Serverless is a big topic these days. More specifically, Function as a Service (FaaS) enables small-scale functions deployed in the cloud to be enabled only as needed. Compared to Platform as a Service (PaaS) services which are “always on” and require explicit scaling, FaaS services wake up when needed and are scaled by the platform automatically.

Imagine a service that only gets invoked one per hour. In PaaS, that service is always running and ready to handle requests, consuming processor resources and ultimately costing more to be ready at a moment's notice. In contrast, FaaS services awaken quickly upon invocation and go away when finished, conserving resources and cost.

In this example-driven session, we'll see how to create and deploy Function as a Service (FaaS) services with Spring and Spring Boot.
