What type of Amazon S3 storage class is best suited for data that needs to be retained for a minimum of 10 years?

The most suitable Amazon S3 storage class for retaining data for a minimum of 10 years is Glacier. The Glacier storage class is specifically designed for long-term archival of data that is infrequently accessed. It offers low-cost storage for data that does not require immediate retrieval options, making it ideal for compliance and retention requirements where data must be kept for long periods.

Glacier supports a minimum retention period, making it a perfect fit for scenarios where data needs to be stored securely and cost-effectively for years, such as regulatory requirements or historical data preservation. The retrieval time for data stored in Glacier can be longer compared to more accessible storage classes, which aligns with the understanding that this data may not need to be accessed frequently.

While the other options have their own use cases, they do not align with the requirement for long-term storage. Intelligent-Tiering is better suited for data with unpredictable access patterns, Standard is for frequently accessed data, and Standard-IA is intended for infrequently accessed data but does not provide the same long-term cost advantages and retrieval goals as Glacier.
