You have to put limitations on both sides. Just because the external
service (such as the DB) protects itself from ddos (accidental or not)
doesn't mean that applications don't have to be well behaved and limit the
pressure they put on the service. In fact - in a lot of cases - the
protection you are talking about is that the service will just outright ban
your IP (in less severe cases, it will just return a failure which will be
a lot more awkward to handle than if you made your app well-behaved). This
is something you have to avoid at app level.
