Architecture introduction
Johan Louwers

FN Project
Serverless
What is Serverless?
Serverless is an abstraction of infrastructure and its operations including
provisioning, scaling, patching, etc.
Serverless architecture is when an app is built entirely on serverless
components (compute, storage, networking)
