Can the majority of webapps run on a single machine? Probably. Do most of your customers expect close to 100% uptime? Yes. Does one machine provide the uptime required by your customers? Most definitely not.
A $5 VPS, with almost any app, can handle the front page of hacker news. If I remember correctly I'd even venture to say hacker news runs on a one or two core box. It should be the standard

Three machines get you availability that one machine can't.
That is not strictly true and entirely depends upon the machines in question.
I can confirm. I've had quite a few projects that made it to the front page of HN and handled the traffic like cake. All of them ran on 5$ digital ocean droplets. I accept some projects are more resource expensive than others, but majority of the time you can get away with a bit of asynchronous responses + scheduler/queue to spread the load horizontally over time. Unpopular opinion: I blame the new age devops culture…
The problem with devops replacing the old title “sysadmin” was that the dev part dragged in the worst thing about developer culture: the love of complexity and the tendency to build massive towers of it. Sysadmins usually avoided complexity because their attitude toward it was more sensible: it’s expensive, fragile, and tends to actually multiply failure modes. I also blame cloud marketing. This stuff is a gigantic m…

If you guys don't see the value of being able to click on a button on a website to deploy, perfectly, everytime over some guy sshing into the box and running git pull I dunno what to tell you.
Yes. You don't even need containers. Write your program as one Go executable and drive it from fcgi. Go is fast enough that you can get a lot of work done on a minimal server. Fgci provides "orchestration" of multiple processes, plus crash and restart handling. Also, there's much less attack surface. If your minimal Go program can only respond to specific requests, there's not the problem of an attacker targeting som…
