Hello Im using cloudflare DNS only, without any other caching/security. the great part is if Im under attack I just click a button, and that's it -- does moving to another DNS hosting like (AWS, Google, Azure, dnsimple.com) Adds any further speed of the website "our website has mild traffic"
From my understanding, the only speed advantage a DNS service provides is reduced server latency across the world. From my testing, Cloudflare performed better than Rackspace Cloud DNS and Namecheap Premium DNS. I have yet to try Amazom Route 53 and other services.
Amazon Route 53 is nice. I just moved everything off of CF over to R53. What do you mean by "Clicking a button"? If you're under an attack and you're just clicking a button then you're using their security. I used CF for awhile. The only thing I have an issue with is CF basically owning your security as it passes through their network. If they get a request from an authority to see all your traffic, they'll pipe that right through whatever authority wants the data. Added, some users have complained about CF and TOR, even after I added the necessary things to CF which makes it TOR compatible. CF is nice because it's free. R53 charges.
I mean I can enable the CF security immediately by login in into the CF and enable their security features to route the attacker away. (by adding a new security layer)
