Azure Function Using Portal

Introduction to Azure Function

•Azure Functions is one implementation of Server-less Architecture also known as 

Functions as a Service (FaaS).

•In Azure Functions there are no virtual machines (VMs) to manage.

•In Azure function A number of discrete functions live inside a Function app.

•It run either in a consumption plan or App Service plan.

Create Function App

Go to Create a Resources->Search for Function App->Create

Figure-1

Create Function App

Figure-2

Create Function App

Function App will be created with the name MyNewAzureFunApp as shown above.
Lets create a function Under the function app.

Select the function app called MyNewAzureFunApp  and then select In-Portal as shown in Figure-3.

Figure-3

Create Function

Select Timer or Select More template and select timer trigger and give a name to the timer and time interval when the timer will trigger.  as shown in Figure -4

Figure -4

Create Function

Function(TimerTrigger1) will be created under the function app.

Function and the files

Find the newly created function and file in below figure-5 and figure-6.
