AWS maintains and regularly updates the SQL Server image, ensuring it is fully patched. When you launch an instance from this image, you can use it as a database server without the need for manual SQL Server software installation. This image also includes various pre-installed software and drivers, such as AWS Systems Manager, AWS CloudFormation, AWS Tools for Windows PowerShell, network drivers, and storage drivers.
To simplify the process of sizing, configuring, and deploying SQL Server applications on AWS, you can utilize AWS Launch Wizard. Launch Wizard for SQL Server is specifically designed to assist with both single-instance and high-availability deployments, following AWS and SQL Server best practices.
