I once saw a website that took a full minute to load, and it was literally a page with images, text overflowing around it, and then some download links. But the way it was built... my god, the way it was built.
That company brought in a new "CTO", and his solution was to dump the entire thing in google cloud. I shit you not, this CTO initially installed an EOL version of PHP, and when errors started happening, he started submitting PR's to revert the PHP code to be compatible with the EOL version of PHP.
Dumpster Fire.
