Unlocking the Cloud: A Step-by-Step Guide to Hosting Your Web App on Azure App Service

The digital landscape is ever-evolving, and businesses of all sizes are recognising the necessity of a robust online presence. Microsoft Azure’s App Service offers a powerful platform for hosting web applications, whether they are built using .NET, Node.js, Python, or PHP. If you’re ready to elevate your web application to the cloud, this step-by-step guide will help you navigate the process of hosting on Azure App Service.

Step 1: Create an Azure Account

Before diving into the technicalities, the first thing you’ll need is an Azure account. Fortunately, Microsoft offers a free tier that provides ample resources to get you started. Simply visit the Azure website and sign up. Once registered, you’ll gain access to the Azure Portal, your central hub for managing your services.

Tip:

Ensure you verify your email address and set up any necessary billing information, even if you are planning to use the free tier.

Step 2: Prepare Your Web Application

Prepare your web application to be deployed. This involves ensuring your app is free of critical errors and meets the necessary framework requirements. Make sure to test your app locally to confirm it behaves as expected.

Considerations:

• If your application uses a database, ensure that it’s correctly configured to use Azure SQL Database or another supported service.
• Organise your files and dependencies carefully to facilitate a smooth deployment.

Step 3: Create an Azure App Service

1. Log into the Azure Portal: Navigate to the Azure Portal using your account credentials.

2. Select ‘Create a resource’: Click on the “+ Create a resource” button located at the top left corner.

3. Find App Service: In the marketplace, search for “App Service” and click on it.

4. Fill in the App Service Details: You will need to provide basic information such as:

   • Subscription: Choose your active subscription.
   • Resource Group: Either select an existing resource group or create a new one.
   • Name: Assign a unique name to your App Service. This name will be part of the URL.
   • Publish: Choose “Code” if you’re deploying from a local machine or “Docker container” if you’re using a container.
   • Runtime stack: Select the programming language and version your application uses.
   • Region: Choose a location closer to your target audience to reduce latency.

5. App Service Plan: Here you can decide on the pricing tier. The free tier is quite capable for basic demonstrations and testing.

6. Click ‘Review + Create’: Review all your settings, and if everything looks good, proceed to hit ‘Create’.

Step 4: Deploy Your Web Application

Upon successful creation, it’s time to deploy your application:

1. Navigate to Your App Service: Click on ‘App Services’ in the left sidebar, then select your newly created app.

2. Deployment Centre: In the settings menu of the app, find and select ‘Deployment Centre’. This section allows you to choose your deployment method. Common options include:

   • Local Git: If you want to manually push updates from your local repository.
   • GitHub Integration: For continuous deployment directly from your GitHub repository. You’ll need to authenticate and select the appropriate repository and branch.
   • Azure DevOps: Alternatively, you can set up a pipeline through Azure DevOps for more complex CI/CD needs.

3. Configure Settings and Deploy: Depending on your chosen method, follow the prompts to link your repository or upload your app files. Click ‘Finish’ or ‘Deploy’ to initiate the upload.

Troubleshooting:

If you encounter any issues, check the Logs section within the App Service for detailed error messages.

Step 5: Configure Application Settings

Once deployed, you might need to set environmental variables or connection strings:

1. Go to ‘Configuration’: In the Settings section of your app, navigate to ‘Configuration’.

2. Add Application Settings: Here, you can add new settings that your application may require. For example, database connection strings or API keys.

3. Save Changes: Don’t forget to save your changes and restart the App Service if prompted.

Step 6: Test Your Application

Visit your web app by navigating to the URL provided in the Overview section of your App Service. Test every feature to ensure that everything is functioning as expected. This step is crucial to confirm that your app performs correctly in the cloud environment.

Step 7: Monitor and Scale Your Application

Azure offers various tools to monitor the performance and health of your application:

• App Insights: This feature provides detailed analytics about your app’s performance, including request rates and failure rates. You can enable it in the ‘Application Insights’ section of your App Service.

• Scaling: As your application grows, you may need to scale vertically (upgrading to a higher pricing tier) or horizontally (adding more instances). You can manage scaling in the ‘Scale up’ or ‘Scale out’ section.
