  • Build a Web API
  • Process file uploads
  • Responding to database changes
  • Running scheduled tasks
  • Analyze IOT data streams
  • Process data in Realtime
• As we build Azure fuctions, we have the following options

Creating an Azure Function

• Refer Here for the official article
• Install Azure Functions Core Tools Refer Here
• Ensure Azure Functions Extension is added to Visual Studio Code
  
• Create a local project Refer Here
• Refer the classroom video for the sample Azure function created and tested

import logging

import azure.functions as func


def main(req: func.HttpRequest) -> func.HttpResponse:
    logging.info('Python HTTP trigger function processed a request.')

    isValid = True
    try:
        req_body = req.get_json()
        p = req_body['principal']
        t = req_body['time']
        r = req_body['rate']
        si = p * t * r /100
    except ValueError:
        isValid = False


    if isValid:
        return func.HttpResponse(f"Simple Intrest is {si}")
    else:
        return func.HttpResponse(
             "Ensure you send a json body with principal time and rate",
             status_code=200
        )
