Confusion surrounding Cloudflare X Backblaze "Bandwidth Alliance" and free egress with CDN
Hi All
I'm a bit confused surrounding the nature of the Cloudflare and Backblaze B2's relationship and how this whole "free egress" with CDN works.
According to "Deliver Public Backblaze B2 Content Through Cloudflare CDN" it states that "you can store content with Backblaze B2 Cloud Storage and serve it to users using Cloudflare's CDN (Content Delivery Network) with no download fees from Backblaze". Which sounds amazingly sweet however I'm a bit confused in regards to the no download fees "from Backblaze" part. It sounds like I'll still be getting charged fees from Cloudflare? Is this the case? I've tried looking online and maybe I don't have the right search terms but I can't find any sort of pricing regarding this it sounds like it's completely free?
My use case is a large Backblaze B2 bucket serving between 1GB - 100GB to my personal server per day. Currently I'm biting the B2 download egress fees but this sounds like a way out if I'm understanding correctly.

Cloudflare's self-serve plans (Free/Pro/Business) do not have any bandwidth/egress costs.
That is very amazing. Just to confirm (apologies I've lost money on similar things from different services in the past so I just like quadruple clarify) if I set up my, for example, rclone mount connected to the B2 via Cloudflare CDN (I've checked the docs and they have a feature for this) I would incur zero egress fees from Cloudflare? Are there API fees? Do I get charged per call (lets say 10k class B transactions/day)?
Cloudflare has per-request fees if you use Cloudflare Workers, which is outlined here https://developers.cloudflare.com/workers/platform/pricing/
If the use-case doesn't use Workers, then there are no fees from Cloudflare. If you want to make sure you're not being charged anything from Cloudflare, you can always just not add a payment method.
Backblaze B2 themselves have per-request pricing that they charge for: https://www.backblaze.com/cloud-storage/transaction-pricing
Perfect. Thank you!
