This document provides an overview of serverless computing using Azure Functions. It discusses the benefits of serverless such as increased server utilization, instant scaling, and reduced time to market. Serverless allows developers to focus on business logic rather than managing servers. Azure Functions is introduced as a way to develop serverless applications using triggers and bindings in languages like C#, Node.js, Python and more. Common serverless patterns are also presented.

- 5. Before cloud How often should I patch my servers? How can I increase server utilization? How I deploy new code to my server? Which packages should be on my server? It takes how long to provision a new server?
- 6. Then came IaaS … How often should I patch my servers? How can I increase server utilization? How I deploy new code to my server? Which packages should be on my server? It takes how long to provision a new server?
- 7. Is it PaaS time? How often should I patch my servers? How can I increase server utilization? How I deploy new code to my server? Which packages should be on my server?

- 16. Azure Functions Process events with Serverless code. Make composing Cloud Apps insanely easy Develop Functions in C#, Node.js, F#, Python, PHP, Batch and more Easily schedule event-driven tasks across services Expose Functions as HTTP API endpoints Scale Functions based on customer demand Easily integrate with Logic Apps
- 18. Functions Programming Model Trigger (data) Input Input code Output Output • Function as a single unit of work • Functions are executed per trigger • Functions have inputs and outputs Input
- 20. Functions Programming Model - Best Practices • Functions should “do one thing” • Functions should be stateless • Functions should be idempotent • Functions should finish as quickly as possible 1
