Amazon EC2 and Persistent Storage

Amazon announces that they will have support for persistent storage in an upcoming release. Right now it is being used privately by a handful of EC2 users.

This new feature provides reliable, persistent storage volumes, for use with Amazon EC2 instances. These volumes exist independently from any Amazon EC2 instances, and will behave like raw, unformatted hard drives or block devices, which may then be formatted and configured based on the needs of your application. The volumes will be significantly more durable than the local disks within an Amazon EC2 instance. Additionally, our persistent storage feature will enable you to automatically create snapshots of your volumes and back them up to Amazon S3 for even greater reliability.

You will be able to create volumes ranging in size from 1 GB to 1 TB, and will be able to attach multiple volumes to a single instance. Volumes are designed for high throughput, low latency access from Amazon EC2, and can be attached to any running EC2 instance where they will show up as a device inside of the instance. This feature will make it even easier to run everything from relational databases to distributed file systems to Hadoop processing clusters using Amazon EC2.

This is an exciting announcement and soon there will be no reasons why you wouldn’t use EC2 for a production system.  The other big thing was the dynamic IP addresses, but that was addressed a couple weeks ago with the Elastic IP Addresses.
