Learn basics of Azure Functions to get started

Azure Functions is a serverless solution that allows you to write less code, maintain less infrastructure, and save on costs. Instead of worrying about deploying and maintaining servers, the cloud infrastructure provides all the up-to-date resources needed to keep your applications running.

You focus on the code that matters most to you, in the most productive language for you, and Azure Functions handles the rest.

For the best experience with the Functions documentation, choose your preferred development language from the list of native Functions languages at the top of the article.

Development lifecycle

With Functions, you write your function code in your preferred language using your favorite development tools and then deploy your code to the Azure cloud. Functions provides native support for developing in C#, Java, JavaScript, PowerShell, Python, plus the ability to use more languages, such as Rust and Go.

Functions integrates directly with Visual Studio, Visual Studio Code, Maven, and other popular development tools to enable seamless debugging and deployments.

Functions also integrates with Azure Monitor and Azure Application Insights to provide comprehensive runtime telemetry and analysis of your functions in the cloud.

Hosting options

Functions provides a variety hosting options for your business needs and application workload. Event-driven scaling hosting options range from fully serverless, where you only pay for execution time (Consumption plan), to always warm instances kept ready for fastest response times (Premium plan).

When you have excess App Service hosting resources, you can host your functions in an existing App Service plan. This kind of Dedicated hosting plan is also a good choice when you need predictable scaling behaviors and costs from your functions.

If you want complete control over your functions runtime environment and dependencies, you can even deploy your functions in containers that you can fully customize. Your custom containers can be hosted by Functions, deployed as part of a microservices architecture in Azure Container Apps, or even self-hosted in Kubernetes.
