AMI

Amazon Machine Image

Visibility

  • Public: Everyone can see and use them

  • Explicit: You can allow specific users to see them

  • Implicit: Private

This is not the same as publishing them to the AMI marketplace though.

Limits

  • EC2 has a limit on the maximum number of running instances per region.

  • There are a lot of limits, they can be viewed via EC2 -> Limits.

  • If needed you can ask AWS to raise the limits.

  • All AMIs are region specific

  • The max number of AMIs is 10'000 since they're using EBS snapshots.
