In this lab we will practice In this lab we will practice creating a web app in the Azure


Azure is cloud offering by Microsoft.

Azure offers a large collection of services including

Azure, like other cloud platforms, relies on virtualization.

Most computer hardware can be emulated in software, because most computer hardware is simply a set of instructions encoded in silicon.

Using a virtualization layer that maps software instructions to hardware instructions, virtualized hardware can execute in software as if it were the actual hardware itself.

The cloud is a set of physical servers in datacenter that execute virtualized hardware on behalf of customers.

You have two option to complete this lab

  1. Use your own azure subscription, you can sign up for trial here

  2. Use Microsoft Learn sandbox. Check more details here

Select Create a resource from the Azure portal’s Azure services section. The pane to create a resource appears.

}} Select Web App.

If you don’t see it, in the search box, search for and select Web App.

select web app}} The Create Web App resource pane appears.

web app pane}}

On the Basics tab, enter the following values for each setting.

Project Details


Concierge Subscription

The web app you are creating must belong to a resource group. Here, you select the Azure subscription to which the resource group belongs (or will belong, if you are creating it within the wizard).

Resource Group

From the dropdown list, select [Learn-XXXXX] The resource group to which the web app will belong. All Azure resources must belong to a resource group.

Instance Details

Name Enter a unique name The name of your web app.

This name will be part of the app’s URL:

The name you choose must be unique among all Azure web apps.

Publish Code

The method you want to use to publish your application.

When publishing an application as code, you also must configure Runtime stack to prepare App Service resources to run your app.

Runtime stack Python 3.8

The platform on which your application will run.

Your choice may affect whether you have a choice of operating system - for some runtime stacks, App Service supports only one operating system.

Operating System

Linux The operating system used on the virtual servers that will run your app.

Region Select West US or Central US

The geographical region from which your app will be hosted.

App Service Plan

Linux Plan Accept default

The name of the App Service plan that will power your app.

By default, the wizard will create a new plan in the same region as the web app.

Sku and size F1

The pricing tier of the service plan being created.

This determines the performance characteristics of the virtual servers that power your app, and the features it has access to.

Select Review + Create to go to the review pane

web app basic settings}} and then select Create.

The portal will show the deployment pane, where you can view the status of your deployment.

web app deployment status}} When deployment is complete, select Go to resource. The portal shows the App Service Overview pane for your web app.

To preview your web app’s default content, select the URL at the top right.

The placeholder page that loads indicates that your web app is up and running, and is ready to receive deployment of your app’s code.

web app preview}} Leave the browser tab with the new app’s placeholder page open. You’ll come back to it after you’ve deployed your app.

This step should be done on you local linux machine, we are using cloud shell for this lab.

Click here to activate cloud shell

Click on Cloud Shell link in top right of as shown below

}} Cloud shell terminal will appear in bottom of webpage.


Enter below command to check Python version is 3.6 or higher

az login

You will get below output

Cloud Shell is automatically authenticated under the initial account signed-in with. Run 'az login' only if you need to use a different account
To sign in, use a web browser to open the page and enter the code XXXXXX to authenticate.

Click on url in output and enter code in below window

azure login}} Click continue on below window

web app confirmation}} You will get below window after everything goes well.

web app preview}} You may close this window and come back to azure portal.

In cloud shell you see message similar to below.

    "cloudName": "AzureCloud",
    "homeTenantId": "XXXXXXXX",
    "id": "XXXXXXX",
    "isDefault": true,
    "managedByTenants": [],
    "name": "Concierge Subscription",
    "state": "Enabled",
    "tenantId": "604c1504-c6a3-4080-81aa-b33091104187",
    "user": {
      "name": "[email protected]",
      "type": "user"

Clone the sample repository using the following command and navigate into the sample folder.

git clone

cd python-docs-hello-world

python3 -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt

az webapp up --sku B1 --name azure103

You will get messages on creating and deploying webapp

Refresh the browser window where you have site open or open URL Again

You will see below

web app preview with sample}}


press i for insert and modify it to look like below

from flask import Flask
app = Flask(__name__)

def hello():
    return "Hello, World from azure lab 103"

Press escape on keyboard and “:wq” to save and exit from vi

Run below command to redeploy

az webapp up --sku B1 --name azure103

You will get messages on creating and deploying webapp like before

Refresh the browser window where you have site open or open URL Again

You will see that changes we made have been updated

web app preview}}


You’ve successfully created and deployed a web application to Azure App Service.

App Service simplifies managing and controlling your web app in comparison to traditional hosting options.

Your App Service Plan can help you reduce the time and effort spent running and managing your web app, and provide advanced cloud features such as autoscaling and Git integration.

Clean up

The sandbox automatically cleans up your resources when you’re finished with this module.

When you’re working in your own subscription, it’s a good idea at the end of a project to identify whether you still need the resources you created. Resources left running can cost you money.

You can delete resources individually or delete the resource group to delete the entire set of resources.
