help Azure Functions FAQ

Which languages can Azure Functions run?

Azure Functions supports several common stacks, including C#, JavaScript, TypeScript, Python, Java, and PowerShell. That makes it practical for both Microsoft-heavy .NET teams and scripting-heavy automation teams.

How do Azure Functions connect to Event Hubs or Service Bus?

Azure Functions uses triggers and bindings so a function can run from services like Azure Event Hubs, Azure Service Bus, or HTTP requests. This is one reason it fits event-driven workflows inside the Azure ecosystem.

What is the difference between Consumption and Premium plans in Azure Functions?

The Consumption plan scales automatically and bills based on execution, while the Premium plan keeps instances warm and supports features like VNET integration. Teams often move to Premium when cold starts or networking requirements become important.

Can Azure Functions replace an App Service API?

It can replace parts of an API when the endpoints are event-driven, small, or bursty. For a long-running web application with persistent middleware and predictable traffic, Azure App Service or Azure Container Apps may be simpler.
