Amazon S3 Glacier Instant Retrieval is an archive storage class that delivers the lowest-cost storage for long-lived data that is rarely accessed and requires retrieval in milliseconds. With S3 Glacier Instant Retrieval, you can save up to 68% on storage costs compared to using the S3 Standard-Infrequent Access (S3 Standard-IA) storage class, when your data is accessed once per quarter.https://aws.amazon.com/s3/storage-classes/glacier/instant-retrieval/

Understanding Storage Requirements:

Files are large and infrequently accessed, but need to be available within minutes when requested in the first year.

Long-term (7-year) retention is required.

Cost-effectiveness is a top priority.

Why S3 Glacier Instant Retrieval:

Matches the retrieval requirements (access within minutes).

More cost-effective than S3 Standard for infrequently accessed data.

Simpler to use than traditional Glacier where retrievals take hours.

Why S3 Glacier Deep Archive:

Most cost-effective S3 storage class for long term archival.

Meets the 7-year retention requirement.

S3 Lifecycle Policy:

Automate the transition from Glacier Instant Retrieval to Glacier Deep Archive after one year.

Optimize costs by matching storage classes to access patterns.
