AMI - region

• AMI

  • Amazon Machine Image
  • a customization of an EC2 instance
    • You add your own software, configuration, operating system, monitoring…
  • Faster boot / configuration time because all your software is pre-packaged
• AMI are built for a specific region (and can be copied across regions)
• You can launch EC2 instances from:
  • A Public AMI: AWS provided
  • Your own AMI: you make and maintain them yourself
  • An AWS Marketplace AMI: an AMI someone else made (and potentially sells)

---

AMI Process

1. Start an EC2 instance and customize it
2. Stop the instance (for data integrity)
3. Build an AMI – this will also create EBS snapshots
4. Launch instances from other AMIs
