Serverless in Context
Getting the Most From Azure Functions
The course is part of these learning paths
An Introduction to Azure Functions
Serverless Computing has emerged as a capable and low-friction means to execute custom logic in the public cloud. Whether you're using Amazon Lambda, Google Cloud Functions, or Azure Functions, you have a wide variety of target languages, ecosystem integrations, and deployment mechanisms to choose from. All this while leaving the heavy lifting of server provisioning and maintenance to the experts, which gives you plenty of time to focus on your differentiated application functionality.
In this "Introduction to Azure Functions" course, you’ll learn how to build Azure Function applications in the cloud. You'll discover the core feature set of Functions and see how to integrate with a variety of sibling Azure services. You'll explore Function topics like security, monitoring, deployment, and testing best practices. You'll also learn about ideal Functions use cases and the pricing model. Finally, you'll learn about how we've arrived at the serverless computing model, and where serverless is likely to go in the future. By the end of this course, you’ll have a solid foundation to continue exploring Functions on your own, and incorporating Azure Functions capability into your work.

Let's briefly summarize what you've learned.
First you learned about Serverless in the context of what's come before it and about common features of all Serverless platforms.
Next, you reviewed the feature set of Azure functions, its Azure App Service foundation, support for multiple target platforms, like .NET and Node.js, HTTP proxies, and OAuth Security.
You explored Triggers and Bindings to learn various ways to invoke as your functions and declaratively pass bound data in to and out of function bodies.
You looked at Testing and Debugging support. As well as, options for integrating with the CI/CD deployment pipeline and monitoring your function apps in production.
You learned about common use cases for functions and compared the two pricing models available.
Finally, you learned that Serverless compute is really part of a larger trend towards abstracting infrastructure of all kinds behind a managed facade, allowing you to focus more on adding business value and less on the undifferentiated heavy lifting of infrastructure management.
