AWS Certified Solutions Architect – Associate (SAA-C03)Design Cost-Optimized ArchitecturesEasy
A financial services company is migrating its on-premises data archiving solution to AWS. They have petabytes of infrequently accessed data that must be retained for seven years due to regulatory compliance. Data retrieval times can be flexible, ranging from several hours to a day. The company wants to minimize storage costs while meeting compliance requirements. Which AWS storage solution is the most cost-effective for this scenario?
- AAmazon S3 Standard
- BAmazon S3 Glacier Deep Archive
- CAmazon EBS Cold HDD (sc1)
- DAmazon S3 Intelligent-Tiering
Show answer & explanationAnswer & explanation
Correct answer: B. Amazon S3 Glacier Deep Archive
Amazon S3 Glacier Deep Archive is designed for long-term archiving of data that is accessed rarely, with retrieval times ranging from 12 hours to 48 hours. It offers the lowest storage cost among S3 storage classes, making it ideal for the described scenario.
Why the other options are wrong
- A. S3 Standard is for frequently accessed data and would be significantly more expensive for archiving.
- C. Amazon EBS Cold HDD (sc1) is a block storage solution for EC2 instances, not an object storage solution for petabyte-scale archiving.
- D. S3 Intelligent-Tiering automatically moves data between access tiers but is not as cost-effective as Glacier Deep Archive for known rarely accessed, long-term archives.
