If you want to create an instance that uses ephemeral storage, meaning the instance data is lost when the instance is deleted, then choose one of the following boot sources:

  • Image: This option uses an image to boot the instance.
  • Instance Snapshot: This option uses an instance snapshot to boot the instance.
  • If you want to create an instance that uses persistent storage, meaning the instance data is saved when the instance is deleted, then select one of the following boot options:

  • Image (with Create New Volume checked): This options uses an image to boot the instance, and creates a new volume to persist instance data. You can specify volume size and whether to delete the volume on deletion of the instance.
  • Volume: This option uses a volume that already exists. It does not create a new volume. You can choose to delete the volume on deletion of the instance. Note: when selecting Volume, you can only launch one instance.
  • Volume Snapshot: This option uses a volume snapshot to boot the instance, and creates a new volume to persist instance data. You can choose to delete the volume on deletion of the instance.
