Amazon Elastic File System (Amazon EFS) provides simple, scalable file storage for use with Amazon EC2 instances in the AWS Cloud.
Amazon Elastic File System (Amazon EFS) provides simple, scalable file storage for use with Amazon EC2 instances in the AWS Cloud. Amazon EFS is easy to use and offers a simple interface that allows you to create and configure file systems quickly and easily. With Amazon EFS, storage capacity is elastic, growing and shrinking automatically as you add and remove files, so your applications have the storage they need, when they need it.
When mounted on Amazon EC2 instances, an Amazon EFS file system provides a standard file system interface and file system access semantics, allowing you to seamlessly integrate Amazon EFS with your existing applications and tools. Multiple Amazon EC2 instances can access an Amazon EFS file system at the same time, allowing Amazon EFS to provide a common data source for workloads and applications running on more than one Amazon EC2 instance.
You can mount your Amazon EFS file systems on your on-premises datacenter servers when connected to your Amazon VPC with AWS Direct Connect. You can mount your EFS file systems on on-premises servers to migrate data sets to EFS, enable cloud bursting scenarios, or backup your on-premises data to EFS. Amazon EFS is designed for high availability and durability, and provides performance for a broad spectrum of workloads and applications, including Big Data and analytics, media processing workflows, content management, web serving, and home directories.
Amazon EFS Benefits
Seamless Integration - Amazon EFS provides a file system interface (using standard operating system file I/O APIs) and file system access semantics (such as strong data consistency and file locking). Amazon EC2 instances mount Amazon EFS file systems via the NFSv4.1 protocol, using standard operating system mount commands. You can also mount Amazon EFS file systems on your on-premises datacenter servers via the NFSv4.1 protocol when connected to your Amazon VPC with AWS Direct Connect.
Scale Up and Down Automatically - Amazon EFS automatically and instantly scales your file system storage capacity up or down as you add or remove files without disrupting your applications, giving you just the storage you need while reducing time-consuming administration tasks.
Fully Managed Service - Amazon EFS has a simple web services interface that allows you to create and configure file systems quickly and easily. The service manages all the file storage infrastructure for you, avoiding the complexity of deploying, patching, and maintaining complex file system deployments.
Share File Storage Access Across Instances - Multiple Amazon EC2 instances can access an Amazon EFS file system, so applications that scale beyond a single instance can access a file system. Amazon EC2 instances running in multiple Availability Zones (AZs) within the same region can access the file system, so that many users can access and share a common data source.
Consistent, Scalable Performance - Amazon EFS is designed to provide the throughput, IOPS, and low latency needed for a broad range of workloads. With Amazon EFS, throughput and IOPS scale as a file system grows, and file operations are delivered with consistent, low latencies.
Low Cost - Amazon EFS provides the capacity you need, when you need it, without having to provision storage in advance. You pay for what you use, with no minimum commitments or up-front fees.
Highly Available and Durable- Amazon EFS is designed to be highly available and durable. Each Amazon EFS file system object (i.e. directory, file, and link) is redundantly stored across multiple Availability Zones.
Secure - Amazon EFS allows you to tightly control access to your file systems through POSIX permissions. Use Amazon Virtual Private Cloud (Amazon VPC) to manage network access. Use AWS Identity and Access Management (IAM), to control access to Amazon EFS APIs.
How can I use Amazon Elastic File System ?
Enterprise Applications and Applications Delivered as a Service - Amazon EFS provides the scalability, elasticity, availability, and durability to be the file store for enterprise applications and for applications delivered as a service. Its standard file system interface and file system semantics make it easy to migrate enterprise applications to the AWS cloud or to build new ones.
Content Management and Web Serving - Amazon EFS can be used as a highly-available, high performance file system for content management systems that store and serve information for a range of applications like web sites, home directories, online publications, and archives.
