Which of the following is a key characteristic of IaaS?

  1. Managed software services

  2. Scalable network bandwidth resources

  3. Application hosting only

  4. Virtual machine management only

The correct answer is: Scalable network bandwidth resources

IaaS, or Infrastructure as a Service, is a cloud computing service model that provides virtualized computing resources over the internet. One of its key characteristics is the provision of scalable network bandwidth resources. This means that organizations can adjust their resources dynamically to meet fluctuating demands without the need to invest in physical hardware. This scalability allows businesses to accommodate increases in workload, traffic, or application usage seamlessly. In the context of IaaS, users can scale up or down based on their needs, which is particularly beneficial for businesses experiencing variable demands or for those looking to optimize costs as they only pay for the bandwidth and storage they actually use. This flexibility and efficiency is a hallmark of the IaaS model, distinguishing it from other services that may not offer the same level of scalability in their resources.
