Inside the course
Trace a request from name resolution to a backend service. Compare routing and traffic-distribution roles, consider data transfer, and examine how zones and edge delivery affect an application's architecture.
Try this learning exercise
Sketch the path from a user's browser to a web application using DNS, a CDN, a load balancer and private servers. Label where traffic is filtered and where a component failure could interrupt the request.
