Assuming that you don't have a subscription at the moment: 

You have multiple options here : 

- Pay As you go (With Credit card)

- CSP (with MS Partner https://partner.microsoft.com/en-us/partnership/new-commerce )

- EA (Direct with MS based on your usage commitment) 

You can quickly start consuming Azure with the below steps  creating PAYG subscription : 

1. Go to the Azure website (https://azure.microsoft.com/) and click on the "Start free" button.

2. Follow the prompts to create an account by providing your email address, creating a password, and verifying your identity.

3. Once you have created your account, navigate to the Azure portal (https://portal.azure.com/).

4. Click on the "Create a resource" button (the plus sign in the left-hand menu) and search for "Function App".

5. Select "Function App" from the search results, and click on the "Create" button.

6. Fill out the form with the necessary information, such as the name of your Function App, the subscription you want to use, the resource group you want to create it in, and the hosting plan.

7. Choose your preferred runtime stack for your Function App (e.g., .NET, Node.js, Python, etc.).

8. Click on the "Create" button to create your Function App.

9. Once your Function App is created, you can create and publish your first function by selecting your Function App from the Azure portal dashboard and clicking on the "Functions" menu.

10. From there, you can create a new function by selecting a template, language, and trigger type, and then write your code.

11. Once you have written and tested your function, you can publish it to your Function App by clicking on the "Publish" button in the Azure portal.
