MSFTCOST03-BP01 Understand Microsoft SQL Server licensing and BYOL availability
AWS offers a range of flexible cost optimization choices for licensing. These licensing options are designed to help you reduce costs, maintain compliance, and meet your business needs. AWS offers the license include option, which you can launch Windows EC2 instances with SQL Server installed and licensed on-demand, paying only for what you use. With the right requirements, you can also bring your own licenses to AWS, either to Amazon EC2 Dedicated Hosts or default (shared) tenancy.
Desired outcome: Optimize costs by thoroughly evaluating Microsoft SQL Server licensing options on AWS, including both the license-included model for on-demand usage and the Bring Your Own License (BYOL) approach for either Amazon EC2 Dedicated Hosts or default shared tenancy, ensuring that the chosen licensing strategy aligns with compliance requirements, maximizes cost savings, and effectively supports business objectives through AWS's flexible licensing framework.
Common anti-patterns:
-
Automatically defaulting to license-included instances without analyzing BYOL cost benefits, potentially missing out on significant savings from existing Microsoft Enterprise Agreements or Software Assurance benefits that could be leveraged on AWS.
-
Failing to properly track and document SQL Server deployments across different AWS environments, leading to over-provisioned licenses or compliance risks from unintentionally running SQL Server workloads on shared tenancy when BYOL requires dedicated hosts.
-
Choosing licensing models based solely on immediate costs without considering long-term implications, such as selecting on-demand licensing when workloads are actually stable and predictable, resulting in higher total cost of ownership compared to BYOL options.
Benefits of establishing this best practice:
-
Significant Cost Optimization: By carefully evaluating and implementing the most appropriate licensing model (BYOL versus license-included), organizations can achieve substantial cost savings through efficient license utilization, maximizing existing investments in Microsoft agreements, and aligning licensing costs with actual usage patterns.
-
Enhanced Compliance and Risk Management: Proper licensing practices ensure continuous compliance with Microsoft's licensing terms and AWS's infrastructure requirements, reducing the risk of audit findings, unexpected true-up costs, and potential penalties while maintaining clear documentation of license deployment and usage.
-
Improved Operational Flexibility: Understanding and implementing the right licensing strategy enables organizations to scale their SQL Server workloads more effectively, choose the most cost-effective deployment options (dedicated hosts versus shared tenancy), and maintain the agility to adjust licensing approaches as business needs evolve.
Level of risk exposed if this best practice is not established: Medium
Implementation guidance
To implement effective Microsoft SQL Server licensing on AWS, start by inventorying existing licenses and analyzing workload patterns to determine the most cost-effective option between BYOL and license-included models. Establish clear documentation and tracking processes using AWS License Manager, and implement regular reviews to optimize costs while maintaining compliance with both Microsoft and AWS requirements.
Implementation steps
-
Conduct a comprehensive inventory of existing SQL Server licenses and associated rights (AWS OLA can be useful as well).
-
Analyze workload characteristics and usage patterns to determine the most cost-effective licensing model (BYOL versus license-included).
-
Set up AWS License Manager to track and manage SQL Server deployments across your AWS environment.
-
Implement a tagging strategy to accurately monitor and allocate SQL Server licensing costs.
-
Establish a regular review process to optimize licensing strategy and ensure ongoing compliance with Microsoft and AWS requirements.
