Elastic Compute Cloud (EC2)

Elastic Block Storage (EBS)

For most of its life in beta, EC2 offered only two kinds of storage, AMI based transient storage and S3. The transient storage was mounted as a filesystem and S3 was used for backup. To save data during downtime for instances, data had to first be saved off to S3 and the instance brought down. When the instance was brought back up, data was restored from S3. It was a painful process.

Enter EBS, the Elastic Block Store.

Have you been wondering what the differences between S3 and EBS are? I recently gave a high level overview of S3 and I plan to do one on EBS. I also plan to follow with a detailed looked at both S3 and EBS.

In the meantime, Cloudiquity has posted an entry, Differences between S3 and EBS. This is a nice overview. It provides some excellent technical details as well as some pricing info. Well worth a read.
