(TheGuardian) What is it? Infrastructure cost savings/ avoidance from moving to the cloud What is it? Efficiency improvement by function on a task-by- task basis What is it? Benefit of improving SLAs and reducing unplanned outage What is it? Deploying new features/ applications faster and reducing errors Cost impact Value impact Typical Focus Most compelling Cloud benefits Cloud Value Framework
