This document contains information from a presentation on Azure Functions including: - An overview of Azure Functions and their pay-per-use model with instant scalability. - Details on the anatomy of a function including triggers, bindings, and their associated classes. - Explanations of the startup and runtime phases of functions and how triggers and bindings are configured. - Recommendations to write efficient functions that avoid unnecessary resource usage. - Links provided for additional documentation, code samples, and the speaker's contact information.
Empower every Azure Function to achieve more!!
- 1. This session will commence shortly We are constantly striving to create excellent content and would appreciate if you could take this brief survey. Survey Link: https://aka.ms/Reactor/Survey Please enter the event code 12788 at the start of survey
- 2. meetup.com/Microsoft-Reactor-Stockholm/ Speaker Slide: Massimo Bonanni Azure Technical Trainer @ Microsoft I spend my time to help customers to empower their Azure skills to achieve more and leverage the power of Azure in their solutions. I’m also a technical speaker both for local and international events and a user-group guy. I founded Aa couple of communities in Italy and collaborated with most of the Italian communities. Finally, I is also passionate about biking, reading, and dogs!!

- 4. Be aware of others Be friendly and patient Be welcoming and respectful Be open to all questions and viewpoints Be understanding of differences Be kind and considerate to others
- 5. meetup.com/Microsoft-Reactor-Stockholm/ Pay-per-use Only pay for what you use: billing is typically calculated on the number of function calls, code execution time, and memory used.* Instant, event-driven scalability Application components react to events and triggers in near real-time with virtually unlimited scalability; compute resources are used as needed. What is serverless? Full abstraction of servers Developers can just focus on their code—there are no distractions around server management, capacity planning, or availability.
- 6. meetup.com/Microsoft-Reactor-Stockholm/ What are Azure Functions? Author functions in C#, F#, Node.JS, Java, and more Code Events React to timers, HTTP, or events from your favorite Azure services, with more on the way Outputs Send results to an ever-growing collection of services

- 9. meetup.com/Microsoft-Reactor-Stockholm/ Extend triggers and bindings All Triggers and Bindings (except for HTTPTrigger and Timer Trigger) are available as external packages. The Azure Functions SDK is based on the Azure WebJobs SDK and inherits the extension SDK from it. An extension is a class that implements the IExtensionConfigProvider interface.
- 10. meetup.com/Microsoft-Reactor-Stockholm/ Azure Functions lifecycle phases Startup The runtime executes this phase only when the host starts. The runtime registers the built-in binding (TimerTrigger and HttpTrigger). You must register your custom extensions. Runtime The runtime executes this phase every time a function is triggered by an event.

- 20. meetup.com/Microsoft-Reactor-Stockholm/ Startup Phase The runtime creates the factory for binding The runtime uses the factory to create the binding instance The runtime uses binding class to create the listener The runtime starts the listener

- 28. meetup.com/Microsoft-Reactor-Stockholm/ Startup Phase Runtime Phase The runtime creates the extension The runtime creates the converter When the listener fires a function (FunctionExecutor), the runtime uses the converter to create the binding class
- 30. meetup.com/Microsoft-Reactor-Stockholm/ Takeaways Implementing your own triggers and bindings allows you to abstract the data source with respect to the Azure Function code. You pay for duration and memory occupation of your function. Your code must be efficiently and avoid to load assembly that you don’t use. Trigger listener is one of the most important classes for scalability and performance: write it once and the best you can!!!
