Session 6: Serverless, Containers, and FaaS

example cloud architecture example real-world cloud application

What is "Serverless?"

There are many definitions that include more or less categories of cloud services. The primary concept is you create an 'exectution environment' to run your code, but you don't manage any aspect of the server. You can focus on your application or code and not the operating system.

We will talk about two kinds of "serverless" computing:

  • Cloud Functions: running code on demand in response to a trigger or event. This is sometimes called "Function as a Service"
  • Linux Containers: sandbox environment for running software, even more abstract than Virtual Machines, s

The relationship is the Cloud functions use Linux Containers as the basis for their architecture on Azure. However you can use Azure Functions without working with containers or even knowing that fact but if you need extreme customization.

FaaS is a blackbox

Serverless Readings

As you read these materials, do you think "serverless" resources are IaaS or PaaS? They sure feel like infrastructure as they require significant configuration, but run like PaaS, hence they are often called "Function as a Service."

Containers

Containers are a widespread technology not just for Azure.
