Last week I received an email from Amazon indicating that their new persistent storage offering may be released to the public in a matter of days.
Several blogs are also reporting that Amazon's Elastic Block Store (EBS) is about to go live. From the various posts the service seems to be aimed at simple VM attached storage volume. These volumes can be thought of as raw, unformatted disk drives which can be formatted and then used as desired (or even used as raw storage if you'd like). Volumes can range in size from 1 GB on up to 1 TB; you can create and attach several of them to each EC2 instance. They are designed for low latency, high throughput access from Amazon EC2. Needless to say, you can use these volumes to host a relational database.
I can't wait to try this out. For some unknown reason, we haven't been invited into the beta, so like everyone else we will be eagerly awaiting access.
Here's the original email.
