![]() But this requires a VPN connection to the cloud or using AWS Direct Connect, which gives you a private network link into your Amazon Virtual Private Cloud (VPC). When you use EFS, not only cloud machines can mount files as a local drive on-premise machines can do so too. You can allow on-premise machines to access cloud-based files via NFS Access to files is secured using POSIX permissions. Any Linux-based EC2 machine can mount a folder stored on EFS as a local drive, using NFS. Only Linux is supportedĪWS 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). The following are five things that are important to know before you implement EFS as your NFS access solution. 5 Important Considerations when Using EFS as an NFS Solution EBS has higher performance, but it is attached to a specific EC2 machine instance and cannot be shared across multiple machines. S3 does not support NFS.Ĭomparing EFS to another popular Amazon service, Elastic Block Storage (EBS), the major advantage of EFS is that it offers shared storage. An application can access files on EFS just like it would do in an on-premise environment. While Amazon S3 also offers shared storage, EFS provides higher performance and a file-system based model that doesn’t require changes to existing applications. It is scalable and elastic, supporting thousands of attached machines instances on EC2 with predictable performance. If you are running workloads on the Amazon cloud, Amazon Elastic File Service (EFS) is the solution you can use to provide users with NFS capabilities.ĮFS is a shared file system that can be accessed by machines running on Amazon EC2. Elastic File Service: The AWS NFS Solution While earlier versions of the protocol used User Datagram Protocol (UDP), from version 4.2 onwards NFS runs on top of Transmission Control Protocol (TCP). Features in the latest version of the protocol include server-side copying, application input/output (I/O) advise, sparse files, and application data blocks. NFS was developed in the 1980s and has gone through several versions the latest version NFSv4.2 (RFC-7862) released in 2016. NFS users can “mount” a portion of the file system on a server, and those files are designated as an additional drive in the user’s operating system and become accessible locally. Network File System (NFS) is a distributed file system protocol that allows users to access files over a network like they access local storage. NFS File Sharing with Cloud Volumes ONTAP.5 important considerations when using EFS as an NFS solution.Elastic file service - the AWS NFS solution.In this post, we’ll take a deep dive into AWS NFS, and show how NetApp Cloud Volumes ONTAP can address these considerations. In this blog post, we’ll look at 5 key considerations to address when using AWS EFS as your NFS solution, including operating system support, on-premise access to files, and managing backups. In this article, we’ll discover more about network file systems and see how AWS EFS, a popular cloud file sharing service, can provide you with NFS capabilities when you run workloads on the Amazon cloud. Network File System (NFS) is a distributed file system protocol that lets users access files over a network similar to the way they access local storage.
