2 Virtualization Myths Myth: It's already common. Fact: Only approximately 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.

3 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 virtualization? 2. How should users select, deploy and manage server virtualization technologies? 3. How will virtualization technology evolve?

4 Virtualizing the Data Center: From Silos to Clouds Sprawled ponent-orientation Virtualized Layer-Orientation Cloudenabled Automated Service-Orientation Policies Optimization 2002 Hardware costs down, flexibility up 2002 to 2012 Service levels and agility up Provisioning Workloads Data Resources Identities Services 2010 to 2020 Availability

5 Virtual Machines: Moving From Niche to Mainstream Large enterprises started sooner Global 500 (G500) are perhaps 25% virtualized Small or midsize 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 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 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 Parallels Containers, especially with Linux 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

(n=106) None 4% Citrix 1% Others 8% Other combination 8% Microsoft 1% VMware and Microsoft 10% Other combination 23% Which virtual machine solution will you be using for x86 servers in 2010? (n=123) Citrix 4% Others 8% Microsoft 6% VMware and Microsoft 40% VMware 69% VMware 19%

9 Best Practice: Assert Which Workloads Not to Virtualize Virtualization changes server architecture and redefines all infrastructure. Which workloads not to virtualize to date Process constraints: Real-time applications time stamp and abstraction don't mix. Transactional constraints: I/O-intensive requires more hardware assistance initially, with direct-path I/O (for throughput) and eventually multipath I/O (for concurrency). Commercial and support constraints: Licensing, support and break/fix require parallel universes for production and testing/development. Check your constraints today: Easier done in test/development than

10 Best Practice: Pool Capacity Effectively Consolidate Dynamically Density average: Six VMs per socket (and growing) Separate static VMs from dynamic Don't overanalyze Real time Modernized applications Databases High concurrency High I/O and Manage Pools Common service levels Workload affinity Within business units Sharing excess ERP Terminal services App../Java EE BI tools High use High bandwidth Load testing File/print Directory Gateways/ controllers Web/Java EE Pub. folders/ OWA/LCS Portals Low use Reporting/ doc. servers

12 Software Appliances: A New Software Paradigm A pure software appliance is a software-only solution that delivers predefined services through an application-specific interface, with no accessible operating software. App OS VMs enable prepackaged solutions Virtual software packages (VSPs) Software-based appliances (SBAs) Attached operational/sla metadata Including relationships to other appliances (OVF) On-premises SaaS Managed, updated by provider remotely Dynamically sourced Enabling full (off-premises) SaaS, movement between providers, movement back to customer

13 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 (such as tied to IP or 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

14 Virtualization Changes Client Computing: "Bubbles," Streaming and Letting Go Emerging Client Traditional Client Standard PC Enterprise-owned Corporate image and installed applications Multidevice, mobile Remotely hosted (terminal services) Remotely hosted (virtual desktops) Non-enterprise-owned "Bubbles" (virtual machines) Streamed applications Software as a service

15 Virtualization Enables Storage Mobility and Potentially Improved Use Quality of Service Enabling capacity redeployment Increasing performance by striping and caching, avoiding hot spindles Providing easier and less-impactful migration Consolidation = lower staffing costs Planning From good requirements planning to reacting to usage From time-consuming reconfiguring to virtual reallocation Flexibility, Agility, Growth Provisioning Recovery Physical limits don't constrain Dynamic volume change Many Managed as One Abstraction Managing physical storage can be isolated to focused administrators Storage users need not be storage-savvy Caution: Virtualized storage management is more-complex One Used as Many

16 Virtualization Enables and Motivates Chargeback From Fixed to Variable Usage Virtualization enables a move to utility pricing Most businesses are not prepared to deal with IT as a variable expense Tools and measurement standards needed The Danger of a Frictionless Model Old - Capex requirement - Time to respond to requests New - Capex asynchronous, smaller - Rapid response (30x faster) Chargeback helps provide the friction helps Cloud Impact? Paying per usage is a fundamental characteristic of cloud computing organizations that embrace chargeback are better prepared for cloud computing.

17 Virtualization Changes Business And Prepares for Cloud Services Replace Equipment Sharing Defining service needs Agility Low barrier to entry Faster deployments Rapid reaction to change Funding From project- to usage-based From consolidated to user Sourcing Rapid expansion of alternative delivery models Dynamic, granular Can the business define service requirements? Is the business ready for speed? Does the business want variable IT costs? Can the business choose the delivery model?

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

19 Action Plans CIOs and I&O leaders 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 - 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
