AWS Certified Solutions Architect Associate SAA-C03 Practice Question

Amazon S3 Glacier Instant Retrieval is designed for data that is infrequently accessed but requires millisecond retrieval. It offers the lowest storage cost for such data while providing immediate access when needed. Although Amazon S3 Standard-Infrequent Access also provides millisecond retrieval, it has a higher storage cost compared to S3 Glacier Instant Retrieval. Amazon S3 Glacier Deep Archive is more cost-effective in terms of storage cost but does not support millisecond retrieval, as retrieval times can take up to 12 hours. Amazon S3 Standard is intended for frequently accessed data and is more expensive for infrequent access patterns.
