Virtualization Benefits

Abstracts applications and services from physicalservers: Groups multiple applications and services onto a single

physical host Breaks the 1:1 relationship between

applications/services and physical servers

Retains isolation

Increases agility Reduces hardware support and lifecycle issues

Simplifies migration

Business Case: Perceptions

Managing expectation/perceptions

Loss of flexibility

Lack of responsiveness Diminished security

Degraded performance

Loss of control

Identify specific concerns of each Business

Unit

Business Case: Cost

Parity with Physical server billing model

Cost of a VM is much less than a physical

server Hardware

Support

Transparent billing Consistent format

Regularly validated
