Why the models rank Amazon CloudFront — on best cdn platforms for low-latency api delivery
“Excellent value for AWS-hosted APIs through the AWS backbone, Origin Shield, granular cache and origin policies, CloudFront Functions, Lambda@Edge, mature security integrations, and predictable flat-rate options”
Why the models rank Fastly — on best cdn platforms for low-latency api delivery
“Built for dynamic/API traffic rather than static cache hits—Instant Purge (~150ms global), origin shield, VCL + Compute (Wasm) with sub-ms cold starts and tight p99 on short request-path work (auth, routing, assembly). Lowest NA metro TTFB in 2026 probes; near-tie with Cloudflare if your users are APAC-heavy or you need a full app platform, not just delivery. Assumption: team will use edge logic and short-TTL/surrogate-key caching, not only a dumb reverse proxy.”
