One of the revolutions that the Cloud has ushered in is ‘pay per use’ and small and medium sized enterprises benefit enormously from this model. This means only paying for what we actually consume and use. In a traditional architecture model, users used to pay for a fixed package of IT resources, even if they only used a reduced percentage of its capacity.
This ability was not possible in a traditional model, based on predicted use and consumption, as one had to analyse needs carefully, and negotiate the best deal on capacity before hiring a service and then seek to achieve ROI on the total cost. Such a process is more agile with Cloud servers as the ‘capital expenditure’ (CAPEX) is changing into ‘operational expenditure’ (OPEX). As a result, infrastructure costs can now stay totally transparent and administrators remain in full control of any costs incurred, backed by billing that provides full clarity regarding the investment in resources that each project requires.
