1: we are paying (ballpark) 5-10k for our account. We have 5-10 domains on the enterprise plan, and we have roughly 100m requests per month plus about 70TB bandwidth, IIRC... Mind you, we have other sites that are on Pro ($20) or business ($200) plans and they are coming in at around a million requests a day (only about 2-3Gb a day) and no one complains.. could be the 5-10k we spend a month with them makes them think twice... Most of our cost is for the 24/7 tech support, regular meetings, etc. extra domains are a somewhat fixed cost (little over double a business plan domain) and that gives us extra features.
2: for Azure and BW Alliance, we were told you need to use a storage account and use "Internet Routing" not "Azure Routing" for the account. Azure routing is, IIRC, 12c per Gig. Internet routing is closer to 8c... Cant see an option for Servers, but I think Internet Routing might work for them too...
3: Any proof of this? I do know there is a limit of 256Mbyte for free account files, but not sure about what the limits on Pro or Business accounts...
4: https://cloudflare.net/news/news-details/2021/Cloudflare-Ann... Seems they spend nearly double on Sales and Marketing than they do on R&D... and they seem to be currently loosing money, but what startup doesn't lose money for the first few years?
