Creating a 3-Tier Application Using Azure Virtual Machines

Azure Virtual Machines is a powerful platform for building and deploying scalable applications in the cloud. In this article, we’ll walk through how to create a 3-tier application using Azure Virtual Machines.

What is a 3-Tier Application?

A three-tier application is a client-server architecture that includes three primary tiers – presentation, application, and database. The presentation tier is responsible for displaying the user interface. The application tier contains the logic that processes user requests and generates responses. The database tier is where the data is stored.

Creating a Three-Tier Application Using Azure Virtual Machines

To create a three-tier application using Azure Virtual Machines, we’ll need to set up three virtual machines – one for each tier. We’ll use the following Azure services:

Azure Resource Group – This will be used to organize the resources we’ll be creating for our three-tier application.

Azure Virtual Network – This will be used to set up a private network that will be used by our virtual machines.

Azure Virtual Machine – We’ll create three virtual machines – one for the presentation tier, one for the application tier, and one for the database tier.

Azure Storage Account – This will be used to store the virtual machine disks.

Let’s walk through the steps to create our three-tier application.

Step 1: Create an Azure Resource Group

The first step is to create an Azure resource group. An Azure resource group is a logical container that will hold all the resources we’ll need for our three-tier application.

To create an Azure resource group, follow these steps:

Log in to the Azure portal.
Click on the “Create a Resource” button in the top left corner.
Select “Resource Group” from the list of options.
Enter a name for your resource group.
Choose the location where you want to create your resource group.
Click on “Create”.

Step 2: Create an Azure Virtual Network

The next step is to create an Azure Virtual Network. This will be used to create a private network that will be used by our virtual machines.

To create an Azure Virtual Network, follow these steps:

Navigate to your newly created resource group.
Click on the “Create a resource” button.
Select “Virtual Network” from the list of options.
Enter a name for your virtual network.
Choose the location where you want to create your virtual network.
Set the address space and subnet that you want to use.
Click on “Create”.

Step 3: Create an Azure Virtual Machine for the Presentation Tier

The next step is to create an Azure Virtual Machine for the presentation tier. This virtual machine will host the user interface.

To create an Azure Virtual Machine, follow these steps:

Navigate to your newly created resource group.
Click on the “Create a resource” button.
Select “Windows Server” from the list of options.
Choose the location where you want to create your virtual machine.
Configure the virtual machine settings, such as the size, username, and password.
Select the virtual network that you created in step 2.
Click on “Create”.

Step 4: Create an Azure Virtual Machine for the Application Tier

The next step is to create an Azure Virtual Machine for the application tier. This virtual machine will host the logic that processes user requests and generates responses.

To create an Azure Virtual Machine, follow these steps:

Navigate to your newly created resource group.
Click on the “Create a resource” button.
Select “Windows Server” from the list of options.
Choose the location where you want to create your virtual machine.
Configure the virtual machine settings, such as the size, username, and password.
Select the virtual network that you created in step 2.
Click on “Create”.

Step 5: Create an Azure Virtual Machine for the Database Tier

The final step is to create an Azure Virtual Machine for the database tier. This virtual machine will host the data that is stored in our three-tier application.

To create an Azure Virtual Machine, follow these steps:

Navigate to your newly created resource group.
Click on the “Create a resource” button.
Select “SQL Server” from the list of options.
Choose the location where you want to create your virtual machine.
Configure the virtual machine settings, such as the size, username, and password.
Select the virtual network that you created in step 2.
Click on “Create”.

Conclusion

In this article, we walked through the steps to create a 3-tier application using Azure Virtual Machines. By following these steps, you can deploy a scalable, cloud-based application that includes a presentation tier, an application tier, and a database tier. With Azure Virtual Machines, you can easily create and manage virtual machines, storage accounts, and other cloud-based resources to support your application needs.
