Which storage solution is MOST cost-effective?
Store the data in Amazon S3 Standard. Set a lifecycle rule to transition the data to S3 Glacier Deep Archive after 1 year. Set a lifecycle rule to delete the data after 5 years.
Store the data in Amazon S3 One Zone-Infrequent Access (S3 One Zone-IA). Set a lifecycle rule to transition the data to S3 Glacier after 1 year. Set the lifecycle rule to delete the data after 5 years.
Store the data in Amazon S3 Standard. Set a lifecycle rule to transition the data to S3 Standard-Infrequent Access (S3 Standard-IA) after 1 year. Set a lifecycle rule to delete the data after 5 years.
Store the data in Amazon S3 Standard. Set a lifecycle rule to transition the data to S3 One Zone-Infrequent Access (S3 One Zone-IA) after 1 year. Set a lifecycle rule to delete the data after 5 years.
Explanations:
Storing data in Amazon S3 Standard allows for easy access during the first year. Transitioning to S3 Glacier Deep Archive after 1 year significantly reduces storage costs for data that is infrequently accessed, and the 5-year retention policy aligns with compliance requirements.
Using S3 One Zone-IA for the initial storage may lead to data loss in the event of an Availability Zone failure. Although transitioning to S3 Glacier after 1 year is cost-effective, the risk of data loss makes this option less desirable.
Transitioning to S3 Standard-IA after 1 year does not provide as much cost savings compared to Glacier options. While it meets the retention requirement, it may not be the most economical choice for long-term storage.
Transitioning to S3 One Zone-IA after 1 year carries the same risk of data loss as option B. Although it is cost-effective for infrequent access, the risk and potential compliance issues make it less favorable compared to using Glacier.
I plan that the answer is:
Store the data in Amazon S3 Standard. Set a lifecycle rule to transition the data to S3 Glacier Deep Archive after 1 year. Set a lifecycle rule to delete the data after 5 years.
