SQL Server Express Edition can be used for commercial purposes under its licensing terms. However, it is important to note that SQL Server Express has certain limitations, such as database size restrictions and lack of support for some advanced features that are available in other editions of SQL Server.
As for additional licenses or conditions, SQL Server Express is designed to be free to use, but you should ensure that your usage complies with the specific licensing terms provided by Microsoft. It's advisable to review the official licensing documentation or consult with Microsoft directly for any specific conditions that may apply to your use case, especially since you are deploying it in a cloud environment like AWS EC2.
