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!
