> StackOverflow runs on a couple of servers. K8s can as well. The difference is a bunch of servers running k8s or a bunch of servers running custom code to duplicate parts of k8s.
Or a couple of servers running IIS with a handful of web apps, maybe a reverse proxy.

No it doesn’t. From your link: • 9 web servers • 4 SQL servers • 2 Redis servers • 3 tag engine servers • 3 Elasticsearch servers • 2 HAProxy servers That comes to 23. I know “a couple” is sometimes used to mean more than two, but… not that much more than two. “A couple” is just flat-out wrong; I’d guess that he’s misinterpreting ancient figures, taking the figures from no later than about 2013 about how many web ser…
Exactly. That twitter thread is just pure rage based on no data. Sum up resources from that page - we are talking around 6500GB* of RAM worth of servers. That is no homelab. * Maybe a bit more/less, because it's not clear to me if DB RAM is per server, or per cluster. Likely server, as on other servers. There is also no data on how big is their haproxy.
I love these Twitter takes. They say something to get attention but if you look at it for more than a second it's.. it's just nothing data Comparing a troubleshooting guide to running a site on a couple of servers is a bit too different for me. Compare it to a troubleshooting guide for those two servers, let's see how they stack up. No using any "ask {specific person}" either Don't get me wrong, kubernetes is overkil…
SO is relatively simple; it's basically customized forum software which is a solved problem that has been around for decades. A junior dev can build an alternative, and it can be built using tried and true solutions like MySQL + PHP, which are horizontally scalable with database sharding, read replicas, and maybe stuff like memcached to accumulate votes before updating the database or a CDN for caching static files.
Google has different problems and different workloads, and they have hundreds of times more applications with thousands of times more load. Apples and oranges.

aws elastic beanstalk all what a modern web app needs out of the box with 1 day to learn instead of years... and the best? you don't have to modify your code to work on it, ie environment and code are separate.
And if they don't like your politics, they simply pull the plug.
I mean these politics are pushed by rich Americans and foreign interests, surely they have the means to start their own hosting platform. It's the same that advocate in favor of businesses rejecting customers because of free market.

I don't think this really does justice to what Stack Overflow does. They're probably the most visited engineering-related site on any given day. They have their widely known Q&A, live updates and notifications, chat rooms, a blog, job listings with email updates, review queues, moderator tools, and so forth. Perhaps you only use three features, but the site does a tremendous amount, and that's not even thinking about…
Perhaps I was being a little dismissive but it doesn’t have the same features of something like Facebook or LinkedIn or google
I hate when stack overflow is held up as an example of how we can run any system on “a few servers” - stacknoverflow has like 3 features and has an engineering focus on the single goal of performance and keeping on running on the small subset of servers. Every other project as different constraints.
I think number of features have little to do with the situation. Nowadays, everybody insists on putting stuff on K8s regardless of how large or small it is. An application is an application for the purpose of running it on a server. It doesn't really matter how much functionality it has. It is microservices "revolution" (quotes intentionally) that caused larger applications to be split a lot of small ones and complic…
But if you already have the tooling, experience and support for k8s, why wouldn't you use it?
I can fire up a k8s cluster on any major cloud provider in minutes (or bare metal in slightly longer), and deploy almost any web app using a standard interface that has extremely wide adoption.
K8s supports a ton of things, but you don't have to use them. It can be complicated, but usually it's not.
It feels a bit like saying why use Linux for your simple app when it could run just fine on DOS or QNX. How many years of my life have I wasted debugging networking issues on Linux or Windows that turned out to be caused by a feature I wasn't even (intentionally) using...

It's taking one source - look at how these people solved it! - and trying to apply it to others.

> Google has different problems and different workloads
Which of these do you think most organisations most closely resemble?
I don’t think anybody would disagree if you said that you should use Kubernetes for organisations that resemble Google. But most organisations don’t look anything like Google. They look a lot more like Stack Overflow. So the “You don’t need this…” statement holds true for almost everyone.

https://stackexchange.com/performance
1.3 billion page views per month, 9 web servers, 4 sql servers
Stackoverflow is notable because they went down the C#/MVC/SQL Server route from the start, which meant much better performance per server. Thats why they make an interesting counterexample to the usual way...
