Amazon Elastic File System (EFS) review
Elastic NFS file storage for Linux workloads running across AWS services.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Amazon Elastic File System (EFS) is a managed, shared cloud file system for Linux workloads. It provides NFSv4.0 and NFSv4.1 access for AWS compute services, including Amazon EC2, Amazon ECS, Amazon EKS, AWS Fargate, and AWS Lambda. EFS can grow and shrink automatically, making it suited to teams that need shared file storage without managing fixed capacity. Regional and One Zone file systems support different deployment requirements, while on-premises Linux servers can also access EFS.
EFS uses usage-based pricing rather than fixed capacity plans. The published EFS Standard storage price is $0.30 per GB per month, with charges based on storage used. Pricing varies by Region, storage class, throughput, access, replication, and backup usage. Lifecycle management can move data across Standard, Infrequent Access, and Archive storage classes, while Elastic and Provisioned throughput modes provide different ways to handle performance requirements. Buyers should therefore assess expected storage, access patterns, and related AWS services before estimating monthly costs. There is no permanent free plan.
Its strongest fit is within the AWS ecosystem. Integrations include AWS Backup, AWS DataSync, AWS Transfer Family, Amazon CloudWatch, AWS CloudFormation, AWS CloudTrail, and AWS Identity and Access Management, alongside AWS compute services. Cross-Region file-system replication and encryption at rest and in transit add data-protection capabilities. Choose EFS when elastic, shared NFS storage is central to an AWS-based Linux architecture. Organizations seeking a general-purpose file platform outside AWS, or a storage service not centered on Linux and NFS, should consider alternatives.
