Explanation:
A physical server with an EC2 instance capacity that is exclusively yours is an Amazon EC2 Dedicated Host. You can use your current per-socket, per-core, or per-VM software licenses on dedicated hosts, such as those for Windows Server, Microsoft SQL Server, SUSE, and Linux Enterprise Server.
You can run many types of database software on Amazon RDS, a managed relational database server. Service management means less database administration is required than would otherwise be the case. Hardware provisioning, database configuration, patching, and backups are all included in the managed service.
Explanation:
Companies can transition from fixed costs to variable costs with pay-as-you-go pricing by only paying for what they use. AWS does not have any fixed-term contracts. Thus that criterion is also satisfied.

A business's infrastructure is housed in a data center on its property. Currently, ID management is handled by an operations team.
Which of the following services would assist them in performing the same function in AWS if they decided to shift to the cloud?
Explanation:
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. IAM is a web service that provides secure access to AWS resources. IAM allows the company to manage access to AWS services and resources securely. With IAM, the company can create and manage AWS users and groups, and control access to AWS resources using permissions. IAM provides fine-grained access control to AWS resources, which enables the company to give users only the necessary permissions to perform their tasks. IAM also provides integration with AWS CloudTrail, which allows the company to audit and monitor user activity and changes made to their AWS environment.
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?
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.
