A company has data that is accessed roughly once per month but must be retrievable within milliseconds when needed. The company wants to minimize storage costs while retaining fast retrieval times. Which S3 storage class BEST fits this requirement?
- AS3 Standard
- BS3 Glacier Deep Archive
- CS3 Standard-Infrequent Access (S3 Standard-IA)
- DS3 Glacier Flexible Retrieval
Show answer & explanationAnswer & explanation
Correct answer: C. S3 Standard-Infrequent Access (S3 Standard-IA)
S3 Standard-IA is designed for data accessed infrequently but requiring millisecond retrieval, offering lower storage costs than S3 Standard while charging a retrieval fee.
Why the other options are wrong
- A. S3 Standard is optimized for frequently accessed data and costs more for infrequent use cases.
- B. Glacier Deep Archive is for rarely accessed archival data with retrieval times of hours.
- D. Glacier Flexible Retrieval has retrieval times ranging from minutes to hours, not milliseconds.
S3 Standard-IA
An S3 storage class for infrequently accessed data that requires rapid access when needed, at a lower storage cost than S3 Standard.
- Millisecond access time
- Lower storage cost, but per-GB retrieval fee applies
- Ideal for backups and disaster recovery data
Memory trick: IA: Infrequent visits, Instant Access.
