Design tested failover, consistent edge policy, and recovery objectives. - [China CDN and ICP](/en/guides/china-cdn-icp-rollout.md): Understand when Mainland China hosting or CDN delivery introduces ICP requirements, how China DNS and Cloudflare China Network work, and how to plan a phased rollout. - [Unified Incident Timeline](/en/guides/unified-incident-timeline-cdn-waf-dns-origin.md): Correlate CDN, WAF, DNS, bot, DDoS, and origin evidence into a defensible incident timeline with provenance, confidence labels, privacy controls, and an SRE workflow. - [E-commerce Edge Architecture](/en/guides/ecommerce-edge-architecture.md): Design an ecommerce edge that caches public catalog content safely, keeps account and checkout state private, protects origins, and applies layered bot defense. - [CDN Cost Optimization](/en/guides/cdn-cost-optimization.md): Model CDN delivery, request, origin, shielding, and observability costs. Measure byte offload and cache fragmentation before changing policy. - [Media Edge Architecture](/en/guides/media-edge-architecture.md): Design a publisher edge for breaking-news spikes, public caching, paywalls, ad-tech resilience, image delivery, crawler access, and origin protection. - [Video Streaming at the Edge](/en/guides/video-streaming-at-the-edge.md): A practical guide to HLS and DASH manifests, segment caching, range requests, origin shielding, ABR, entitlement boundaries, QoE observability, and safe rollouts. - [HTTP/3 and QUIC](/en/guides/http3-quic-production-websites.md): Deploy HTTP/3 and QUIC safely with UDP fallback, TLS 1.3, 0-RTT replay controls, proxy considerations, protocol observability, and production validation. - [Kubernetes Multi-Region Edge](/en/guides/kubernetes-multi-region-edge.md): Design a Kubernetes multi-region architecture with data consistency, traffic steering, health checks, regional failover rehearsals, and end-to-end latency measurement. - [Edge Compute Architecture](/en/guides/edge-compute-architecture.md): Design edge compute architecture with provider-neutral edge design: safe cache keys, origin controls, edge state boundaries, observability, and portable patterns. - [Global Edge Architecture](/en/guides/global-edge-architecture.md): Plan a global edge architecture with safe DNS and traffic steering, cache and origin design, regional failure tradeoffs, observability, and provider-neutral resilience. - [Deploy Cloudflare Workers](/en/guides/cloudflare-workers-deployment.md): A production Cloudflare Workers deployment workflow, from edge-fit assessment through edge canary rollout, Workers observability, and rollback. - [Fastly Compute Deployment](/en/guides/fastly-compute-deployment.md): A practical, verified guide to Fastly Compute deployment: reproducible WebAssembly edge packages, explicit service configuration, secret handling, local and staged testing, observability, and a tested Compute rollback path. - [Fastly Origin Shielding](/en/guides/fastly-origin-shielding.md): Configure Fastly origin shielding safely by choosing a shield near each origin, assigning it per backend, verifying cache-miss behavior, monitoring logs and headers, and retaining a rollback path.
