Avoid using names like 'Admin' for an Azure SQL Server Active Directory Administrator account

Configure one Azure Active Directory account, either an individual or Network Security Group account, as an administrator. It is not necessary to configure an Azure AD administrator, but an Azure AD administrator must be configured if you want to use Azure AD accounts to connect to SQL Databases.It is recommended to avoid using names like 'admin' or 'administrator', which are targeted in brute force dictionary attacks.

SQL Server on Virtual Machines

SQL Server on Azure virtual machines enables you to use full versions of SQL Server in the Cloud without having to manage any on-premises hardware. SQL Server VMs also simplify licensing costs when you pay as you go.

Azure virtual machines run in many different geographic regions around the world. They also offer a variety of machine sizes. The virtual machine image gallery allows you to create a SQL Server VM with the right version, edition, and operating system. This makes virtual machines a good option for a many different SQL Server workloads.
