AWS EFS 和 S3 之间有什么区别? [英] What is difference between AWS EFS and S3?

问题描述

AWS 本周发布了新的弹性文件系统.请参阅 http://aws.amazon.com/efs/该页面不包含很多细节.我想知道它与 S3 相比的性能以及其他差异.

AWS releases new Elastic File System this week. See http://aws.amazon.com/efs/ The page doesn't contain many details. I'd like to know its performance comparing to S3, as well as other differences.

推荐答案

如前所述，EFS 与 S3 完全不同.最简单的看待方式就是看底层技术是什么.

As already mentioned EFS is completely different to S3. The simplest way to look at is to look at what the underlying technology is.

S3 是一个对象存储，意思是它是一个更高层的数据存储系统，本质上它是一个数据库blob"存储，将数据作为对象存储在底层的简单数据库中.它专为一次写入读取多次访问而设计，非常适合图像或视频等媒体数据，特别是因为它是分布式的，并且提供了非常高的冗余度.

S3 is an object store, meaning it is a higher layer data storage system, essentially it is a database "blob" storage, storing data in an underlying simple database as an object. It's designed for Write once Read many access, perfect for media data like image or video particularly as it is distributed and offers a very high level of redundancy.

EFS 是一个网络存储系统，它的底层是一个存储阵列 (SAN)，它为多会话网络文件系统 (NFS) 提供标准协议它建立在高速 SSD 驱动器上，用于 ec2 实例的共享存储，想想文件服务器.AWS 和 IMO 已经有很长一段时间了，这是 aws 真正成为本地企业数据中心的竞争对手所缺少的最大关键组件之一.

EFS is a Network Storage system, underlying it is a storage array (SAN) and it offers the standard protocol for multi session network file systems (NFS) It's built on high speed SSD drives and is intended for shared storage for your ec2 instances, think file servers. It's been a long time coming for AWS and IMO this was one of the biggest missing key components for aws to really be a competitor to on-premise enterprise data centers.

EFS 的性能将是可扩展的，虽然我还没有看到详细信息，但我确信它可以像 EBS 一样支持预置 IOPS.

Performance for EFS will be scalable and although I have not seen the details yet I am sure it will allow for provisioned IOPS just like EBS.
