As a result of the complexity and requirements, we realized we would like to have a solution for CDN, WAF, and DDOS protection with one vendor.
Depending on your definition of ddos protection Fastly has those things along with granular and semi scriptable configurability via vcl. Granted it’s been 2-3 years since I last did a comparison between Fastly and Cloudflare but I can’t understand why a company with presumably a need for configurability at the edge would make this choice. Cloudflare’s entry tiers are unbeatable in price but beyond that it’s extremely bulky.
