> I find it much more appealing to just make the whole thing run on one fast machine. Indeed. Lots of examples out there, one being Let's Encrypt[1] who run off one MySQL server (with a few read replicas but only one write).

That doesn't really seem like an example, since the whole thing doesn't run one machine. The database alone has multiple machines.

  > That doesn't really seem like an example, since the whole thing doesn't run one machine. It is an example. It shows you how you can run a service that issues a few hundred million SSL certs a year off relatively few pieces of hardware, i.e. no need to go drinking the cloud Kool aid. There will never be a "perfect" example. The overall point here is demonstrating that the first answer to everything doesn't have to include the word "cloud". > The database alone has multiple machines. As I said, and the blog says ... there is only one writer. The other nodes are smaller read replicas. Which again shows you don't need to go with the cloud buzzword-filled database services.

    Last I read, Hacker News was still running on one big machine. And still uses text files as its database.

      Twitter runs ads and generates billions in revenue. It can't just tolerate being down or having under-load issues like HN often is.

"100 million certs a year" is only like ~3 certs a second. Maybe twice in peak. That's not much. And you're doing same error, focusing on one core feature and ignoring everything around it
