Which solution will meet these requirements with the LEAST cost?
Use a Provisioned IOPS SSD (io1) Amazon Elastic Block Store (Amazon EBS) volume that is configured with 10,000 provisioned IOPS.
Use a General Purpose SSD (gp3) Amazon Elastic Block Store (Amazon EBS) volume that is configured with 10,000 provisioned IOPS.
Use an Amazon Elastic File System (Amazon EFS) file system in Max I/O mode.
Use an Amazon FSx for Windows File Server file system that is configured with 10,000 IOPS.
Explanations:
Provisioned IOPS SSD (io1) volumes require a higher minimum storage size to provision 10,000 IOPS, leading to unnecessary costs since it is based on both IOPS and the storage capacity provisioned.
General Purpose SSD (gp3) volumes can be provisioned for up to 16,000 IOPS independently of the volume size. This allows achieving 10,000 IOPS at a lower cost compared to io1 while only paying for the actual storage capacity used.
Amazon EFS in Max I/O mode provides high throughput and IOPS but is typically more expensive than EBS options for consistent IOPS performance and may not guarantee the needed 10,000 IOPS consistently at a lower cost.
Amazon FSx for Windows File Server can provide high IOPS but involves additional overhead and costs associated with managing a fully managed file system, making it less cost-effective for just achieving 10,000 IOPS compared to the gp3 option.
It appears that the answer is:
Use a General Purpose SSD (gp3) Amazon Elastic Block Store (Amazon EBS) volume that is configured with 10,000 provisioned IOPS.
