- A
Pay-as-you-go pricing model
- B
High availability across multiple regions
- C
Automated scalability with Auto Scaling
- D
Dedicated physical servers for workloads
Show answer and explanation
Correct answer: A
Explanation
AWS's pay-as-you-go pricing model is central to the concept of cloud economics. It eliminates the need for large capital expenditures, allowing businesses to pay only for what they use. This flexibility and cost predictability make it a key driver of cost savings when transitioning from on-premises infrastructure to the cloud.
- A. Correct.
The pay-as-you-go pricing model allows customers to pay only for the resources they use, avoiding upfront capital expenses and reducing overall costs. This directly aligns with the goal of cost-saving.
- B. Incorrect.
High availability ensures reliability and uptime but does not directly address cost-saving. It is more related to performance and resiliency.
- C. Incorrect.
Automated scalability optimizes resource usage but is not the primary factor in cost reduction. It is designed to handle fluctuating workloads effectively.
- D. Incorrect.
Dedicated physical servers are typically more expensive than shared or virtualized resources and are not designed for cost savings.
