In the context of AWS and preparing for the AWS Certified Cloud Practitioner (CLF-C02) exam, one of the critical areas of focus is license management. Specific attention should be to different licensing strategies such as the Bring Your Own License (BYOL) model and included licenses model.
Bring Your Own License (BYOL) Model
The Bring Your Own License (BYOL) model, as the name implies, allows users to bring their existing software licenses to the cloud environment. This model ensures that organizations can transition to the cloud effortlessly, without needing to repurchase the software licenses.
BYOL is a model supported by AWS and it offers flexibility and cost-saving potential. If your organization already owns licenses for a specific software, you can continue using that software on AWS without incurring additional license costs.
However, BYOL also comes with some challenges. The primary one being specific software licenses are potentially not eligible to be moved onto a cloud environment due to contractual limitations or other stipulations in the End User License Agreement (EULA).
Included Licenses Model
On the other hand, the included licenses model, also known as License Included (LI), is a model where the user obtains the license for the software directly from AWS when they launch an instance. This model means that the customer does not need to own any existing licenses – it’s all bundled into the service provided by AWS.
The primary benefit of the LI model is its simplicity and its ability to start using a software immediately in the cloud. This model saves the users from the complexity of managing and complying with software licenses.
On the downside, the Included Licenses model could be more expensive in the long term if the software is to be used extensively and over a long period, as licensing fees are built into the cost of the instance.
BYOL vs Included Licenses Model: A Comparison
Here is a table to compare the two licensing models:
| BYOL | Included Licenses Model | |
|---|---|---|
| Advantages | Use existing licenses, potentially lower costs | Simplicity, immediate usage |
| Disadvantages | Contractual restrictions, complex management | Potential higher long-term cost |
| Best for | Companies with existing extensive licenses | Startups, small projects |
When deciding which licensing model to use, some factors to be examined are the existing licenses portfolio your organization holds, the financial implications of both models, and the potential administrative overhead of managing licenses in a BYOL model.
It’s essential to understand these licensing models’ differences when working on AWS, whether you are pursuing the AWS Certified Cloud Practitioner certification or aiming to optimize your organization’s cloud deployment strategies.
Both BYOL and Included Licenses Model have their respective pros and cons. The decision going for any of these models is ultimately depends on the business use case and requirements.
To stay within the legal boundaries and ensure efficient use of resources, organizations should deeply analyze and consider these licensing strategies in their cloud journeys. AWS provides tools and services to assist in this analysis and ensure that licenses are managed correctly in either scenario.

Interview Questions
What is a Bring Your Own License (BYOL) model in AWS?
BYOL model allows customers to use their already owned software licenses in the AWS Cloud. Users can bring their existing software licenses to AWS and run them on Amazon EC2 or Amazon RDS, subject to compliance with existing licensing terms.
How is BYOL model different from the included license model?
In the included license model, AWS provides the software license as a part of the service. While in BYOL, customers themselves are responsible for the software license as they are bringing their own.
What can you do with the BYOL model in AWS?
With BYOL, you can fully utilize perpetual software licenses that you already own while migrating to AWS Cloud. It avoids unnecessary software licensing costs when migrating to the cloud.
Can you use Microsoft Windows licenses in BYOL model?
Yes, you can use your existing Microsoft Windows Server and Microsoft SQL Server licenses with BYOL model subject to Microsoft’s licensing terms and conditions.
What services does AWS offer with included licenses?
The services like Amazon RDS for Oracle, Amazon RDS for SQL Server, Amazon RDS for PostgreSQL, Amazon RDS for MySQL, and Amazon RDS for MariaDB include the software licenses in their pricing.
How is cost-effectiveness maintained with the BYOL model in AWS?
The BYOL model can be cost-effective as customers can leverage their pre-existing licenses and avoid paying additional fee for the license included model.
What is AWS License Manager?
AWS License Manager is a service that simplifies the management of your software licenses from various software vendors such as Microsoft, SAP, Oracle, and IBM across AWS and on-premises environments.
How can you ensure compliance with BYOL model on AWS?
Using AWS License Manager can ensure compliance in the BYOL model. It sets rules based on your licensing agreements, and prevents any over-usage thereby maintaining license compliance.
Is there a performance difference between the BYOL and License included model?
There shouldn’t be any significant performance difference between the two models because performance is more dependent on the instance type and size chosen. The licensing model primarily affects the cost and legal compliance.
Is there a certain time period for using the BYOL model in AWS?
No, there is no set time period for BYOL in AWS. You can continue to use it as long as you comply with the terms of the software license and it is supported by AWS.
Can you convert between BYOL model and license included model and vice versa in AWS?
Yes, you can switch between the models. However, software licensing terms and cost implications must be considered when making the switch.
Where can you use BYOL model in AWS?
The BYOL model can be used in a variety of AWS offerings such as Amazon EC2 and Amazon RDS, amongst others.
Is it possible to use a combination of BYOL and License included models in AWS?
Yes, it is possible to mix BYOL with license included depending on your workloads and licensing agreements. The AWS License Manager can help in tracking and managing these licenses.
What type of licensing is available for AWS Marketplace products?
Licensing for AWS Marketplace products can either be provided by the seller or you may be able to bring your own license, depending on the product.
Can all software licenses be used in a BYOL model in AWS?
It depends on the terms of the software license. Not all licenses permit use in the cloud, so you should check with your software vendor before implementing BYOL in AWS.
