Summary

Completed

In Azure, a function only runs when something explicitly tells it to execute. In this module, we explored the timer, HTTP, and Blob storage triggers.

These three triggers are common triggers you can use to define your functions. Azure Functions provides a wide selection of both triggers and bindings that you can use to respond to connect your function code to Azure services and other partner services. Although each trigger type has specific requirements, the implementation and usage patterns are similar.

Clean up

The sandbox automatically cleans up your resources when you're finished with this module.

When you're working in your own subscription, it's a good idea at the end of a project to identify whether you still need the resources you created. Resources that you leave running can cost you money. You can delete resources individually or delete the resource group to delete the entire set of resources.

Check your knowledge

1.

A CRON expression is a string that consists of six fields that represent a set of times. The order of the six fields in Azure is: {second} {minute} {hour} {day} {month} {day of the week}. Suppose you needed a CRON expression that meant "every day", what special character would you put in the {day of the week} position?
