Amazon Elastic File System (Amazon EFS) provides a simple, serverless, set-and-forget elastic file system for shared data across Amazon Elastic Compute Cloud (EC2) instances or with container and serverless services such as Amazon Elastic Container Service (ECS), Amazon Elastic Kubernetes Service (EKS), AWS Fargate, and AWS Lambda. Until now, customers could choose Amazon EFS Standard storage classes which redundantly store data across multiple geographically separated Availability Zones (AZs) to offer the highest levels of availability and durability.
Today, I am happy to announce Amazon EFS One Zone storage classes, reducing storage costs by 47% compared to Amazon EFS Standard storage classes. As an example, in the US East (N. Virginia) Region, this allows customers to achieve an effective storage price of $0.043/GB-month, assuming you are using lifecycle management and 80% of your data is infrequently accessed. Amazon EFS is designed for eleven 9’s of durability, and EFS One Zone Storage
