How AutoSpotting works

AutoSpotting makes it easy to adopt Spot instances in existing AutoScaling groups, without any changes to their launch template or launch configuration.

Once installed in minutes using CloudFormation or Terraform, you just need to tag your AutoScaling groups with "spot-enabled", set to "true".

AutoSpotting will take over such tagged groups and gradually replace their instances with similar or bigger Spot instances.

Here you can a little video that explains it in more detail.
