I've been asked to size a web architecture for an excessive number of concurrent users ( hundreds of thousands ).

I'm having a hard time convincing these people that unless you are in the top 5 of your country websites it's quite hard to hit those numbers.

Can anyone provide some real world case studies providing stats for total / concurrent users explaining what is the usual ratio between total vs concurrent?

When I look at the Audience Overview report for the same day (hourly breakdown), the number of users shown for the 10AM hour is over 1000. I'm sure this has to do with… >>> More
