Virtualization With VMware or Hyper-V: What You Need To Know
Tom BittmanGartner Webinar25 November, 2009
Server Virtualization Myths
Myth: Virtualization is a commodityFact: Virtual infrastructure technologies drive management
technologies that drive private cloud architectures that determine cloud computing strategies
Myth: It's already commonFact: 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 more focused on ease of use, packaging, DR.
Key Issues
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?
IT virtualization is the abstraction of IT resources in a way that masks the physical nature and boundaries of those resources from resource users.

• 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 2010

x86 Server VirtualizationMarket Landscape
• 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
• Focused on KVM virtualization (RHEL-based)
• Inclusion with Windows, SCOM management synergy
• Popular for Windows-only environments –mainly SMB
• Promoting heterogeneity
• Successful niche with Virtuozzo containers, especially with Linux and service providers
• Market and technology leader
• Promoting private clouds and cloud migration
• Expanding virtualization management capabilities – moving up the stack
Coming Soon:Magic Quadrant
• Leading provider of Xen-based virtualization
• Strategy includes managing Hyper-V
• Success with existing Citrix customers, opportunity with service providers, mixed and Linux enterprises
VMware or Microsoft?By 2012, at least 25% of the virtual machine installed base
in enterprises will be Microsoft Hyper-V.
Reasons to choose Microsoft:• Smaller deployment (<100 VMs)• Server virtualization is primarily
being used for less-critical servers• Exclusively or primarily using
Windows operating system• Heavy user of Microsoft
management (Systems Center)• Low cost more important than
features• Simplicity in managing a mixed
physical server and virtual server environment important
Reasons to choose VMware:• Existing investment in VMware
skills, technology, automation• Large deployment (>200 VMs)• Low tolerance for downtime• Requirement for high density
of VMs per server• Mix of server operating systems• Maturity and features more
important than low cost• Building a VMware-centric private
cloud infrastructure and the vCloud initiative are attractive

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

Best Practices: Starting to Virtualize Servers
Start small
Be application smart
Require rapid ROI
But think agility
Butthink big
Pool well
Operationalizing Virtualization: Mind Your Porridge!
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
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
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
• 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
Securing Virtual Servers: Issues and Possibilities
IssuesVirtualization introduces new “platform” that must be included in patch, configuration and vulnerability managementOffline VMs need to be kept up-to-date and protectedEarly virtual switches are not visible to traditional network-based securityVMs will become mobile –security policies that are not mobile (e.g., tied to IP or MAC addresses) are broken
PossibilitiesSecurity appliances shifting from physical and proprietary to virtualVM state inspection becomes a new security opportunity, without agents in the virtual machinesSecurity decoupled from workloads requires security metadata, enables adaptability –including to the cloud
Virtualization Is a Modernization Catalyst and Unlocks Cloud Computing
Attributes of Cloud Computing

• Abstracts implementation from users
• Forces service-level discussion• Technology hoster becoming
service provider
• Enables faster delivery and resource changes
• Enables hardware sharing• Enables economies of scale
• Software pricing and licensing models broken – some kind of usage-based model needed
• Usage tracking and chargeback to manage usage

Action Plans
CIOs and I&O leaders should …• Now
- If you haven't started virtualizing, it's time to start, and you havea 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, consider an upgrade to R2- If you are a VMware customer, consider an upgrade to vSphere 4.0
• Your Next 12 Months- Develop a cloud strategy and ensure your
virtualization plans match
