In this section, we'll deploy our first function to the public cloud, and learn how to call it. We'll be going live with our Azure Function, starting to create our serverless architecture. And to ensure that it happens correctly, we'll need a function project and a valid Azure subscription. Let's begin by implementing the following steps:

1. Right-click on your project and select Publish.... Now select Azure Function App | Create New as shown in the following screenshot:
   

2. Enter a memorable name and create a resource group and a consumption app service plan to match the following:
   

3. Click on the Publish button to publish your function.
4. Open a browser, navigate to http://portal.azure.com, and find your function. You can use the search bar and search the name of your function. Click on your Function App, then click on the function name. Click the Get function URL in the upper-right corner paste the address of your function into Postman, and test it. Please bear in mind that if you have a paid subscription, these executions will cost a small amount of money—you are only charged for the compute resources that you actually use. On a free account, you get a million executions for free.

Outcome

You now have a fully deployed and working Azure Function in the cloud.
