A few weeks ago Matthieu Napoli released Bref, a tool to get any PHP project up and running in a serverless environment. Matthieu has managed to get working serverless too.

Serverless basically means “Running apps without worrying about servers”. The main difference with a traditional hosting is that you do not maintain the servers and reserve their capacity. They are scaled up or down automatically and you pay only for what you use. ... Today let’s try to deploy a Laravel application on AWS lambda using Bref.
