A business must move its web application to AWS. The majority of the computing power is continuously used all year.

Which of the following would be the most cost-effective solution?

Correct! Wrong!

Explanation:
Reserved Instances (RIs) would be a good option for a company that needs to migrate its web application to AWS and has consistent, predictable usage throughout the year. With Reserved Instances, the company can commit to a one- or three-year term of usage for a certain amount of computing capacity, which can provide significant cost savings compared to On-Demand Instances. Reserved Instances offer a lower hourly rate than On-Demand Instances, and the savings can be even greater with the upfront payment options. Additionally, Reserved Instances can provide capacity reservations, which can help ensure that the company has the computing capacity they need when they need it. However, Reserved Instances require an upfront commitment, and the company may need to plan to make sure they are using the right instance type and have the right amount of capacity reserved.

AWS Identity and Access Management (IAM) is the service that would help the company perform the same role in AWS as their operations team that takes care of ID management in their on-premises data center.

With IAM, the company can create and manage AWS users and groups, and control access to AWS resources using permissions.

IAM also provides integration with AWS CloudTrail, which allows the company to audit and monitor user activity and changes made to their AWS environment.
