Correct. Putting the constraints on the machines is equivalent to doing: juju add-machine --constraints mem=4gb juju deploy mysql --to $MACHINE
Rather than doing: juju deploy mysql --constraints mem=4gb Constraints on an Application will affect all new units of an application, but constraints on a single machine only effect provisioning that machine.
