SQL Server on Azure VMs is a powerful solution that allows you to run SQL Server inside a virtual machine in the cloud. This falls into the category of Infrastructure-as-a-Service (IaaS), where you can leverage the benefits of cloud computing while running SQL Server.

When using SQL Server on Azure VMs, you have the flexibility to choose between paying for a SQL Server license included in a SQL Server image or using your existing license. Microsoft provides a range of platform-provided SQL Server images that include a license, or you can bring your own SQL Server license. This means that you can use any supported SQL Server version and edition, including 2008R2, 2012, 2014, and 2016, with options like Developer, Express, Web, Standard, and Enterprise editions.

The cost of using SQL Server on Azure VMs depends on various factors. If you choose to use the Azure provided images, the operational cost is determined by the VM size and the edition of SQL Server you select. You pay a per-minute licensing cost for SQL Server and the Windows or Linux Server, along with the Azure Storage cost for the VM disks. This per-minute billing option allows you to use SQL Server for as long as you need without having to purchase additional SQL Server licenses.

If you bring your own SQL Server license to Azure, you are only charged for the server and storage costs. This can be a cost-effective option if you already have a SQL Server license and want to take advantage of the benefits of running SQL Server on Azure VMs.

To estimate the cost of SQL Server on Azure VMs, Microsoft provides the Azure Pricing Calculator. This tool allows you to understand the costs of moving your technical estate to Azure and estimate pricing once your data and applications are in Azure. You can input the details of your Azure Virtual Machines, such as CPU, memory, storage, location, and hours in use, and the calculator will provide you with an estimate of the pricing for your complete solution.

When using the Azure Pricing Calculator, you can select the virtual machine specifications that match your requirements. It is important to correctly size your VM, as the licensing cost of SQL Server is directly related to the number of vCPUs. You can also choose the billing option that suits your needs, whether it’s regular per-second billing or pre-paying for the instance for 1 or 3 years to receive a discount. Additionally, you can configure the type of storage used for the virtual machine, including options for managed OS disks and snapshots.

Once you have selected all the required fields, you can export, save, or share the estimated prices for your virtual machine. This allows you to make informed decisions about the costs of running SQL Server on Azure VMs and plan your budget accordingly.

By understanding the costs associated with SQL Server on Azure VMs, you can effectively manage your expenses and optimize your resources. Whether you choose to use the Azure provided images or bring your own SQL Server license, running SQL Server on Azure VMs offers a flexible and scalable solution for your database needs.
