With a timer trigger, we were able to speed up and slow down the calls towards that service.

In a recent project, we had some dependencies with external services that could throttle our calls to them. Because the trigger is not reactive on an external event, you control the speed in which tasks are executed. The biggest advantage is controlling speed. LetвЂ™s try understanding the Timer Trigger. This seems simple but the Timer trigger behaves a little bit differently when executed. Functions are just triggered by a вЂ¦ timer. If you choose for a consumption plan this can even result in a scale-out on the number of servers (which you do not have configured).ДЄzure Functions also offers a TimerTrigger. The more triggers are fired on the Azure Function, the more functions are executed. Then a Rest call on that endpoint triggers the function (HttpTrigger).ДЄll these triggers are scalable. For example, adding a blob in Azure Blob Storage (a BlobTrigger) or receiving a message in an Azure Event Hub can trigger the function (a EventHubTrigger).ДЄ function can also expose an external HTTP endpoint. Most of them are related to some event in another Azure resource. Multiple kinds of triggers are available. C#, Javascript, Java to write your function in. Multiple programming languages are supported e.g. You just deploy functions and do not care about the infrastructure underneath it. In essence, Azure Functions are just source-code functions, running on PaaS servers, which are triggered by some external mechanism. Azure Functions are MicrosoftвЂ™s way of offering serverless compute.
