Storing AWS Credentials on an EBS Snapshot Securely

July 19, 2010

Thanks to reader Ewout and his comment on my article How to Keep Your AWS Credentials on an EC2 Instance Securely for suggesting an additional method of transferring credentials: via a snapshot. It’s similar to burning credentials into an AMI, but easier to do and less prone to accidental inclusion in the application’s AMI. Read [...]

Creating Consistent Snapshots of a Live Instance with XFS on a Boot-from-EBS AMI

January 17, 2010

Eric Hammond has taught us how to create consistent snapshots of EBS volumes. Amazon has allowed us to use EBS snapshots as AMIs, providing a persistent root filesystem. Wouldn’t it be great if you could use both of these techniques together, to take a consistent snapshot of the root filesystem without stopping the instance? Read [...]

In this article I present a more flexible technique that uses an EBS snapshot instead. Update [...]

July 15, 2009

ElasticFox’s tags are stored locally within Firefox, so if you use ElasticFox from more than one browser your tags from one browser are not visible in any other browser. In this article I demonstrate how to copy [...]

Boot EC2 Instances from EBS

July 14, 2009

EBS offers the ability to have a “virtual disk drive” whose lifetime is independent of any EC2 instance. You can attach EBS drives to any running instance, and any changes made to the drive will persist even after the instance is terminated. You can also set up an EBS drive to be the root filesystem [...]
