    They have details here: https://nickcraver.com/blog/2016/02/17/stack-overflow-the-ar... Lots of caching, lots of RAM, SSD storage, and a low-level ORM for SQL.

    https://stackexchange.com/performance https://nickcraver.com/blog/2016/02/17/stack-overflow-the-ar... Lots of caching (redis, CloudFlare) and trying not to use the database unless absolutely necessary, I would expect.

    Ah the old cloud provider switcheroo. Yip this is the way they make money. They make it easy to setup some gigantic hugely scalable website then hit you with a gigantic scaled up bill. AWS would do this as well. Team I'm in at the moment is in the early stages of cloud adoption but the company in total has fell hook line and sinker for AWS. When I mentioned the cost there is always an excuse. The main one being that…

    A better example might be stack overflow that ran on four(?) boxes for a long while (two sql server s, two iis/dot.net application/web servers). They now have a few more bits: https://nickcraver.com/blog/2016/02/17/stack-overflow-the-ar...

    For people who enjoyed this post but want to see the other side of the spectrum where self hosted is the norm I'll point to the now classic series of posts on how Stack Overflow runs its infra: https://nickcraver.com/blog/2016/02/17/stack-overflow-the-ar... If anyone has newer posts like the above, please reply with links as I would love to read them.

    > On the other hand, do we really want a handful of unelected billionaires deciding what is acceptable speech - whether or not we agree with them? We talk about net neutrality, but shouldn't we apply the same standard to hosts like AWS? And what did start-ups do before AWS et al ? Didn't they 'just': rent a rack, fill it with computers, get an ASN/IP block, and make it accessible by DNS? I understand it's more 'agil…

    Apparently HackerNews used to run from a single application server + Cloudflare caching, but later moved away from Cloudflare. Unsure how many web servers it runs on now. [0] In 2016, Stack Overflow ran on 11 IIS web servers, but they really only needed 1.

    > StackOverlow is a small website that can run in a garage on a couple of servers, and that's with a lot of margin. Maybe things have changed, but in 2016 they were running three or four dozen servers in each of two data centers: https://nickcraver.com/blog/2016/03/29/stack-overflow-the-ha...

    > the biggest one is db.r5.24xlarge with 48 cores and 768 gb ram. I imagine that can take you quite a long way--perhaps even into millions of users territory That will run Stackoverflow's db by itself for reference, along with sensible caching (they're very read-heavy and cache like crazy).

    StackOverflow is known to operate their own servers on their own datacenters and as far I recently read, they are still tuning with no container tech. https://nickcraver.com/blog/2016/05/03/stack-overflow-how-we...
