Amazon Elastic File System (EFS) is designed to provide serverless, fully elastic file storage that helps you share file data without provisioning or managing storage capacity and performance. There is no minimum fee or setup charge. You pay only for the primary and backup storage you use and for your read, write, and tiering activity to your EFS file system. You pay for read and write access using Elastic Throughput (but you can optionally provision throughput performance up front using Provisioned Throughput), and for tiering data to EFS’s Infrequent Access and Archive storage classes.

EFS offers price advantages see the EFS over many self-managed cloud alternatives, delivering a total cost of ownership (TCO) as low as $0.0315/GB, with performance that automatically scales to tens of GB/s and hundreds of thousands of IOPS. For more information on how much you can save, see the EFS Pricing examples and the Total Cost of Ownership (TCO) example here.

Amazon EFS offers three storage classes: EFS Standard, which delivers sub-millisecond latency performance for actively-used data; EFS Infrequent Access (EFS IA), which is cost-optimized for data accessed only a few times a quarter; and EFS Archive, which is cost-optimized for long-lived data accessed a few times a year or less. 

Amazon EFS also offers data protection for your files with EFS Backup and EFS Replication. With EFS Backup, you pay only for the amount of backup storage you use and the amount of backup data you restore in the month. There is no minimum fee and there are no setup charges. Visit AWS Backup to learn more. Use EFS Replication to replicate your file system to a Region or Availability Zone (AZ) of your choice without having to manage additional infrastructure or custom processes.  

Pricing table

Within your first 12 months on AWS, you can use up to 5 GB/month on the EFS Standard storage class at no charge.

  • Regional (Multi-AZ) with Elastic Throughput
  • Regional (Multi-AZ) with legacy throughput modes
  • One Zone (Single-AZ)
  • Replication and Data transfer
  • You are charged the prevailing EC2 data transfer rates for cross-AZ or cross-Region activity when you access your EFS file system, including when using EFS Replication to replicate file system data across AZs or Regions.


    Replication and data transfer within the same AWS Region
    There are no data transfer charges when accessing an EFS mount target from within the same Availability Zone (AZ), or when replicating data across EFS file systems within the same AZ.


    If you access your EFS mount target from another AZ, you will be charged the EC2 cross-AZ data transfer rate ($0.01/GB) for data transfer “in” and “out” of the AZ. If you replicate EFS One Zone file system data across AZs for, you pay the EC2 cross-AZ data transfer rate for data transfer “out” from the source AZ.


    For more information, refer to Data Transfer within the same AWS Region on the Amazon EC2 On-Demand Pricing page.


    Replication and data transfer across AWS Regions
    Replication and data transfer activity across AWS Regions are subject to EC2 cross-Region data transfer rates. If you replicate data across Regions, you pay the EC2 inter-Region data transfer rate for data transfer “out” of the source Region
    .
    For more information, refer to Data Transfer on the Amazon EC2 On-Demand Pricing page.

AWS Free Tier

As part of the AWS Free Tier, you can get started with EFS for free. Upon sign-up, new AWS customers receive 5 GB of EFS Standard storage with a Regional file system for 12 months. The AWS Free Tier is not applicable to files stored in the One Zone storage file system type.  

Your usage for the Free Tier is calculated each month across all AWS Regions except the AWS GovCloud Region and automatically applied to your bill; unused monthly usage will not roll over. Restrictions apply; see offer terms for more details.
