Analysis:
The company's requirements are to migrate 5 PB of data from physical tapes to AWS within 6 months, preserve the data for 10 years, and ensure cost efficiency.AWS Storage Gateway Tape Gatewayis purpose-built for such use cases, as it seamlessly integrates with backup applications and provides virtual tape storage in Amazon S3 Glacier Deep Archive.
Why Option D is Correct:
Tape Gateway: Enables the migration of physical tapes to virtual tapes. Virtual tapes are stored in Amazon S3 and can later be archived in Amazon S3 Glacier Deep Archive for long-term storage.
Cost Efficiency: Amazon S3 Glacier Deep Archive is the lowest-cost storage class for long-term data preservation.
Operational Simplicity: Tape Gateway integrates with existing on-premises backup software, reducing the need for additional tools or manual processes.
Scalability: Can handle the migration of large datasets, such as 5 PB, within the required timeframe.
Why Other Options Are Not Ideal:
Option A:
AWS DataSync is not designed for reading data directly from physical tapes. Staging the data on local storage adds unnecessary complexity and cost.Not suitable.
Option B:
Using backup applications to write directly to S3 Glacier Deep Archive may not leverage AWS-native services optimally. Tape Gateway simplifies the workflow significantly.Less efficient.
Option C:
Snowball Edge is ideal for environments without high-bandwidth connectivity. However, the company already has a 10 Gbps Direct Connect, making Tape Gateway a better choice.Not cost-effective.
