亚马逊发布了EC2的持久存储EBS(Elastic Block Store)。

自从使用EC2以来,应用跑在instance上,总是担心重启后会丢掉数据,中途也使用过PersistentFS来持久到S3上,但是毕竟不是官方的方法,这次官方发布了EBS,就可以帮忙解决很多问题。

Amazon EBS volumes can be created in any size between 1 GB and 1 TB, and multiple volumes can be attached to a single instance.

Dear AWS Developer,

We are pleased to announce the release of a significant new Amazon EC2 feature, Amazon Elastic Block Store (EBS), which provides persistent storage for your Amazon EC2 instances. With Amazon EBS, storage volumes can be programmatically created, attached to Amazon EC2 instances, and if even more durability is desired, can be backed with a snapshot to the Amazon Simple Storage Service (Amazon S3).

Prior to Amazon EBS, block storage within an Amazon EC2 instance was tied to the instance itself so that when the instance was terminated, the data within the instance was lost. Now with Amazon EBS, users can chose to allocate storage volumes that persist reliably and independently from Amazon EC2 instances. Amazon EBS volumes can be created in any size between 1 GB and 1 TB, and multiple volumes can be attached to a single instance. Additionally, for even more durable backups and an easy way to create new volumes, Amazon EBS provides the ability to create point-in-time, consistent snapshots of volumes that are then stored to Amazon S3.

Amazon EBS is well suited for databases, as well as many other applications that require running a file system or access to raw block-level storage. As Amazon EC2 instances are started and stopped, the information saved in your database or application is preserved in much the same way it is with traditional physical servers. Amazon EBS can be accessed through the latest Amazon EC2 APIs, and is now available in public beta.

For more information on Amazon EBS and detail on how to start using this feature, please see the resources listed below:

We hope you enjoy this new feature and we look forward to your feedback.

Sincerely,

The Amazon EC2 team

EBS是指直接在Storage上划出一个空间,用来存储数据吗?应该没有虚拟化的概念在里面吧?

有人用过ec2吗?个人觉得太贵了,用不起

不知道咱们国内现在还是不是在观望中。
