Which action should the company take to meet these requirements MOST cost-effectively?
Configure S3 Standard-Infrequent Access (S3 Standard-IA) storage for the initial storage tier of the objects.
Move the files to S3 Intelligent-Tiering and configure it to move objects to a less expensive storage tier after 90 days.
Configure S3 inventory to manage objects and move them to S3 Standard-Infrequent Access (S3 Standard-1A) after 90 days.
Implement an S3 Lifecycle policy that moves the objects from S3 Standard to S3 Standard-Infrequent Access (S3 Standard-1A) after 90 days.
Explanations:
S3 Standard-IA is a suitable option for infrequently accessed files, but it doesn’t address the need for moving files after a certain period, which is necessary for cost optimization.
S3 Intelligent-Tiering is not the most cost-effective solution here because it incurs additional costs for monitoring and might not provide the expected savings compared to a lifecycle policy.
While configuring S3 inventory can help manage objects, it does not directly automate the transition to S3 Standard-IA after 90 days; thus, it’s not a complete solution by itself.
Implementing an S3 Lifecycle policy that automatically moves files from S3 Standard to S3 Standard-IA after 90 days is the most cost-effective approach, as it ensures files are stored economically based on their access patterns.
I believe the answer is:
Implement an S3 Lifecycle policy that moves the objects from S3 Standard to S3 Standard-Infrequent Access (S3 Standard-1A) after 90 days.
