It opens avenues to move beyond conventional Microsoft-licensed products, embracing specialized cloud-based technologies. This shift provides a way out from the constraints and high expenses tied to Microsoft licensing.

## 2. Can your existing Microsoft licenses migrate to AWS?

Bringing existing Microsoft licenses to AWS, known as Bring Your Own License (BYOL), is a powerful option. As a Microsoft License Mobility Partner, AWS enables the transfer of licenses like SQL Server with active software into their cloud environment on Amazon EC2. BYOL allows businesses to leverage cloud benefits while retaining current licensing investments and unlocking significant savings in licensing costs.

Explore the Microsoft licensing FAQ provided by AWS. It offers a valuable resource for gaining a deeper understanding of Microsoft licensing on the AWS platform. Moreover, AWS offers a complimentary service known as the Optimization and Licensing Assessment (AWS OLA), designed to refine both your on-premises and cloud environments. This service guarantees that you only pay for the resources you utilize, all while ensuring adherence to third-party licensing compliance.

## 3. How can you reduce dependency on Microsoft licensing with AWS?

Many new and experienced customers are actively looking for ways to break free from the constraints and high costs associated with Microsoft licensing.

The overarching objective is to reduce expenses, enhance security, and maximize the cost-effectiveness of Microsoft applications. 

AWS empowers a faster pace of innovation by offering alternatives to Microsoft-licensed products through the integration of open-source options and cloud-optimized technologies. This shift can result in notable enhancements in project speed and overall efficiency. Consider implementing the following strategies:

- **Transition from Windows Server to Linux:** Embrace a more flexible and cost-effective operating system to optimize your resources.
