BILLING – METERED CHARGES BASED ON USABILITY

Cloud Model:

• Pay-as-you-go model

• No annual contract

• No commitment for a specific level of consumption

• Allocation of resources as needed

• Pay on hourly basis

• Many economic advantages benefits while running applications for

IT organizations

• No/less need for entrepreneurs to raise initial capital

• Utilization of compute resources for pennies per hour

• Playing field changer allowing the little guy an equal footing with

large corporations
