This makes sense. Thank you for the quick reply.

After I have instantiated the template, can the "temporary" image &
template be deleted, so as not to "clutter" the infrastructure.
(Specifically, so that neither is accidentally used in the future). Or
do both need to continue to exist in order for the VM to function
