Amazon Elastic File System (Amazon EFS) for cross-Amazon Elastic Compute Cloud (EC2) instances, and Amazon Elastic Container Service (ECS) , Amazon Elastic Kubernetes Service (EKS) , Amazon Fargate and Amazon the Lambda such as 161e52209608a1 provide a simple, fully managed, elastic data sharing file system. Currently, customers can use Amazon EFS Standard storage class, by a plurality of independent available geographic area obtain redundant data storage service having the highest availability and durability .

Recently, we are pleased to announce that the Amazon EFS One Zone storage class reduces storage costs by up to 47% compared to the previous Amazon EFS Standard storage class. Taking the US East (Northern Virginia) Region as an example, assuming that 80% of the data you use has a certain life cycle and is accessed infrequently, the customer's actual monthly storage cost per GB is $0.043. Amazon EFS is designed to support 11 nines (99.999999999%) of data durability, and Amazon EFS One Zone supports 3 nines (99.9%) availability SLA while maintaining the same elasticity, simplicity, and scalability as the Amazon EFS Standard storage class Features such as performance and life cycle management.

We're introducing two new Availability Zone storage classes - Amazon EFS One Zone, which costs $0.16 per GB per month of storage in the US East (N. Virginia) Region; and Amazon EFS One Zone-Infrequent Access (One Zone-IA), the monthly storage cost per GB in the US East (Northern Virginia) region is $0.0133. All file systems using the One Zone storage class can use Amazon Backup to configure automatic backup policies, thereby providing a higher level of data protection; in addition, file systems created by the Amazon EFS console also have lifecycle management policies by default, The ability to automatically and transparently move less frequently accessed files to the Amazon EFS One Zone-IA storage class. By working with lifecycle management, users can reduce storage costs for infrequently accessed data by up to 92%.
The One Zone storage class is ideal for supporting a wide variety of workloads (e.g. development, build, and staging environments) and applications (e.g. analytics, simulation, etc.) and media transcoding). In addition, this new storage class can also be ideal for storing data backups, secondary copies of data in a customer's local computer room, a variety of data for easy reconstruction, and data storage scenarios where applications have built-in replication and high-availability features.
Quick Start One Zone Storage Class
To get started with the Amazon EFS One Zone storage class, we can create a new file system using the Amazon EFS console, the Amazon Command Line Interface (CLI), or the Amazon SDK.
In the Amazon EFS console, click Create file system, specify One Zone for the Availability and Durability option you selected, and then select an Availability Zone to create a file system with recommended settings, including automatic backups and default lifecycle management. The entire creation process only takes a few seconds.
Compared with the Amazon EFS Standard storage class, Amazon EFS One Zone storage class provide the same functionality, API console experience, you can Amazon Direct Connect or Amazon VPN as an example, container, no local or server applications Servers create and access shared file storage systems.

You can use Amazon ECS with the Amazon EFS file system to share file system data across a cluster of container instances, ensuring that tasks on any instance can access the same persistent data. To use the Amazon EFS One Zone storage class with Amazon ECS, you need to specify its subnet in the same Availability Zone as the file system when you launch the job.
On the Amazon EKS side, you can use the Amazon EFS Container Storage Interface (CSI) driver to share the same filesystem between multiple pods within the same Amazon EKS or managed Kubernetes cluster via an Amazon EFS access point . The Amazon EFS CSI driver is integrated into the Fargate stack and can directly support the use of Amazon EFS. Using the Amazno EFS CSI driver with the Amazon EFS One Zone storage class allows you to use the nodeSelector option when launching a pod, which ensures that the pod is scheduled in the same Availability Zone as the filesystem.

Amazon EFS can also cooperate with Amazon Lambda to implement shared data invocation across functions, read large-scale data files, and save the processing results of functions on persistent shared file storage. Amazon Lambda securely connects each function instance to an Amazon EFS mount point within the same Availability Zone and subnet. When using the Amazon EFS One Zone storage class with Amazon Lambda, be careful to configure your function to only accept calls from subnets that are in the same Availability Zone as the file system.
Here are some important features of Amazon EFS One Zone:
Durability and Availability: Because the Amazon EFS One Zone storage class stores data in the same Availability Zone, a disaster or other failure that affects all copies of data in that Availability Zone could result in data loss. For customers with higher requirements for durability and availability, we recommend that you use the Amazon EFS Standard storage class option that spans multiple Availability Zones.
Backup: As mentioned earlier, if you did not adjust the default backup settings when you created the file system, the file system corresponding to the Amazon EFS One Zone storage class will automatically use the Amazon Backup backup mechanism. The backup data will be replicated to the 3 Availability Zones in the same region, and you can further replicate it to other Availability Zones or Regions through a restore operation.
is now online
Amazon EFS One Zone storage class is now available in US East (N. Virginia), US East (Ohio), US West (Northern California), US West (Oregon), South America (Sao Paulo), EU (Ireland), Europe (Frankfurt), Europe (Milan), Europe (Stockholm), Asia Pacific (Singapore), Asia Pacific (Sydney), Asia Pacific (Tokyo), Asia Pacific (Seoul), Asia Pacific (Mumbai), Asia Pacific (Hong Kong) , Africa (Cape Town), Middle East (Bahrain), all Amazon GovCloud (US) regions, as well as Amazon Cloud China (Ningxia) regions (operated by NWCD) and Amazon Cloud China (Beijing) regions (operated by Halo New network operation). In the future, this program will also land in more regions. For more details, see documentation .
