• AMI = Amazon Machine Image

• AMIs are a customisation of an EC2 Instance

  • You add your own software, configuration, OS, monitoring etc

  • Faster boot/configuration time because all your software and config is pre-packages

• AMIs are built for a specific region (and can be copied across regions)

• You can launch EC2 instances from

  • Your own AMI: uyou make and maintain them yourself

  • An AWS Marketplace AMI: an AMI someone else made (and potentially sells)
