This slide shows all of the scaling discussed in the lecture so far. We distribute content to CDNs, cache the output of web servers, cache database objects in a key-value store, and shard the database.


Does the web browser create requests to both the page (load balancer at the server) and to CDNs to get media and consolidate the received data into the webpage.


@lol Good question - but how will the browser know which CDNs what requests to make the to the CDNs?


@eknight7 I think the web server will generate a proper url to the right CDN in the response web page
