Palms-on Lab – Create a sturdy perform in C#
Steps to be adopted,
Open VS 2019 and create a undertaking.
Select the Azure perform template and create a listing.
Select sturdy capabilities orchestration template.
As soon as the appliance has been created, we are able to see three capabilities,
- Function1 – Foremost performance perform which internally calls Function1_Hello a number of occasions and returns the consequence.
- Function1_Hello – Intermediate perform will get referred to as from Function1 a number of occasions, liable for manipulating the enter and generate output.
- Function1_HttpStart – Operate within the type of HTTP set off which is liable for initiating Function1 and collect the response.
Run (F5) the appliance and see all of the capabilities which have been listed right here.
Copy the URL of Function1_HttpStart and run it within the browser.
Copy the URL of statusQueryGetUri (GET URLK) and run it within the browser.
Right here, you’ll be able to see the response from Function1 which received instantiated from Function1_HttpStart with the specified output.
Palms-on Lab – Deploy sturdy perform on Azure
Steps to be adopted,
Proper-click on the perform and click on on publish and select goal as Azure.
Select an choice as Azure perform app (Home windows).
Create/select the brand new/present useful resource group and useful resource for azure perform deployment.
Click on on End and let it get revealed and as soon as revealed, go to the Azure portal and take a look at the perform app utilizing the steps which we did above whereas creating sturdy capabilities.
It is a fundamental instance of orchestration calling the identical perform a number of occasions.
There are a number of patterns that signify the use-cases of sturdy capabilities, keep tuned for the following sequence of articles to get the dangle of it.
Completely satisfied studying!
