Back-of-the-envelope estimation

Turn users into requests per second, storage and bandwidth before drawing anything: 10 million daily users making 20 requests is about 2,300 requests per second on average and several times that at peak.

Where it shows up in real systems

    In production: Web browsers, iOS and Android apps, Partner APIs
