IBM WebSphere Licensing: Key Models and Best Practices

IBM WebSphere licensing works through various models, each tailored to different user and deployment needs:

  • Authorized User Model: For designated individual users, allowing access on multiple machines.
  • Concurrent User Model: Based on the number of users accessing the software simultaneously.
  • Floating Licenses: Shared among a group, limiting concurrent use to the number of licenses purchased.
  • Resource Value Unit (RVU): Based on the usage of specific resources by the software.
  • Processor Value Unit (PVU): Depends on the server’s processor type and the number of cores.

The IBM WebSphere Hybrid Edition is a pivotal offering in IBM’s licensing portfolio, representing a significant shift towards flexible, cloud-centric environments.

  • Purpose and Introduction: The Hybrid Edition consolidates various WebSphere offerings into a unified, versatile platform, addressing the demand for containerized and microservices-oriented architectures.
  • Components and License Entitlement: This edition encompasses components like WAS Network Deployment, Liberty application servers, and Cloud Foundry Migration Runtime, offering a comprehensive solution for both traditional and modern applications.
  • Comparative Analysis with IBM Cloud Pak: While sharing similarities with the IBM Cloud Pak for Applications, the Hybrid Edition distinguishes itself by focusing more on the flexibility of deployment options and modernization of legacy applications.

Types of IBM Licensing Models

IBM’s licensing models are designed to accommodate diverse business needs, offering various options to optimize software investments and usage.

Understanding these models is crucial for effective software management.

Authorized User Model

  • Definition: The Authorized User model grants access to a designated individual. This user can access the software on multiple machines but cannot share their license with others.
  • Scenario: Ideal for a specific employee needing dedicated software access across multiple devices.
  • Key Point: Each Authorized User requires a separate license, ensuring personalized access without the ability to share or transfer except in permanent cases like employee turnover​​.

Concurrent User Model

  • Definition: This model is based on the number of users accessing the software at any given time, not the total number of users.
  • Scenario: Suitable for environments where users access the software in shifts, like a 24/7 operation with different staff working at different times.
  • Key Point: It’s essential to license for the maximum number of users that might access the software simultaneously​​.

Floating Licenses

  • Definition: Floating licenses are shared among a group of users. They limit the concurrent use to the number of purchased licenses.
  • Scenario: Useful in teams where software usage is intermittent and can be scheduled.
  • Key Point: If all licenses are in use, additional users must wait for a license to become available before accessing the software​​.

Resource Value Unit (RVU) and Processor Value Unit (PVU)

  • RVU: RVU licenses are based on the usage of specific resources by the software. It’s tailored to the intensity and scale of software use.
  • PVU: PVU licensing depends on the type of processor and the number of cores on the server hosting the software. It’s ideal for scaling with hardware capacity.
  • Scenario for RVU/PVU: These models are best for high-intensity software applications in server environments where scaling up resources is a frequent need​

IBM Software License: Perpetual and Time-Limited

The distinction between perpetual and time-limited licenses is fundamental for long-term software planning and budgeting.

Perpetual Licenses

  • Nature: Perpetual licenses allow indefinite use of the software from the point of purchase.
  • Advantages: Offers long-term stability without the need for regular renewals. However, support and updates might require an active Software Subscription and Support (S&S) contract.
  • Passport Advantage Program: This program offers perpetual licenses, providing rights to use the software indefinitely, but updates and support might be contingent on S&S renewal​​.

Time-Limited Licenses

  • Nature: These licenses are valid for a specified duration, often accompanied by support and updates.
  • Advantages: Ideal for short-term needs or testing the software before a long-term commitment.
  • Renewal and Support: Time-limited licenses often require renewal for continued use and access to support.

Insights into IBM’s Passport Advantage Program

  • Structure: The Passport Advantage program encompasses perpetual and time-limited licensing options, offering flexibility based on organizational needs.
  • Software Subscription and Support (S&S): This component is crucial for perpetual licenses, offering access to the latest updates and technical support. S&S is usually available for an initial 12-month period, with renewal options​.
