EBS Volumes Facts

  • When you create an EBS volume in an Availability Zone, it is automatically replicated within that zone to prevent data loss due to a failure of any single hardware component.

  • An EBS volume can only be attached to one EC2 instance at a time.

  • After you create a volume, you can attach it to any EC2 instance in the same Availability Zone.

  • An EBS volume is off-instance storage that can persist independently from the life of an instance.

  • EBS volumes support live configuration changes while in production which means that you can modify the volume type, volume size, and IOPS capacity without service interruptions.

  • EBS encryption uses 256-bit Advanced Encryption Standard algorithms (AES-256).

  • EBS Volumes offer 99.999% SLA.
