Serverless

Also called: serverless computing, serverless function, serverless functions, cloud function, cloud functions, edge function, scale to zero, scale-to-zero

A way to run code where the cloud provider sets up and looks after the servers. Servers still exist, but the customer does not manage them. Capacity adjusts on its own, and the bill covers only the time the code runs.

For example: A site's contact form runs as a serverless function. On a day with no messages it costs nothing. On a busy day the provider runs many copies at once.
