  3. Amazon S3 Glacier Deep ArchiveCevap

Cevap

Amazon S3 Glacier Deep Archive is the most cost-effective choice because it is specifically designed for long-term archival storage with retrieval times of up to 12 hours.
Amazon S3 Glacier Deep Archive is the correct choice because it is AWS's lowest-cost storage class, specifically optimized for archiving data that is rarely accessed and can tolerate retrieval times of up to 12 hours.

Adım Adım Çözüm

1
Analyze the workload requirements: long-term retention (7 years), rare access, high tolerance for retrieval latency (12 hours), and a primary focus on cost optimization.
The requirements point toward an archival storage solution rather than active performance-focused storage.
Identifying the data access patterns and latency tolerance helps narrow down the service class.
2
Compare the features and pricing of the available storage classes and services.
Amazon S3 Glacier Deep Archive provides the lowest storage cost on AWS with standard retrieval times within 12 hours.
This step determines the exact service that matches the cost-efficiency and retrieval-time requirements.
