Brightside Media's marketing demand spikes sharply during two months each year, and its current servers are idle for most of the rest. The finance director favours moving the workload to a public IaaS provider. Which benefit most directly supports this proposal?

The key benefit is elasticity: Brightside can scale capacity up for the two peak months and down afterwards, paying only for usage rather than investing in servers that sit idle most of the year. Cost savings, security and independence from the provider are not guaranteed.

  1. AElasticity, allowing capacity to be scaled up and down with pay-for-use charging instead of fixed capital investment in peak capacityCorrect
  2. BElimination of all security responsibilities for the company
  3. CGuaranteed lower total cost in every year regardless of usage
  4. DComplete freedom from dependence on the provider

Explanation

Public IaaS lets a firm scale resources to match demand and pay for what it uses, converting capital expenditure into operating expenditure. Costs are not guaranteed to be lower every year, security responsibilities remain for the customer's systems and data, and some provider dependence always exists.
