Use Cloudflare as a unified control plane in front of your multi-cloud infrastructure. We don't just use it for DNS and caching; it acts as our primary API Gateway and Web Application Firewall (WAF). By routing all traffic through Cloudflare, we get robust DDoS mitigation and can easily load-balance or route requests to the appropriate services running on AWS, GCP, or Azure. This simplifies our architecture, enhances security for our React single-page application and Spring Boot backend, and reduces latency for our users globally, all from a single dashboard.
