Amazon Elastic Block Store (EBS)
By John | August 21, 2008
Amazon now offers an opportunity to have persistent storage through their new EBS offering. Here are some features from the link…
Features of Amazon EBS volumes:
- Amazon EBS allows you to create storage volumes from 1 GB to 1 TB that can be mounted as devices by Amazon EC2 instances. Multiple volumes can be mounted to the same instance.
- Storage volumes behave like raw, unformatted block devices, with user supplied device names and a block device interface. You can create a file system on top of Amazon EBS volumes, or use them in any other way you would use a block device (like a hard drive).
- Amazon EBS volumes are placed in a specific Availability Zone, and can then be attached to instances also in that same Availability Zone.
- Each storage volume is automatically replicated within the same Availability Zone. This prevents data loss due to failure of any single hardware component.
- Amazon EBS also provides the ability to create point-in-time snapshots of volumes, which are persisted to Amazon S3. These snapshots can be used as the starting point for new Amazon EBS volumes, and protect data for long-term durability. The same snapshot can be used to instantiate as many volumes as you wish.
