Top 5 Critical Drivers for Virtualization Top 5 Drivers for Deploying Virtualization
Not Only In Test And Development
• Test and development is the leading use case (79% of enterprises)
• Increasingly a production technology
• 75% deploy for production app
• 50% deploy for production Db/web servers
• Fundamental for mission-critical services
• Deployments for all workloads have increased since 2006

Multiple Layers Of Complexity, Multiple Problems
Key Concerns for Virtual Systems Management
(VSM)
Key VSM Concern -- Managing VM Sprawl• Uncontrolled VM deployment
and migration results in:
• Increased management
requirements
• Software compliance issues
• Best practice compliance
issues
• Configuration management
problems
• Security and risk exposure
• Uncontrolled cost
• Service and performance
problems
Enterprises must automate and Enterprises must automate and control virtual machine lifecycle control virtual machine lifecycle
processes to prevent these processes to prevent these exposuresexposures
Key VSM Concern -- Managing Process• Coordination
• Maintaining configuration, patch cycles,
availability
• Connecting dynamic VM environment with
existing processes, procedures
• Compatibility
• Of human and process interfaces, inputs, outputs
• Of skill sets and other human issues
• Of integration and orchestration technologies
• Of management tools
• Of versions and releases
Source: Enterprise Management Associates
Key VSM Concern -- Security, Audit, Control
• 41% cited “Improve Security and
Control” as a critical driver
• Only 31% cited Security and Control as
an effective outcome
• Security Administration is the #1
discipline that gets harder in a virtual
environment
• Complexity increases risk and security
issuesSource: “Virtualization and Management: Trends, Forecasts, and Recommendations”, Enterprise
Management Associates, 2008
Other VSM Concerns
• Abstraction and Visualization
• Managing the Rate of Change
• Dealing with Complexity
• Ensuring Consistency
• Governance and Risk Management
• Containing Costs
• Providing Support
• People and Human Issues
• ManageabilityVirtualization is not a silver Virtualization is not a silver
bullet -- how well you manage bullet -- how well you manage it is a critical success factorit is a critical success factor
Compounding Issue -- Virtualization SkillsDo you believe you have sufficient skills in your enterprise
today to manage your virtualized systems?
