Amazon Elastic File System (Amazon EFS) provides 4 storage courses: two Customary storage courses, Amazon EFS Customary and Amazon EFS Customary-Rare Entry (EFS Customary-IA), and two One Zone storage courses, Amazon EFS One Zone, and Amazon EFS One Zone-Rare Entry (EFS One Zone-IA). Customary storage courses retailer knowledge inside and throughout a number of availability zones (AZ). One Zone storage courses retailer knowledge redundantly inside a single AZ, at 47 p.c cheaper price in comparison with file programs utilizing Customary storage courses, for workloads that don’t require multi-AZ resilience.
The EFS Customary and EFS One Zone storage courses are performance-optimized to ship decrease latency. The Rare Entry (IA) storage courses are cost-optimized for information that aren’t accessed day by day. With EFS lifecycle administration, you may transfer information that haven’t been accessed during the lifecycle coverage (7, 14, 30, 60, or 90 days) to the IA storage courses. This may cut back the price of your storage by as much as 92 p.c in comparison with EFS Customary and EFS One Zone storage courses respectively.
Clients love the associated fee financial savings supplied by the IA storage courses, however in addition they wish to make sure that they gained’t get surprising knowledge entry fees if entry patterns change and information which have transitioned to IA are accessed often. Studying from or writing knowledge to the IA storage courses incurs an information entry cost for each entry.
Right this moment, we’re launching Amazon EFS Clever-Tiering, a brand new EFS lifecycle administration function that routinely optimizes prices for shared file storage when knowledge entry patterns change, with out operational overhead.
With EFS Clever-Tiering, lifecycle administration displays the entry patterns of your file system and strikes information that haven’t been accessed during the lifecycle coverage from EFS Customary or EFS One Zone to EFS Customary-IA or EFS One Zone-IA, relying on whether or not your file system makes use of EFS Customary or EFS One Zone storage courses. If the file is accessed once more, it’s moved again to EFS Customary or EFS One Zone storage courses.
EFS Clever-Tiering optimizes your prices even when your workload file knowledge entry patterns change. You’ll by no means have to fret about unbounded knowledge entry fees since you solely pay for knowledge entry fees for transitions between storage courses.
Getting began with EFS Clever-Tiering
To get began with EFS Clever-Tiering, create a file system utilizing the AWS Administration Console, allow lifecyle administration and set two lifecycle insurance policies.
Select a Transition into IA possibility to maneuver occasionally accessed information to the IA storage courses. From the drop down record, you may select lifecycle insurance policies of seven, 14, 30, 60, or 90 days. Moreover, select a Transition out of IA possibility and choose On first entry to maneuver information again to EFS Customary or EFS One Zone storage courses on entry.
For an current file system, you may click on the Edit button in your file system to allow or change lifecycle administration and EFS Clever-Tiering.
Additionally, you need to use the
PutLifecycleConfiguration API motion or put-lifecycle-configuration command specifying the file system ID of the file system for which you’re enabling lifecycle administration and the 2 insurance policies for EFS Clever-Tiering.
$ aws efs put-lifecycle-configuration --file-system-id File-System-ID --lifecycle-policies "[, ]" --region us-west-2 --profile adminuser
You get the next response:
"LifecyclePolicies": [ , "TransitionToPrimaryStorageClass": "AFTER_1_ACCESS" ]
To disable EFS Clever-Tiering, set each the Transition into IA and Transition out of IA choices to None. This may disable lifecycle administration, and your information will stay on the storage class they’re on.
Any information which have already began to maneuver between storage courses on the time that you simply disabled EFS Clever-Tiering will full transferring to their new storage class. You’ll be able to disable transition insurance policies independently of one another.

Amazon EFS Clever-Tiering is obtainable in all AWS Areas the place Amazon EFS is obtainable. To study extra, be a part of us for the third annual and utterly free-to-attend AWS Storage Day 2021 and tune in to our livestream on the AWS Twitch channel in the present day.
You’ll be able to ship suggestions to the AWS discussion board for Amazon EFS or by means of your traditional AWS Assist contacts.
