With your webhost, you have to setup and maintain the server, including patching/updating it, setting up SSL, etc.

I used to do that for side projects, but I've had too many servers, and maintaining them was a pain.

For something with high traffic, Lambda provides the instant scalability. Imagine servers autoscaling, but instantly. And again, without having to setup or maintain that.

You're confusing a root server or a VPS with a webhost aka "shared hosting", where the hosting service takes care of Let's Encrypt certificates, and scheduled downtime for patching.
