Azure Web Apps is a cloud platform that enables you to host your web applications in a scalable and reliable environment. As part of Microsoft Azure’s App Service, Web Apps offer features such as easy deployment, custom domains, and the ability to integrate with databases and other Azure services. This guide aims to walk you through the process of getting started with Azure Web Apps, providing you with a comprehensive path from setup to deployment for beginners.

What are Azure Web Apps?

Azure Web Apps is one of the components of Azure App Service, which facilitates the creating and hosting of web applications in various programming languages such as .NET, PHP, Node.js, and Python. It provides a platform-as-a-service (PaaS) environment, which means you can focus on building your application without worrying too much about the underlying infrastructure.

Key Features of Azure Web Apps

• Automatic Scaling: Azure Web Apps can automatically scale your app according to demand.
• Integrated Development Tools: Integration with Visual Studio and GitHub allows for seamless development and deployment.
• Custom Domains: Host your web application with a custom domain name.
• Security: Built-in security features to protect your data and applications.
• Continuous Deployment: Supports CI/CD pipelines through integrations with DevOps tools.

Creating an Azure Account

To start using Azure Web Apps, you will need an Azure account. If you don’t have one yet, follow these steps to create your account:

1. Visit the Azure Free Account Page.
2. Click on the “Start free” button.
3. Sign up using your Microsoft account or create one if you don’t have it yet.
4. Fill in the required information and complete the verification process.

Once your account is created, you’ll get access to various Azure services and a free credit to use during your first month.

Setting Up Your First Azure Web App

Step 1: Access the Azure Portal

Log in to your Azure account by visiting the Azure Portal. Here, you’ll find a customizable dashboard to manage all your Azure services.

Step 2: Create a New Web App

1. On the left sidebar, click on “Create a resource.”
2. In the search box, type “Web App” and select it from the dropdown list.
3. Click on the “Create” button to initiate the web app creation process.

Step 3: Configure Your Web App

In the “Create Web App” section, you will need to fill out several configuration settings:

• Subscription: Choose the Azure subscription you’d like to use.
• Resource Group: Either create a new resource group or select an existing one to organize your Azure resources.
• Web App Name: Enter a unique name for your web app; this will also be part of your app’s URL.
• Publish: Choose “Code” or “Docker Container,” depending on how you plan to deploy your application.
• Runtime Stack: Select the technology stack your application will use (e.g., .NET, Node.js, PHP).
• Region: Choose the geographic location for your web app for optimal performance regarding your user base.

Step 4: Review and Create

Once you’ve filled in all necessary fields, click the “Review + Create” button. A validation process will take place, and once completed, you can click “Create” to provision your new web app. This may take a few moments.

Deploying Your Web App

Deployment in Azure Web Apps can be accomplished through several methods. Here are the most common ways to deploy your application:

Method 1: Using Azure DevOps

Azure DevOps allows you to set up CI/CD pipelines for deploying your applications automatically. Here’s how to do it:

1. Create a new project in Azure DevOps.
2. Push your code to the Azure Repos repository.
3. Set up a build pipeline to define how your application is built and packaged.
4. Configure a release pipeline that deploys the built application to your Azure Web App instance.

Method 2: Using GitHub Actions

If you prefer GitHub for version control, you can utilize GitHub Actions for deployment:

1. Make sure your application code is pushed to a GitHub repository.
2. Create a new workflow in the .github/workflows directory.
3. Use the azure/webapps-deploy action to deploy your code to Azure Web Apps.

Below is a sample GitHub Actions YAML file:

name: Build and Deploy to Azure Web App
on:

  push:

    branches:

      - main
jobs:

  build-and-deploy:

    runs-on: ubuntu-latest
steps:

    - name: Checkout code

      uses: actions/checkout@v2
- name: Set up Node.js

      uses: actions/setup-node@v2

      with:

        node-version: '14'
- name: Install dependencies

      run: npm install
- name: Build app

      run: npm run build
- name: Deploy to Azure Web App

      uses: azure/webapps-deploy@v2

      with:

        app-name: 'YOUR_APP_NAME'

        publish-profile: ${{ secrets.AZURE_PUBLISH_PROFILE }}

        package: '.'

Method 3: FTP Deployment

You can also deploy your application using FTP:

1. Open the Azure Portal and navigate to your web app.
2. Under the “Deployment Center,” select “FTP” as your deployment method.
3. Copy the FTP endpoint and credentials provided.
4. Use an FTP client (like FileZilla) to upload your application files to the server.

Configuring Your Web App

Once your web app is deployed, you might want to configure various settings to optimize its performance and security:

Application Settings

In the Azure Portal, navigate to your web app and select “Configuration.” Here, you can add application settings that are essential for your app to run, such as connection strings and environment variables.

Scaling Your App

You can scale your Azure Web App either vertically or horizontally:

• Vertical Scaling: Increase the price tier of your app service to add more resources (CPU, RAM).
• Horizontal Scaling: Increase the number of instances running your app to handle more load.

Custom Domains and SSL

To add a custom domain to your web app, go to the “Custom domains” section and follow the instructions to verify ownership of the domain. Additionally, you can configure SSL for secure connections using Azure’s App Service Managed Certificates.

Monitoring and Troubleshooting

Azure provides several monitoring tools to keep track of your application’s performance and troubleshoot issues:

AWS Metrics

Under the “Metrics” tab in your web app’s overview, you can view important metrics like CPU usage, HTTP request counts, and more.

Application Insights

By enabling Application Insights, you can gain deeper insights into application performance, usage patterns, and application exceptions:

1. In the Azure Portal, select “Application Insights” from your web app.
2. Follow the prompts to enable it and install the required SDK in your application.

Log Stream

The Log Stream feature allows you to view logs and errors in real-time, which is beneficial for immediate troubleshooting:

1. Navigating to the “Log Stream” in your Azure Web App.
2. Start streaming logs to observe real-time output.

Pricing Models

Azure Web Apps operate on a pay-as-you-go pricing model. Pricing is determined based on the selected App Service plan, which varies in terms of features, performance, and scalability:

• Free Tier: Basic features for development and testing; limited resources.
• Shared Tier: Hosts several apps on the same server for a minimal cost.
• Basic and Standard Tiers: Ideal for medium to large applications with dedicated resources and scaling options.
• Premium Tier: Best for enterprises requiring advanced features and high performance.

Best Practices for Azure Web Apps

• Use Application Insights: Always enable Application Insights to monitor performance and errors.
• Implement CI/CD: Set up a continuous deployment pipeline to streamline updates.
• Back Up Your App: Regularly back up your web apps and databases to prevent loss of data.
• Optimize Performance: Regularly review scaling settings and performance metrics to optimize resource usage.
• Security Features: Implement security best practices, including configuring firewalls, enforcing SSL, and using Managed Identity.
