Serverless was always around and always had a place. It used to be a shell and sftp account on a shared Linux server where you could upload your html and cgi scripts or php files into your own Apache virtual host and get billed per hit on your web site or bandwidth usage. It now just has a lot of tooling around it with a big learning curve and vendor lock in, but at least you get your hits and bandwidth for cheaper than you used to.
