Fastly gives you VCL, Wasm compute, origin shielding and 150ms global purge at $0.12/GB plus $20 per TLS domain. CDNShark gives you declarative rules at $0.02/GB with certificates included. A comparison of purge design, cache tiering and what each model costs.

CDNShark vs AWS CloudFront: Pricing Models and the Missing Mid-Tier
CloudFront pay-as-you-go runs $0.085/GB plus request fees; its flat-rate plans start at $15/month with 50TB included. A look at both models against CDNShark's, plus the architectural difference that matters most: regional edge caches and Origin Shield.

CDNShark vs Bunny CDN: Where Bunny Wins, and Where the Products Diverge
Bunny is cheaper per gigabyte and has 119 PoPs to CDNShark's 11. Here is the honest cost table, how Bunny's two-tier network compares to CDNShark's weighted edge pool, and what bundled anycast DNS and private origin tunnels change.

CDN with a Private Origin Tunnel: Serving an Origin With No Public IP
The origin dials out; nothing dials in. How the tunnel ID rides in the TLS SNI to keep edges stateless, why authorisation is the mTLS client certificate and never the tunnel ID, why the connector needs no root, and why 523 must never be 502.
