Amazon  Elastic File System(EFS) presents a straightforward, versatile, flexible record machine for Linux-based remaining burdens for use with AWS Cloud contributions. It is built to scale on demand to petabytes without disrupting applications, developing and shrinking mechanically as you add and cast-off files, so your applications have the storage they want – when they need it. Amazon EFS is a completely managed provider that requires no modifications to your existing applications and tools, imparting get entry through a public file gadget interface for seamless integration. There is a Standard and an Infrequent Access storage class available with Amazon EFS. Using Lifecycle Management, records not got to for 30 days will consequently be moved to an expense improved Infrequent Access stockpiling class, giving you a basic method to store and get right of section to dynamic and occasionally accessed file system statistics in the equal file device whilst decreasing storage charges by using up to 85%. Amazon EFS is a regional service storing facts within and across multiple Availability Zones (AZs) for excessive availability and durability. You can access your file systems throughout AZs, regions, and VPCs and share archives between lots of Amazon EC2 cases and on-premises servers via AWS Direct Connect or AWS VPN.

Amazon EFS is nicely desirable to aid a broad spectrum of use cases from relatively parallelized, scale-out workloads that require the most noteworthy feasible throughput to single-strung, inertness touchy remaining burdens. Use cases such as lift-and-shift corporation applications, massive data analytics, web serving, and content management, software development and testing, media and enjoyment workflows, database backups, and container storage.


Benefits of Amazon EFS

Dynamic Elasticity

Amazon EFS mechanically and immediately scales your file device storage ability up or down as you add or remove documents, you need – when you require it. You create your file machine and begin including archives with no want to provision storage in advance.

Scalable Performance

Amazon EFS is designed to furnish the throughput, IOPS, and low latency wanted for Linux workloads. Throughput and IOPS scale as a file gadget grow and can burst to more significant throughput stages for brief intervals to help the unpredictable overall performance wishes of file workloads. For the most stressful workloads, Amazon EFS can aid overall performance over 10 GB/sec and up to 500,000 IOPS.

Shared file storage

Amazon EFS provides impervious get admission to for hundreds of connections. Amazon EC2 situations and on-premises servers can simultaneously get entry to a shared Amazon EFS file machine the use of a traditional file permissions model, file locking capabilities, and hierarchical listing shape using the NFSv4 protocol. Amazon EC2 cases can access your file machine throughout AZs and regions whilst on-premises servers can get admission to the usage of AWS Direct Connect or AWS VPN.

Fully Managed

Amazon EFS is a wholly managed service offering shared file device storage for Linux workloads. It presents a simple interface allowing you to create and configure file structures rapidly and manages the file storage infrastructure for you, disposing of the complexity of deploying, patching and retaining the underpinnings of a file system.


With Amazon EFS storage, you pay only for what you use. There is no want to provision storage to develop, and there are no minimum commitments or up-front fees. With Lifecycle Management, you can routinely move archives that have no longer been accessed for 30 days to a cost-optimized storage class, lowering storage costs with the aid of up to 85%.

Security and compliance

Amazon EFS approves you to securely access your files the usage of your present protection infrastructure. Control get admission to your Amazon EFS file systems with POSIX permissions, Amazon VPC, and AWS IAM.


How it works


Use cases

Lift-and-shift agency applications

Amazon EFS gives the scalability, elasticity, availability, and sturdiness to be the file store for enterprise purposes and applications delivered as a service. Its well-known file device interface, file gadget permissions, and directory hierarchy make it easy to migrate agency functions from on-premises to the AWS cloud or to construct new ones.

Big records analytics

Amazon EFS bears the scale and in general execution for tremendous insights purposes that require high throughput to figure hubs combined with read-after-compose consistency and low-inertness document activities. Many analytics workloads engage with facts by using a file interface, requiring file permissions, a listing hierarchy, file locks, and the ability to write to portions of a file.

Web serving & content management

Amazon EFS presents a durable, excessive throughput file device for content management systems and internet serving functions that save and serve information for a range of applications like websites, online publications, and archives. Since Amazon EFS adheres to the expected file device listing structure, file naming conventions, and permissions that internet developers are accustomed to, it can easily combine with internet applications.

An application trying out & development

Amazon EFS provides your development environments a frequent storage repository that offers you the potential to share code and other files in a safe and equipped way. Amazon EFS offers a scalable and fantastically available solution that is ideal for trying out and development workloads.

Media & entertainment

Media workflows like video editing, studio production, broadcast processing, sound design, and rendering regularly depend on shared storage to manipulate large files. Amazon EFS gives a robust facts consistency mannequin with excessive throughput and shared file access which can minimize the time it takes to perform these jobs and consolidate a couple of nearby file repositories into a single area for all users.

Database backups

Amazon EFS presents a fashionable file system that can be effortlessly installed with NFSv4 from database servers. This gives an ideal platform to create transportable database backups using native software equipment or company backup applications. Many organizations desire to take benefit of the flexibility of storing database backups in the cloud both for temporary safety during updates or for improvement and test.

Container storage

Amazon EFS is perfect for container storage imparting continual shared access to a frequent file repository. Containers are an essential section of building microservices due to the fact they’re speedy to provision, effortlessly portable, and supply method isolation. Containers that need get right of entry to the authentic records every time they start can take benefit of a shared file device that they can join to regardless of which occasion they’re going for walks on.
