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

Compounding Issue -- Virtualization SkillsDo you believe you have sufficient skills in your enterprise

today to manage your virtualized systems?
