Summary

Completed

Azure Content Delivery (CDN) Network is a powerful way to improve performance and increase user satisfaction with websites that serve primarily large static files to a global audience. The ability to cache large video and audio files and web pages more locally to the user than the origin server, reduces the load on the origin server and minimizes latency.

Clean up

The sandbox automatically cleans up your resources when you're finished with this module.

When you're working in your own subscription, it's a good idea at the end of a project to identify whether you still need the resources you created. Resources that you leave running can cost you money. You can delete resources individually or delete the resource group to delete the entire set of resources.

Check your knowledge

1.

If a CDN doesn't have a copy of a user-requested file in an edge server at a Point of Presence (POP), what happens next?

The edge server checks with other edge servers at the same POP. If the file is still not present, it then requests the file from the origin server, returns the file to the user and caches the file.

The POP passes the request to the next closest POP.

The POP replies with a File not Found message.
