  14. 14. FaaS Serverless can also mean applications where server- side logic is still written by the application developer, but, unlike traditional architectures, it’s run in stateless compute containers that are event-triggered, ephemeral (may only last for one invocation), and fully managed by a third party. One way to think of this is “Functions as a Service” or "FaaS". https://martinfowler.com/articles/serverless.html
