QuestionQ361

Designing and planning a cloud solution architecture

Your company runs a global e-commerce application deployed on Compute Engine instances across multiple regions. Users access the application from around the world. You need to route users to the closest region, provide SSL termination, integrate with a CDN, and support backend autoscaling. Which load balancing solution should you choose?

  • A SSL Proxy Load Balancer
  • B Global External HTTP(S) Load Balancer
  • C Regional External Network Load Balancer (TCP/UDP)
  • D Regional Internal TCP/UDP Load Balancer
Explanation

A global external Application Load Balancer provides a single global anycast frontend, routes HTTP(S) requests to suitable regional backends, terminates TLS, integrates with Cloud CDN, and supports autoscaled instance-group backends. The proxy and regional network load balancers do not provide this complete HTTP(S), CDN, and global-routing combination.
