i just wanted to know how many servers Stack Overflow runs on, with 240,000 users on the site, im thinking they have 1,000 of servers? but i wondered if you guys knew
That would be one server for each 240 people.. It's a bit overkill don't you think?
Servers can handle several connections per second; I'm not sure about the stack overflow architecture, but I work for a website where we have a bit over 11 million pageviews per month, and we have only 4 servers: two web servers for dynamic files, one for static files, and one db server.
That's also slightly outdated information. That is discussing The OR datacenter we are moving out of.
In the new DC we are running:
- 10 Window 2008 Webservers on Dell R610's
- 2 windows DB servers on Dell R710s
- 2 HA Proxy load balencers
- A pair of Dell Servers Running Ubuntu acting as routers.
- A few backend management server - backup, monitoring, etc.
If your are interesting in our infrastructure Kyle and I talk about it on The serverfault blog
Lots of useful information (and links) can be found in this elaborate answer.
ThinkServer RS110 1U - web tier (x6 - two host Stack Overflow) ThinkServer RD120 2U - database tier (x2 - one primary, one backup)
So that's 8 instead of 1000. You might have overestimated (a bit).
