Growth TikTok Shop API Network Architecture spans five network layers—edge CDN, DMZ, distribution, compute, and data—handling up to 5000 concurrent users across AWS, Azure, and GCP services. Traffic flows from internet users through CloudFront/Cloud CDN/Front Door WAF protection, then load balancers route requests to auto-scaling NestJS backend instances, Redis cache, and PostgreSQL replicas in isolated VLANs. The architecture isolates public edge (VLAN 10), distribution (VLAN 20), application compute (VLAN 30), and private data (VLAN 40) layers with internal firewalls, VPN admin access, and async video transcoding queues. This multi-cloud design demonstrates defense-in-depth segmentation, high availability through read replicas and auto-scaling, and secure secrets management critical for e-commerce platforms. Fork and customize this diagram on Diagrams.so to adapt CDN providers, add region failover, or integrate your recommendation engine specifics. The architecture balances performance (edge caching, Redis), security (WAF, internal firewalls, secrets vault), and operational resilience (async transcoding, staging PostgreSQL, centralized monitoring).
