in the cloud you should be able to turnkey this quite easily. i think in a DC this can be a bit more tricky because you will still be getting traffic from the DOS to your network interface after you have flipped the switch to cloudflare. This traffic will cause both you and your provider a problem. but i think the idea is you would have two sets of IPs one for the normal public hosting, and one for cloudflare proxy then when you become under DOS attack you have a process in place for BGP to stop advertising the normal public hosting IPs and you switch to cloudflare. i presume if BGP stops advertising the IPs then eventually you will stop getting the DOS traffic.
