• Amazon EFS Features

 

feature

Because EFS allows multiple EC2 instances to access the EFS file system simultaneously, EFS can provide a common data source for workloads and applications running on multiple Amazon EC2 instances.

EFS includes a file system interface and file system access semantics (
Strong integrity
and
file locking
etc.) and provides
EFS provides storage that can be accessed by up to thousands of Amazon EC2 instances simultaneously.
The storage is accessible by up to thousands of Amazon EC2 instances at the same time.

 

Amazon EFS is designed to provide the throughput, IOPS, and low latency needed to handle a wide range of workloads and is
General Purpose
and
Maximum I/O
and maximum I/O.

general purpose mode

General Purpose mode not only achieves minimum latency on a per-file-system-operation basis, but also achieves the same results with random or sequential IO patterns. Therefore, selecting the generic mode is necessary to achieve minimum latency.

Maximum I/O Mode

Filesystems in maximum I/O mode can scale throughput to high performance at the cost of slightly longer file operation latency.

 

 

 

Burst function

In EFS, burst throughput mode is selected for cases where accesses suddenly increase
burst throughput mode is selected for cases where accesses suddenly increase.

When burst throughput mode is selected, throughput is scaled to the size of the file system and bursts dynamically as needed to accommodate the irregular nature of many file-based workloads.

This allows EFS to perform well under temporarily high loads.

With burst throughput, throughput is scaled to the size of the file system and bursts dynamically as needed to accommodate the irregular nature of many file-based workloads.

 

Provisioned throughput is designed to support applications that require higher dedicated throughput than the default burst mode and can be set independently of the amount of data stored on the file system.

 

 

 

 

Integration with DataSync

AWS DataSync is a managed data transfer service that allows you to quickly and easily move data between on-premise storage and Amazon EFS. Transfer active data sets via AWS Direct Connect or over the Internet. No application changes or API writing is required. This service can be used for one-time data migration, ongoing workflows with periodic synchronization, and replication for data protection and restoration.

 

About Backup

Use AWS backup.

AWS Backup is a fully managed backup service that makes it easy to centrally manage and automate backups of Amazon EFS file systems.

 

About Storage Class

Amazon EFS is a
standard storage class
and Low Frequency Access Storage Class (EFS IA) and the Low Frequency Access Storage Class (EFS IA).

EFS IA provides optimized cost-effective rates/performance for files that are not accessed daily.

Simply enable EFS lifecycle management on the file system and files not accessed according to the selected lifecycle policy will be automatically and transparently moved to the EFS IA.

EFS IA storage class costs only 0.025 USD/GB-month*!

 

Use EFS IA by enabling lifecycle management and setting up automatic migration to IA classes

EFS Standard storage class is the more expensive class.

Throughput mode is a feature used to determine the overall throughput that can be performed by the file system.

 

Cost Reduction Methods

Amazon EFS uses two storage classes: the standard storage class and the low-frequency access storage class (EFS IA).

EFS IA provides optimized cost-effective rates/performance for files that are not accessed daily.

Enable EFS Lifecycle Management on the file system
Files that are not accessed according to the selected lifecycle policy will be automatically and transparently moved to the EFS IA.

EFS IA storage class costs only 0.025 USD/GB-month*.
