A company is migrating workloads to AWS. It has sensitive and critical data in on-premises relational databases running SQL Server. The company wants to increase security and reduce operational overhead in the cloud. Which solution meets these requirements?

Migrating to a Multi-AZ Amazon RDS for SQL Server DB instance directly addresses the requirements. RDS is a managed service, significantly reducing operational overhead compared to managing databases on EC2 instances. The Multi-AZ deployment option provides high availability and automatic failover, crucial for critical data. Using an AWS KMS AWS managed key for encryption ensures data security at rest, meeting the sensitive data requirement. Migrating to EC2 instances increases operational overhead as the company would still be responsible for database patching, backups, and high availability. Migrating data to an S3 bucket or DynamoDB table would require significant application re-architecture, as these are not relational databases, and would not be a direct migration path for SQL Server. While Macie and CloudWatch Logs are security services, they don't replace the core database migration and management solution.
