What is a common advantage of using a public cloud?

  1. Owners have physical control over resources

  2. Pay only for what is used

  3. Requires specialized personnel

  4. Always requires a long-term commitment

The correct answer is: Pay only for what is used

The advantage of using a public cloud that stands out is the pay-as-you-go model, which allows organizations to only pay for the resources they actually use. This flexibility enables businesses to scale their operations without the financial burden of investing in expensive infrastructure that may not be fully utilized. It can optimize costs, as companies can adjust their spending based on varying demands, such as increased usage during peak times or reducing resources during slower periods. This model is particularly beneficial for startups and small businesses that may have fluctuating workloads. Utilizing a public cloud minimizes the need for long-term commitments or upfront capital expenditure, making cloud services accessible and economical for various organizations, regardless of their size. This contrasts with options that imply ownership and resource control, which typically require physical infrastructure and potentially lead to higher operational costs.
