Amazon FSx for Lustre: Lustre is a high-performance file system designed for workloads that require fast storage with sustained high throughput and low latency. It integrates with Amazon S3, making it suitable for HPC environments.

Persistent File Systems:

Persistent Storage: Suitable for long-term storage and recurrent use, providing durability and availability.

High Throughput and Low Latency: Persistent Lustre file systems can handle large amounts of data with sub-millisecond latency, meeting the needs of high-performance computing workloads.

Simultaneous Access: FSx for Lustre allows thousands of compute instances to access and process large datasets concurrently, ensuring that the high volume of data is handled efficiently.

Highly Available: FSx for Lustre is designed to provide high availability and is managed by AWS, reducing the operational burden.

S3 Glacier Flexible Retrieval is designed for long-lived archive data that is accessed infrequently and can be retrieved in minutes to hours, making it a strong cost-effective choice for medical records that are rarely accessed. AWS documentation states that standard retrievals from this storage class typically finish in 3 to 5 hours, which fits the requirement to retrieve records within a few hours. For immutability, AWS S3 Object Lock provides a WORM model and can prevent deletion or overwriting for a fixed retention period. Together, Glacier Flexible Retrieval and Object Lock satisfy the needs for low-cost archival storage, long retention, immutability, and acceptable restore times. S3 Standard and Intelligent-Tiering cost more than necessary for rarely accessed 10-year data, and One Zone-IA does not provide the same resilience posture.

============

S3 Intelligent-Tiering is designed for data with unknown or changing access patterns. It automatically moves objects between frequent and infrequent access tiers as needed, with no retrieval fees for accessing data in any tier, and no performance impact. Minimal management overhead is required because AWS manages all transitions automatically. This class is cost-optimized and meets all requirements listed.

AWS Documentation Extract:

" S3 Intelligent-Tiering is the only storage class that automatically moves data between frequent and infrequent access tiers when access patterns change, with no retrieval charges and no impact on performance. It is designed to optimize costs automatically when data access patterns are unpredictable. "

Other options:

B: Storage class analysis only provides recommendations, not actual storage tiering.

C & D: S3 Standard-IA and S3 One Zone-IA both have retrieval fees and may impact retrieval time and data durability.
