Virtualization Changes
Virtually Everything
Virtualization Stages
Virtualization 1.0 = Consolidation
(cost savings)
Virtualization 2.0 =
Agility
(speed)
Virtualization 3.0 =
Alternate sourcing
(cloud computing)
Cloud computing is also the model for enterprise internal
computing
Key Issues
1.
How will virtualization change IT and business?

Business Process Providers Software Providers
Storage Providers Processing Providers
Service Brokers
The providers in the cloud create a supply
chain — from business process services to component
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
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
Virtualization Changes the
x86 Server Architecture and Market
VMs Making a Mark
• The VM installed base was 2.9M in 2007 — about 7% of the opportunity.
Multicore
• Synergistic with virtual machines.
Server Size
• Virtualization enables larger servers.
Servers More Commoditized
• No lock-in with workloads, and blades more attractive.
Predictions
• The installed base of VMs will grow more than tenfold between 2007 and 2011.
• One out of every four x86 workloads deployed or redeployed during 2008 will be installed in virtual machines.
Virtualization Changes Client Computing:
"Bubbles," Streaming and Letting Go
Emerging Client
• Multidevice, mobile
• Remotely hosted (terminal services)
• Remotely hosted (virtual desktops)
• Nonenterprise-owned
• "Bubbles" (virtual machines)
• Streamed applications
• Software as a service
Traditional Client
• Standard PC
• Enterprise-owned
Software Appliances:
A New Software Paradigm
•
VM packaging enables prepackaged
solutions
•
Virtual software packages (VSPs)
•
Software-based appliances (SBAs)
•
VM operational and service information
(e.g., OVF)
•
Can be managed, updated remotely (by
provider) – enabling on-premise SaaS
•
Can be dynamically moved – from user
to/from provider, between providers
Do Operating Systems Matter?
The Emergence of the Meta OS
An automation layer that governs the usage of distributed
resources
A
service governor
manages the usage of distributed
computing resources at a
service level.
Service Governor
A meta operating system is a virtualization layer between applications and distributed computing resources; it utilizes distributed computing resources to perform scheduling, loading, initiating, supervising applications and error handling.

Virtualization Breaks Traditional
Software Pricing and Licensing Models
Fractional use, consolidated
• Especially when consolidated to large servers • Multicore trend exacerbating issue
Dynamic change
• Old friction: Deployments, upgrades are rare
• Now: Deployments are fast, resource allocations change quickly
Dynamic movement
• Old paradigm: Tie software to serial numbers • Now: Workloads can move dynamically between
servers
Virtual machine packaging
• Software-based appliances, pre-integrated software

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
IT run as a business
Cloud Impact?
Paying per usage is a
fundamental
characteristic of cloud
computing –
Operationalizing Virtualization:
New Approaches, New Concerns
Configuration
• Virtual resources vs. software
• Managing asset location
• Managing dependencies
• Virtual machines as black boxes — e.g., appliances
Problem
• Matching problems to moving assets
• Additional moving and changing parts
Change
• Ease/speed of virtual machine creation
• New virtual changes
• V-to-P and P-to-V as a new step
Chargeback
• Capex mapping to virtual deployments
• Dynamic usage challenges
• Different physical hosts change metrics
Security
• New privileged layer of software that will be targeted
• Separation of admin. duties
• Protecting and patching offline virtual machines
• Auditing virtual machine movement, changes and life cycles is inadequate
• Immature security and mgmt. tools
Performance/Capacity
• Shift to holistic capacity planning
• Virtualization vs. service-level agreement mgmt.
Virtualization Completely
Scrambles the Market
Technology virtualization and abstraction layers are also eliminating market boundaries and creating new market opportunities.
Servers
• Better utilization = less capacity sold (now)
• Agility = more sold (later) • Sell as a service?
Networking
• The network is the computer — but everyone is managing
the network
Storage
• Server virtualization challenging storage virtualization role • Sell as a service?Applications
• Packaged software, and/or SaaS? • Package as appliances?
• Pricing and licensing changes • Cloud: Opportunity or threat?
Outsourcing
• From process and best practices to economies of scale and agility
• Prospects can create their own economies of scale
Management
• From monitoring and
components to active service management
Operating Systems
• ―Just‖ a container?

Primary Considerations:
VMware vs. Microsoft
Capabilities and Management
VMware is 2-3 years ahead of Microsoft in virtualization
functionality, including Vmotion, DRS, HA, SRM;
Microsoft offers mainstream System Center for physical
and software management tools that VMware lacks
Stability
VMware’s architecture is much more lightweight (32 MB
footprint); Hyper-V leverages a Windows Server subset
(1.5 GB footprint) – a larger system to manage
Maturity
90% of the installed VMs are VMware, with more than
100,000 customers over seven years; Microsoft’s
Hyper-V needs proven deployments
Price
Combined with management tools, typical VMware
pricing is three times higher; however, higher VM density
and increased functionality reduces the pricing gap
The Future of Xen-Based Solutions
Future requires an acquisition or strong alliances.
Possible wild card – but attention to software business ongoing issue. Shift in focus from Xen
toward OS-centric KVM virtualization.
Strongest third player – but challenged to find a server market niche.
Virtualization
management limited — could expand (PlateSpin recently acquired).
Clearly focused on
defending Oracle stack — but how rich will their management be?
But consider…
The x86 server market is less than 10%
penetrated, there are many submarkets, the
Best Practices:
Starting to Virtualize Servers
Start small, but think big
Require rapid ROI - but
look beyond cost savings
Define your storage
strategy first
Virtualize the right
applications
