Which solution will meet these requirements?
Perform a database backup. Copy the backup files to an AWS Snowball Edge Storage Optimized device. Import the backup to Amazon S3. Use server-side encryption with Amazon S3 managed encryption keys (SSE-S3) for encryption at rest. Use TLS for encryption in transit. Import the data from Amazon S3 to the DB instance.
Use AWS Database Migration Service (AWS DMS) to migrate the data to AWS. Create a DMS replication instance in a private subnet. Create VPC endpoints for AWS DMS. Configure a DMS task to copy data from the on-premises database to the DB instance by using full load plus change data capture (CDC). Use the AWS Key Management Service (AWS KMS) default key for encryption at rest. Use TLS for encryption in transit.
Perform a database backup. Use AWS DataSync to transfer the backup files to Amazon S3. Use server-side encryption with Amazon S3 managed encryption keys (SSE-S3) for encryption at rest. Use TLS for encryption in transit. Import the data from Amazon S3 to the DB instance.
Use Amazon S3 File Gateway. Set up a private connection to Amazon S3 by using AWS PrivateLink. Perform a database backup. Copy the backup files to Amazon S3. Use server-side encryption with Amazon S3 managed encryption keys (SSE-S3) for encryption at rest. Use TLS for encryption in transit. Import the data from Amazon S3 to the DB instance.
Explanations:
AWS Snowball Edge is a physical device that is typically used for large-scale data transfer. While it meets the requirement of not transferring data over the internet, it adds unnecessary complexity and downtime compared to a continuous migration solution. Additionally, Snowball Edge does not directly support replication or change data capture (CDC) for ongoing data updates, which is crucial in this scenario.
AWS DMS is designed for database migration with minimal downtime, supporting full load plus change data capture (CDC). It uses private VPC endpoints, ensuring that data is transferred securely within the AWS network (not over the internet). It also supports encryption in transit (TLS) and at rest (via AWS KMS). This solution aligns well with the need for minimal downtime and secure migration.
AWS DataSync is more suited for transferring large files or objects (e.g., for large backups), not for migrating databases with constant updates. While DataSync supports encryption in transit and at rest, it lacks the ability to handle CDC for continuous updates, making it unsuitable for the real-time data transfer requirement.
Amazon S3 File Gateway is designed for file-based storage solutions, not for direct database migration. It would involve unnecessary complexity and downtime. Additionally, like AWS DataSync, it does not support CDC for continuous data updates. The solution also relies on S3 storage, but does not directly address the real-time nature of database updates.
My best guess is:
Use AWS Database Migration Service (AWS DMS) to migrate the data to AWS. Create a DMS replication instance in a private subnet. Create VPC endpoints for AWS DMS. Configure a DMS task to copy data from the on-premises database to the DB instance by using full load plus change data capture (CDC). Use the AWS Key Management Service (AWS KMS) default key for encryption at rest. Use TLS for encryption in transit.
