# Global Delivery Guides

Plan resilient worldwide delivery, routing, and data-aware traffic management.

- [Multi-CDN Explained](/en/guides/multi-cdn-strategy.md): Learn when a Multi-CDN architecture is justified, how to steer traffic safely, and how to test failover without creating cache or security gaps.

- [DNS Performance Guide](/en/guides/dns-performance.md): Understand DNS lookup latency, recursive caching, authoritative DNS, Anycast, TTLs, DNSSEC, measurement, migration, and rollback for faster websites.

- [CDN Migration Guide](/en/guides/cdn-migration.md): A step-by-step CDN migration plan covering configuration parity, DNS, TLS, cache behaviour, observability, staged cutover, and rollback.

- [Website Resilience](/en/guides/website-resilience.md): Assess whether multi-CDN reduces delivery risk. Design tested failover, consistent edge policy, and recovery objectives.

- [Hreflang and CDN Routing](/en/guides/hreflang-cdn-routing.md): How to combine hreflang with predictable CDN routing so search engines discover the right locale and users receive fast, correct content.

- [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.

- [CDN Data Residency](/en/guides/global-cdn-data-residency-sovereignty.md): Evaluate CDN and edge data residency, transfers, logs, security telemetry, processor controls, and exit plans without mistaking an EU region for a compliance conclusion.

- [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.

- [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.

- [Cloudflare Load Balancing](/en/guides/cloudflare-load-balancing.md): Configure Cloudflare Load Balancing pools, origin health checks, steering, session affinity, and failover with capacity-aware testing, observability, and explicit rollback criteria.
