AMI

A deep dive into AMI - Practical ver.



What is AMI (Amazon Machine Image)?

  • A complete backup of an EC2 Instance
  • Costs are incurred based on the EBS capacity that contains the AMI backup
    • EBS Volume has a Snapshot
      • A Snapshot is a backup of the disk only!
  • Snapshots are stored in S3
    • Stored in S3 managed by AWS
    • They use incremental backup
      • Just like docker images...
      • So the second backup is faster!
