Amazon EC2 Spot now supports encryption of EBS volumes. Ec2 Spot will create encrypted EBS volumes at launch so you no longer have to boot from an encrypted snapshot or an encrypted AMI. To use this new feature, specify “Encrypted: true” as the encryption behavior within block device mappings, when submitting a Spot request. When you specify “Encryption:true”, Spot will encrypt the EBS volume at the launch time and create encrypted volumes. If you already have an encrypted EBS volume in use then specify the snapshot ID without the “Encrypted” flag and Spot will continue to create encrypted volumes in your existing encrypted EBS snapshot.
