That's still correct.

What host do you use?

Hetzner.

I'd love to learn how you managed to scale on a single server - other than the above, any tips or tricks? I'm also a PHP guy on Ngnix with MySQL but want to know what tips you might have for a dynamic (non-static) site to handle such scale on a single server

Equip your server with a decent CPU, enough RAM to allow MySQL to keep most of your database in it, and fast SSDs. Profile your code and optimize/cache anything that stands out as slow, aggressively cache data that is read often using memcached/redis/etc, use an http cache proxy like cloudflare in front to cache static assets (and maybe pages that aren't dynamic for every user)

me also , how can it be 1 server ? how do you protect DDos attacks?

They use cloudflare in front, they do the heavy lifting.

Thanks!

When's the Next.js migration?
