EC2 - AMI

AMI = Amazon Machine Image

• AMI are 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)
