Which solution meets these requirements?
Store the files in Amazon S3 Standard. Create an S3 Lifecycle policy that moves objects that are more than 90 days old to S3 Glacier.
Store the files in Amazon S3 Standard. Create an S3 Lifecycle policy that moves objects that are more than 90 days old to S3 Standard-Infrequent Access (S3 Standard-IA).
Store the files in Amazon Elastic Block Store (Amazon EBS) volumes. Schedule snapshots of the volumes. Use the snapshots to archive data that is more than 90 days old.
Store the files in RAID-striped Amazon Elastic Block Store (Amazon EBS) volumes. Schedule snapshots of the volumes. Use the snapshots to archive data that is more than 90 days old.
Explanations:
S3 Glacier is designed for archival storage and does not support instant access. Moving files to S3 Glacier would not meet the requirement of ensuring instant availability.
S3 Standard-IA is ideal for data that is accessed less frequently but still needs to be available instantly. This option supports cost-effective storage with instant access.
Amazon EBS is generally used for block storage attached to EC2 instances and does not scale as efficiently as Amazon S3 for petabyte-level storage needs with high durability.
Using RAID-striped EBS volumes can provide better performance but is not optimal for scalable, petabyte-level storage and lacks the durability and cost-effectiveness of S3 tiers.
I categorize that the answer is:
Store the files in Amazon S3 Standard. Create an S3 Lifecycle policy that moves objects that are more than 90 days old to S3 Standard-Infrequent Access (S3 Standard-IA).
