WebJobs enables applications to run background tasks in the same instance as a web app. The Workflow Studio has four new types of templates based on triggers for the Azure WebJobs. The triggers determine which event invokes the WebJob. Please consider the different available triggers below to choose the appropriate template.

• Queue Trigger – The Queue trigger starts the WebJob when a new message is received on a queue.

• Timer Trigger – This trigger will start the WebJob based on the timer (Timestamp/CRON) value.

• Blob Trigger – Blob Trigger will invoke the WebJob when a file is uploaded to the blob container.

• Continuous – This web job will be manually invoked while starting the application and runs continuously.
