You can sign up for Azure Free Trial subscription here: https://azure.microsoft.com/en-us/free/
It provides you with $200 Azure credit.
You’ll have 30 days to use it—in addition to free services.
Make sure that you continue monitoring your usage and billing at Azure portal. If you exceed your usage of resources which are not included as free services as part of the Free trial subscription, you could be charged for those on your credit card.
The spending limit in Azure prevents spending over your credit amount. All new customers who sign up for an Azure free account or subscription types that include credits over multiple months have the spending limit turned on by default. The spending limit is equal to the amount of credit. You can't change the amount of the spending limit. For example, if you signed up for Azure free account, your spending limit is $200 and you can't change it to $500. However, you can remove the spending limit. So, you either have no limit, or you have a limit equal to the amount of credit. The limit prevents you from most kinds of spending. When your usage results in charges that exhaust your spending limit, the services that you deployed are disabled for the rest of that billing period.
