For an e-commerce application running on GKE clusters in the US and Europe with Cloud CDN, what is the best combination of GCP services to ensure seamless failover and low-latency access?

*The ideal combination for ensuring seamless failover and low-latency access for an e-commerce application deployed on GKE clusters in multiple regions (US and Europe), while using Cloud CDN, is the Global HTTP(S) Load Balancer with Multi-cluster Ingress and Cloud CDN. The Global HTTP(S) Load Balancer offers high-performance and efficient traffic distribution across multiple regions, ensuring low latency and high availability. Multi-cluster Ingress enhances this by facilitating seamless failover and unified management across clusters. Additionally, integrating Cloud CDN for content caching further improves latency and user experience by caching content close to users. Other options, such as internal load balancers, Traffic Director, or regional external load balancers, are either not suitable for a global setup or do not offer the combined benefits of multi-regional load balancing and content caching.*
