  • IResources are distributed as a service
  • Allows for dynamic scaling
  • Has a variable cost, utility pricing model
  • Generally includes multiple users on a single piece of hardware
Where IaaS Makes Sense
  • Where demand is very volatile – any time there are significant
    spikes and troughs in terms of demand on the infrastructure
  • For new organizations without the capital to invest in hardware
  • Where the organization is growing rapidly and scaling hardware
    would be problematic
  • Where there is pressure on the organization to limit capital
    expenditure and to move to operating expenditure
  • For specific line of business, trial or temporary
    infrastructural needs
Where IaaS May Not be the Best Option

  • Where regulatory compliance makes the offshoring or outsourcing of data storage
    and processing difficult
  • Where the highest levels of performance are required, and on-premise or
    dedicated hosted infrastructure has the capacity to meet the organization’s needs
