It is mandatory to have Oracle Enterprise Linux(OEL) as the operating system for running Oracle database for SAP.

This is the most operationally efficient solution that meets the company's security policy requirements. AWS KMS is a service that enables you to create and manage encryption keys that are used to encrypt and decrypt data. By configuring AWS Backup Agent for SAP HANA to use AWS KMS for SAP backups, the company can ensure that the backups are encrypted at rest and that only authorized team members have the ability to decrypt them. The key policy allows the company to define which team members are authorized to access the key, so that it can be used to decrypt the backup. This approach is operationally efficient because it does not require the company to manually encrypt and decrypt backups, and it enables the company to manage access to the encryption key through IAM policies, without the need for sharing encryption keys.

The AWS Data Provider for SAP requires the ability to access metrics data in order to return metrics to the SAP application. The IAM policy statement with Sid "AWSDataProvider1" currently does not have the necessary permissions to access metrics data. The SAP solutions architect should add the cloudwatch:GetMetricStatistics action to the policy statement with Sid "AWSDataProvider1" to grant the necessary permissions for the Data Provider to access metrics data.

The other actions such as "EC2:DescribeInstances" and "EC2:DescribeVolumes" are not related to CloudWatch metrics and only provide the ability to describe EC2 instances and volumes. Actions such as "s3:GetObject" are not related to CloudWatch metrics, it's used to get an object from an S3 bucket. Actions such as "cloudwatch:ListMetrics" and "cloudwatch:DescribeAlarmsForMetric" would not be necessary for the AWS Data Provider for SAP to return metrics to the SAP application and it's not related to the problem described.
