What Is Web Server in Azure?


Angela Bailey

A web server is a software application that handles HTTP requests sent by clients, such as web browsers, and delivers the requested resources over the internet. In the context of Azure, a web server refers to the service provided by Microsoft Azure for hosting websites and web applications. Azure offers various types of web servers, including virtual machines (VMs) running popular server software like Apache or Internet Information Services (IIS), as well as platform-as-a-service (PaaS) offerings like Azure App Service.

Virtual Machines as Web Servers in Azure

Azure Virtual Machines allow you to deploy and manage your own custom web servers. This means you have full control over the server software and configuration.

You can choose from a wide range of VM sizes, operating systems, and pre-configured images available in the Azure Marketplace. For example, you can create a VM running Windows Server with IIS or Ubuntu with Apache.

To set up a virtual machine as a web server in Azure:

  1. Create a new virtual machine or use an existing one.
  2. Install the desired web server software on the VM.
  3. Configure firewall rules to allow incoming HTTP/HTTPS traffic.
  4. Optionally, secure your website with SSL/TLS certificates.

Azure also provides features like load balancing and auto-scaling to ensure high availability and performance for your virtual machine-based web servers.

Azure App Service as a Platform for Web Servers

Azure App Service is a fully-managed platform-as-a-service offering that abstracts away the underlying infrastructure management. With App Service, you can focus on deploying your web applications without worrying about server provisioning, scaling, or maintenance tasks.

Key features of Azure App Service include:

  • Support for multiple programming languages and frameworks, such as .NET, Node.js, Java, and Python.
  • Easy deployment from source control repositories (e.g., GitHub, Azure DevOps).
  • Built-in scaling options to handle increased traffic.
  • Integration with Azure services like Azure SQL Database and Azure Storage.

To create a web server using Azure App Service:

  1. Create an App Service plan, which defines the computing resources for your app.
  2. Create a web app within the App Service plan.
  3. Deploy your web application code or configure deployment from a repository.

Azure App Service offers advanced features like deployment slots for staging environments and automatic backups to ensure seamless deployments and disaster recovery capabilities for your web applications.


In summary, a web server in Azure refers to the hosting service provided by Microsoft Azure for websites and web applications. Whether you choose to use virtual machines or Azure App Service, Azure offers flexible options for hosting your web servers based on your requirements.

Virtual machines provide full control over the server software and configuration, while App Service abstracts away infrastructure management tasks to simplify deployment and scaling of web applications. With Azure’s powerful features and scalability options, you can ensure reliable performance and availability for your web servers in the cloud.
