In this lesson, we dive into the AWS License Manager service, which simplifies the management of software licenses across your environments—from cloud-based deployments to traditional on-premises systems. Whether you’re managing various operating systems, databases, or enterprise applications, having clear oversight of your license usage is essential to avoid costly compliance issues.
Organizations often face challenges such as a lack of visibility into license usage and entitlements. This can lead to inadvertent license violations and inefficiencies like over-purchasing licenses, which may incur unnecessary expenses.

​
The Need for Efficient License Management

Without effective license management, you risk breaching software license terms, potentially leading to fines and legal complications. Large organizations, particularly those with multiple teams and hundreds of engineers, might inadvertently purchase more licenses than needed. This creates wastage of resources and escalates costs. To tackle these challenges, AWS License Manager provides a centralized solution that manages licenses from various vendors—such as Microsoft, SAP, Oracle, and IBM—across both AWS and on-premises environments. This service not only enforces licensing rules but also tracks and reports usage to ensure compliance.
The image illustrates a "License Manager" process with four steps: defining license configurations, applying them to resources, enforcing rules, and tracking and reporting. Each step is represented by a colorful icon.

How AWS License Manager Works

The process begins with defining a license configuration that outlines your licensing terms. This configuration typically includes:
  • The number of licenses purchased
  • The scope of resources they cover (e.g., instances, cores, etc.)
  • Expiration dates for the licenses
Once these configurations are set, they are applied to your AWS resources—such as EC2 instances, RDS databases, and more. When an AWS resource is launched, License Manager evaluates the launch request against your predefined licensing rules. If a launch request violates these rules, the service can block the creation of the resource, ensuring you remain compliant.
Failure to adhere to licensing rules can result in overspending or even legal repercussions. Always verify that your resource deployment plans align with the configurations set in License Manager.
Additionally, AWS License Manager continuously monitors your license usage, producing detailed reports that help you avoid unnecessary license purchases while maintaining compliance with vendor agreements.
