- B . Users can deploy all over the world in minutes.
- C . AWS offers increased speed and agility.
- D . AWS is responsible for patching the infrastructure.
- E . Users benefit from economies of scale.
Correct Answer: A, E
A, E
Explanation:
The statements that represent the cost-effectiveness of the AWS Cloud are:
Users can trade fixed expenses for variable expenses. By using the AWS Cloud, users can pay only for the resources they use, instead of investing in fixed and upfront costs for hardware and software. This can lower the total cost of ownership and increase the return on investment.
Users benefit from economies of scale. By using the AWS Cloud, users can leverage the massive scale and efficiency of AWS to access lower prices and higher performance. AWS passes the cost savings to the users through price reductions and innovations. AWS Cloud Value Framework
