Not Specified

Controls key pair behavior at the blueprint level rather than the reservation level.

Auto-Generated per Business Group

Every machine provisioned in the same business group has the same key pair, including machines provisioned on other reservations when the machine has the same compute resource and business group. Because key pairs generated this way are associated with a business group, the key pairs are deleted when the business group is deleted.

Auto-Generated per Machine

Each machine has a unique key pair. This is the most secure method because no key pairs are shared among machines.

Specific Key Pair
