When companies move to AWS, they often have existing licenses for software like Microsoft Windows Server, SQL Server, Oracle databases, or other enterprise applications. Instead of purchasing new cloud-specific licenses, BYOL enables them to transfer these licenses to their cloud infrastructure.
Key benefits of BYOL include:
1. **Cost Optimization**: Organizations can leverage existing license agreements and avoid paying for new licenses, reducing overall cloud expenses.
2. **License Flexibility**: Companies maintain control over their licensing terms and can continue using familiar software configurations.
3. **Compliance**: BYOL helps organizations stay compliant with their existing software agreements while transitioning to the cloud.
AWS supports BYOL through several mechanisms:
- **Amazon EC2 Dedicated Hosts**: These provide physical servers dedicated to your use, making it easier to use existing server-bound licenses that require visibility into physical cores and sockets.
- **Amazon EC2 Dedicated Instances**: These run on hardware dedicated to a single customer, supporting certain licensing requirements.
- **AWS License Manager**: This service helps manage software licenses from vendors like Microsoft, SAP, and Oracle across AWS and on-premises environments.
Important considerations for BYOL:
- Verify license terms with your software vendor to ensure cloud deployment is permitted
- Understand which AWS deployment options satisfy your licensing requirements
- Track license usage to maintain compliance
- Consider the total cost comparison between BYOL and AWS-provided licensing options
BYOL is particularly valuable for enterprises with significant existing software investments, helping them optimize their cloud migration strategy while maintaining licensing compliance and controlling costs.
BYOL, or Bring Your Own License, is a licensing model that allows organizations to use their existing software licenses when deploying workloads on AWS. Instead of purchasing new licenses through AWS, customers can transfer their current on-premises licenses to the cloud, potentially saving significant costs.
Why is BYOL Important?
Understanding BYOL is crucial for several reasons:
• Cost Optimization: Organizations with existing license agreements can avoid paying for duplicate licenses when migrating to AWS • Investment Protection: Companies can leverage their previous software investments rather than abandoning them • Compliance: Proper license management ensures organizations remain compliant with software vendor agreements • Flexibility: BYOL provides options for how businesses consume software in the cloud
How BYOL Works on AWS
1. License Eligibility: First, verify that your existing licenses are eligible for cloud deployment. Check your license agreement terms with the software vendor.
2. Dedicated Hosts or Dedicated Instances: Many BYOL scenarios require Amazon EC2 Dedicated Hosts or Dedicated Instances to meet licensing requirements. Dedicated Hosts provide physical servers dedicated to your use, giving you visibility into sockets and cores for license tracking.
3. AWS License Manager: AWS provides License Manager to help track, manage, and control license usage across AWS and on-premises environments.
4. Common BYOL Software: Microsoft Windows Server, Microsoft SQL Server, Oracle Database, and other enterprise software commonly support BYOL arrangements.
BYOL vs. License Included
• BYOL: You provide the license; typically lower hourly costs but requires license management • License Included: AWS includes the license cost in the instance pricing; simpler but potentially more expensive if you already own licenses
Key AWS Services for BYOL
• EC2 Dedicated Hosts: Physical servers for license compliance requiring socket or core visibility • AWS License Manager: Centralized license tracking and management • AWS Migration Hub: Helps plan migrations including license considerations
Exam Tips: Answering Questions on Licensing Strategies (BYOL)
• When a question mentions existing software licenses or current license agreements, think BYOL
• Questions about reducing licensing costs during migration often point to BYOL as the answer
• If a scenario requires per-socket or per-core licensing, remember that EC2 Dedicated Hosts provide this visibility
• AWS License Manager is the service for tracking and managing licenses across environments
• Remember that BYOL requires verification of license terms with the original software vendor
• Questions comparing costs between BYOL and License Included models typically favor BYOL when the customer already owns valid licenses
• Dedicated Hosts are more expensive than shared tenancy but necessary for certain BYOL compliance requirements
• If a question asks about Microsoft or Oracle licensing in AWS, BYOL with Dedicated Hosts is often relevant
Common Exam Scenarios
• A company wants to migrate to AWS while using their existing Windows Server licenses - Answer: BYOL with Dedicated Hosts
• An organization needs to track license usage across hybrid environments - Answer: AWS License Manager
• A business wants to reduce costs by leveraging existing enterprise software investments - Answer: BYOL strategy
