Overview Of Azure Functions

Azure Functions is the serverless computing service hosted on the Microsoft Azure public cloud. It is serverless computing designed to accelerate and simplify application development.

It enables the user to run the service without managing the infrastructure and operate at scale in the cloud and integrate services using triggers and bindings.

It supports triggers, which are ways to start execution of your code, and bindings, which are ways to simplify coding for input and output data.

Azure Functions triggers

Functions provides templates to get you started with key scenarios, including the following:

  • HTTPTrigger
  • TimerTrigger
  • CosmosDBTrigger
  • BlobTrigger
  • QueueTrigger
  • EventGridTrigger
  • EventHubTrigger
  • ServiceBusQueueTrigger
  • ServiceBusTopicTrigger

Create an Azure Function

Enough talk! Here we will walk you through the Azure Function with HTTPTrigger. This way code will be executed by using HTTP Trigger.

In the below steps, we’re going to be showing you easy steps to create your first Azure Function.

1. Sign in to Azure Portal

2. Click Create a resource button found on the upper left-hand corner of the Azure portal, then select Compute > Function App.

4. Click on Create to provision and deploy the function app.

5. Select the Notification icon in the upper-right corner of the portal and watch for the Deployment succeeded message.
