy, and ensure your virtualization plans match
