With Amazon FSx for OpenZFS, you pay only for the resources you use and there are no minimum fees or setup charges. While pricing is quoted on a monthly basis, your usage is prorated by the second, and you are billed for your average usage over a month. There are four FSx for OpenZFS components to consider when storing and managing your data: SSD storage, SSD IOPS, throughput capacity, and backups.
SSD Storage: You pay for the average amount of storage provisioned for your file systems per month, measured in gigabyte-months "GB-months," as shown in the pricing examples.
SSD IOPS: By default, three IOPS are included for every GB of SSD storage. You can optionally provision a higher level of IOPS, and you pay for the average IOPS provisioned above your included rate for the month, measured in "IOPS-months".
Throughput Capacity: You pay for the average throughput capacity you’ve provisioned for your file systems per month, measured in “MB/s-months.”
Backups: With backups, you pay only for the storage space consumed. Backups are incremental, which means that only the changes after your most recent backup are saved, so you save on storage costs by not duplicating data. You pay for the average amount of backup storage consumed per month, measured in “GB-months.”
Pricing example 1
Assume you want to store 10 TB of general-purpose file data using SSD storage in the US East (N. Virginia) Region. Based on typical compression savings of 50%, you provision a 5 TB Single-AZ file system with 256 MB/s of throughput capacity. Assume you have an average backup storage of 3 TB during the month:
Pricing example 2
Assume you want to store 128 GB of data for short-term testing on SSD storage in the US East (N. Virginia) Region. You provision a 128 GB Single-AZ file system with the minimum throughput capacity of 64 MB/s, and use this file system for 12 hours (43,200 seconds) in a 30-day month. Assume you have not activated compression, and have not used any backup storage.
Data transfer within the same AWS Region
There are no data transfer charges when accessing an Amazon FSx file system within the same Availability Zone (AZ).
If you access your data from the same AWS Region, but from an AZ other than your file system's AZ, you will be charged $0.01/GB in each direction.
