How does a backend service differ from a backend bucket?

A backend service routes traffic to compute resources like VM instances or instance groups, while a backend bucket serves static content from a Cloud Storage bucket.

beginner

Why are health checks important for backend services?

Health checks monitor the status of backend instances to ensure traffic is only sent to healthy, responsive resources, improving reliability and user experience.

intermediate

Can a backend bucket be used with HTTPS load balancing?
