On-premise solutions are limited by your own bandwidth.  Attacks have been
publicly reported at 400Gbps, and are rumored to be even larger.  If you
don't have that much network to spare, then packet loss will occur upstream
of your mitigation.  Having a good relationship with your network
provider(s) can help here, of course.

If you go with a cloud-based solution, be wary of their SLA.  I've seen
some claim 100% uptime (not believable) but of course no refund/credits for
downtime.  Another provider only provides 20Gbps protection, then will
null-route the victim.

Live-fire is the cheapest approach (just requires some creative trolling)
but if you want to control the "off" button, cloud VMs can be tailored to
your needs.  There are also legitimate companies that do network stress

Keep in mind that you need to test against a variety of attacks, against
all components in the critical path.  Attackers aren't particularly
methodical, but will still randomly discover any weaknesses you've
