4. Serverless & Azure Functions Overview
5. Serverless
      
6. Serverless
   https://martinfowler.com/articles/serverless.html   BaaS ( Backend as a Service) FaaS ( Functions as a Service) 
7. 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
