I am currently under the Pro plan and been testing with Cloudflare. We are planning to migrate our entire CDN from Cloudfront to Cloudflare. However, I have a few doubts:
When we migrate from Cloudfront to Cloudflare, initially the content will hit from our server (to Cloudflare). In such a scenario, it will burden the servers for the initial days. Is there a possibility to warm up the cache on Cloudflare? If yes, how?
Our usage on Cloudfront last month was approx 3200 GB on bandwidth and 125 million requests per month. Will the pro plan be able to support this? Or will Cloudflare limit any usage?
Best way to “warm the cache” is to hit it yourselves, however, with proper cache-control headers you should only receive one or two hits from a CF datacenter before it’s being served from cache. I’ve found that CF is really good at cache HITs, and you can see if Cache is working by reading the below article.
While I can’t guarantee this, Cloudflare generally is fine with that request volume on paid plans, but may ask you to upgrade to Business if your domain is causing too much strain on their network. The best course of action would be to open a support ticket with these traffic stats and they will be able to give you a better, more definitive answer.
