Explanation
Correct Answers: A and D
Why A is correct:
- AWS replaces the traditional capital expenditure (CapEx) model with operational expenditure (OpEx) through pay-as-you-go pricing
- This eliminates large upfront investments in hardware and infrastructure
- Organizations only pay for what they actually use
Why D is correct:
- AWS benefits from massive economies of scale due to serving millions of customers globally
- These economies of scale allow AWS to continually reduce prices for customers
- AWS has reduced prices over 100 times since its inception
Why other options are incorrect:
- B: While AWS offers high availability, it doesn't eliminate all user downtime - applications still need proper architecture for high availability
- C: AWS doesn't eliminate the need for IT staff - organizations still need cloud engineers, architects, and administrators
- E: AWS offers multiple pricing models for EC2 (On-Demand, Reserved Instances, Spot Instances, Savings Plans), not a single pricing model
