Dana Clark is the CIO of a regional auto insurance company in the Midwest. She has been asked to slash her IT budget by 20 percent, in an unprecedented austerity move by the company. Currently the company has local offices in 20 locations around a five-state area. Each of these offices houses an office manager, an IT person, a dozen insurance agents, and their clerical support. The home office, located in Ames, Iowa, contains a similar contingent of employees with the addition of accounting, payroll, and HR staff, as well as the executive suite and their support staff. Dana has made the decision that the optimal way to reduce her budget in this substantial fashion is to convert the network to a virtualized environment.
