1.1 Describe cloud computing
1.A startup company wants to launch a new application immediately without spending money on upfront hardware costs. They want to pay only for the resources they use on a minute-by-minute basis. Which cloud computing model and expenditure type fits this requirement?
- A.Private Cloud and Capital Expenditure (CapEx)
- B.Public Cloud and Operational Expenditure (OpEx)
- C.Hybrid Cloud and Capital Expenditure (CapEx)
- D.Private Cloud and Operational Expenditure (OpEx)
Show answer & explanation
Correct answer: B — Public Cloud and Operational Expenditure (OpEx)
- A. Incorrect. A private cloud involves dedicated infrastructure for a single organization, which typically requires a significant upfront Capital Expenditure (CapEx) to purchase hardware. This is the opposite of the startup's requirement to avoid upfront costs.
- B. Correct. A public cloud provides on-demand, shared infrastructure managed by a cloud provider. This allows a company to launch immediately without buying hardware. This aligns perfectly with the Operational Expenditure (OpEx) model, where you pay only for the resources you consume (pay-as-you-go), which matches the startup's requirements.
- C. Incorrect. A hybrid cloud combines public and private clouds. The private cloud component would still require an upfront Capital Expenditure (CapEx) for hardware, which contradicts the startup's goal of avoiding initial spending.
- D. Incorrect. While the Operational Expenditure (OpEx) model is desired, a private cloud is the wrong model. A private cloud is fundamentally based on dedicated infrastructure that requires an upfront capital investment, even if ongoing management costs are operational. Therefore, it does not meet the requirement to avoid initial hardware costs.
