Is EFS a file system?

AWS Elastic File System (EFS) is one of three main storage services offered by Amazon. It is a scalable, cloud-based file system for Linux-based applications and workloads that can be used in combination with AWS cloud services and on-premise resources.

What protocol does AWS EFS use?

Amazon EFS provides shared access to data using a traditional file sharing permissions model and hierarchical directory structure via the NFSv4 protocol.

Does AWS EFS support NFS?

AWS EFS supports NFS 4.0 and 4.1, but an important caveat is that NFS on Amazon only works with Linux instances (Amazon provides shared storage for Windows using a different service, Amazon FSx). Any Linux-based EC2 machine can mount a folder stored on EFS as a local drive, using NFS.

How do I view EFS files?

Sign in to the Amazon Web Services Management Console and open the Amazon EFS console at https://console.amazonaws.cn/efs/ . Choose File systems to display the list of file systems in your account.

Is EFS only for Linux?

Amazon EFS is compatible with all Linux-based AMIs for Amazon EC2. You can mix and match the instance types connected to a single file system. For a step-by-step example of how to access a file system from an Amazon EC2 instance, please see the instance type guide here.

Why do we use EFS?

Within its role as a shared file storage service for multiple EC2 instances, EFS provides many benefits: Adaptive throughput – EFS’s performance can scale in-line with its storage, operating at a higher throughput for sudden, high-volume file dumps, reaching up to 500,000 IOPS or 10 GB per second.

Is EFS faster than S3?

EBS and EFS are both faster than Amazon S3, with high IOPS and lower latency. EFS is best used for large quantities of data, such as large analytic workloads. Data at this scale cannot be stored on a single EC2 instance allowed in EBS—requiring users to break up data and distribute it between EBS instances.

Is EFS faster than EBS?

EBS and EFS are both faster than Amazon S3, with high IOPS and lower latency. EBS is scalable up or down with a single API call. Since EBS is cheaper than EFS, you can use it for database backups and other low-latency interactive applications that require consistent, predictable performance.

What is difference between EBS and EFS?

EBS is a high-performance per-instance block storage system designed to act as storage for a single EC2 instance. EFS is a highly scalable file storage system designed to provide flexible storage for multiple EC2 instances. It’s also useful for storing static html pages and shared storage for applications.

Is Amazon EFS only for Linux?

Why is Amazon EFS?

Amazon EFS is designed to provide massively parallel shared access to thousands of Amazon EC2 instances, and AWS containers and serverless compute services including Amazon Elastic Container Service (ECS), Amazon Elastic Kubernetes Service (EKS), AWS Fargate, and AWS Lambda, enabling your applications to achieve high …

What kind of file system does Amazon EFS support?

Amazon EFS supports the Network File System version 4 (NFSv4.1 and NFSv4.0) protocol, so the applications and tools that you use today work seamlessly with Amazon EFS.

Is the Microsoft EFS compatible with other operating systems?

Some EFS settings can also be mandated via Group Policy in Windows domain environments. Cryptographic file system implementations for other operating systems are available, but the Microsoft EFS is not compatible with any of them. See also the list of cryptographic file systems .

How is data organized in an EFS system?

An EFS is a Network File System (NFS) that organizes data in a logical file hierarchy. Data is stored in a path-based system, where data files are organized in folders and sub-folders.

Is the Amazon EFS compatible with Linux AMIs?
