Reference Architecture Diagrams

Reference architecture for deploying a multi-vendor approach to application security and performance. Covers active-active proxy configurations, multi-vendor DNS setup options (primary/secondary, dual-primary, hidden primary), routing considerations, configuration sync via Terraform/API, and origin connectivity patterns (Internet, tunnel/VPN, direct/CNI). Based on official Cloudflare reference architecture documentation.

Comprehensive Secure Access Service Edge (SASE) architecture combining Cloudflare Zero Trust (Access, Gateway, Browser Isolation, CASB) with network services (Magic WAN, Magic Transit) for a complete cloud-delivered security and networking platform.

Complete ZTNA architecture with Cloudflare Access, identity provider integration, device posture checks, and application access policies. Shows both browser-based and non-HTTP application access patterns.

Full-stack application architecture on the Cloudflare Developer Platform. Shows Workers for compute, D1 for SQL, KV for key-value, R2 for object storage, Queues for async processing, and Durable Objects for coordination.

End-to-end DNS resolution architecture showing split delegation between Cloudflare DNS and Azure DNS, CNAME-based routing to Azure Traffic Manager for active/standby failover, Terraform-synced zone management, and HTTPS traffic flow through Cloudflare Edge to origin. Demonstrates a real-world multi-vendor DNS + CDN pattern with health-check-based failover.

Comprehensive DDoS mitigation architecture showing how Cloudflare handles volumetric (L3/L4) and application-layer (L7) attacks. Includes Magic Transit for network-layer protection and WAF/rate limiting for application-layer defense.

Reference architecture for building a Retrieval-Augmented Generation (RAG) pipeline on Cloudflare. Uses Workers AI for inference, Vectorize for vector search, R2 for document storage, and D1 for metadata.

Cloudflare Gateway architecture for DNS filtering, HTTP inspection, and egress traffic control. Includes WARP client deployment, split tunnel configuration, and policy hierarchy.

End-to-end request flow through Cloudflare WAF managed rules, custom rules, and Bot Management scoring. Shows how requests are evaluated at the edge before reaching the origin, including challenge pages and JavaScript detections.

Network-layer DDoS protection with Magic Transit. Covers BGP prefix announcement, GRE/IPsec tunnel setup, health checks, traffic steering, and integration with Magic Firewall for packet-level filtering.

Architecture for protecting APIs with Cloudflare API Gateway, API Shield schema validation, mutual TLS (mTLS), and sequence mitigation. Covers both REST and GraphQL API patterns.

Architecture combining Cloudflare Browser Isolation with CASB for SaaS application control. Shows how risky web sessions are isolated and how shadow IT is discovered and governed.

Architecture for replacing traditional SD-WAN with Cloudflare Magic WAN. Shows branch office connectivity, data center interconnection via CNI, and policy-based routing across the Cloudflare network.

Cloudflare Area 1 email security deployment architecture. Covers MX record, inline, and API deployment modes. Shows phishing detection, BEC protection, and integration with Microsoft 365 and Google Workspace.
