In the below mentioned previous post, we have discussed about different installation options available for SQL Server on Azure VM
Different Installation Options Available for SQL Server on Azure VM
It is important to understand the differences in the three option mentioned in the above post.
– Create a SysPreppedImage of the SQL Server version of our choice on an hyper-v VM on out local environment and then Upload it to Azure.
– Create a virtual machine running Windows from the Azure portal and then install SQL Server on it.
– Provision a SQL Server virtual machine in Azure from the Azure portal.

SysPreppedImage of the SQL Server on Hyper-V VM and Upload to Azure is preferred when you want to use your own licenses for Windows Operating System and SQL Server, so that you only need to pay for Azure compute and storage costs incurred for hosting your VM with SQL Server on Azure. Since SQL Server 2008 R2, has introduced of performing a SysPrep image, and the steps are simple. In this DBAs can choose and install required SQL Server versions and patches and required Operating System versions and patches instead of depending up on the versions provided by Microsoft Azure. However this is the most time consuming task of the three methods as this involves buinding hyper-v VM and preparing SQL Server SysPrep image and then uploading the VHD files to the Azure and then use it to create the VM. This is preferred when you want to use your own licenses which you are have, to avoid using Microsoft licensing available for Windows OS and SQL Server from Microsoft on per-minute usage basis.

Create a virtual machine running Windows is preferred you want to use your own license of SQL Server, but use the license of Windows Operating System provided by Microsoft, however the licensing of the Windows OS usage, compute and storage usage of Azure VM are calculated on the per-minute basis. SO, In this case, we pay only for the per-minute for the Azure Compute, Storage, and Windows license but not for the SQL Server license. In this DBAs can choose and install required SQL Server versions and patches. This involves additional work of installing SQL Server, its patches.

Provision a SQL Server virtual machine in Azure is preferred when you do not want to use any of your own licenses, instead only want to dependent or use the Microsoft licenses, but this usage is mostly calculated on per-minute basis. In this we need to pay per-minute for a SQL Server license along with an Azure Compute, Storage, and Windows license. This allows us to install SQL Server at desired version and service pack level, thus reducing the time taken for SQL Server installation along with VM setup and these things can be done from Azure portal with simple clicks and providing the options. This is best suited for applications which are required for short time for testing and later can be shutdown, thus brings down the cost.

Hope this was helpful.

This is applicable for below versions of SQL Server

SQL Server 2008 R2
