Serverless just means not hosting your own infrastructure + boxes. Amazon Lambda is a good example where you run arbitrary script on their infrastructure on demand, without having always-available servers.
I find the term "serverless" quite misleading. Essentially, all the code in the world has to run on a machine so there is nothing really "server-less" about it.
It's probably more accurate to say something like "devops-free" since management of servers is hived off to a third party. Sounds less buzz-worthy, so maybe someone can come up with something better.
But there is still a database? (I realize this wasn't mentioned in the thread title). yeah "serverless" seems kind of mis-leading. I'm wondering though what "script/language" you'd write this. How to store... should probably learn how to read first.
