What Are IBM Middleware Products?

IBM middleware products are software solutions that provide a layer of functionality to help diverse applications communicate, manage data, and perform various tasks efficiently.

Common IBM middleware products include:

• IBM WebSphere Application Server: A robust Java-based application server hosting web applications.
• IBM MQ (Message Queue): A messaging middleware used to ensure secure, reliable communication between applications.
• IBM Integration Bus (IIB): Now known as IBM App Connect Enterprise, it integrates various services and applications.
• IBM DB2: A database management system that helps store and retrieve data effectively.

These tools connect and integrate diverse applications, making them fundamental to business processes.

Types of IBM Licensing Models for Middleware

IBM offers multiple licensing models to address various businesses’ needs. The main types of licensing models for IBM middleware products are:

1. Processor Value Unit (PVU) Licensing
2. Authorized User Licensing
3. Floating User Licensing
4. Monthly Licensing

Let’s take a closer look at each:

1. Processor Value Unit (PVU) Licensing

Processor Value Unit (PVU) licensing is one of the most common models for IBM middleware. It is based on the processing power available to the product. Here’s how it works:

• Definition: A PVU is a unit of measure used to differentiate licensing costs based on the server’s processing power.
• Example: Suppose you have an IBM WebSphere Application Server installed on a server with 4 CPUs, each with four cores. The PVU requirements will depend on the type of processor being used and are determined based on the IBM PVU table, which assigns PVUs per core based on processor type (e.g., Intel, AMD).
• Use Case: This model is most suitable for enterprises with scalable environments, as PVU licensing allows for growth, but it also requires careful monitoring of CPU configurations to maintain compliance.

2. Authorized User Licensing

Authorized User Licensing is applicable where users have specific access to an IBM product.

• Definition: Under this model, each user who accesses the software needs a license.
• Example: Suppose your team uses IBM MQ for messaging services, and you have 20 employees who require access to this service. You would need 20 Authorized User licenses.
• Benefits: Ideal for organizations where a specific number of people access the software. It provides predictable pricing and easier compliance.

3. Floating User Licensing

Floating User Licensing is designed for businesses with users who need occasional access to the software.

• Definition: The license is assigned to a concurrent user, meaning that users can have access, but only a limited number can use it simultaneously.
• Example: Imagine your business uses the IBM Integration Bus (IIB) for development and testing. If ten developers share 5 Floating User licenses, up to 5 developers can use the product simultaneously.
• Flexibility: This model is a cost-effective option for businesses with multiple users that do not need full-time access to IBM software.

4. Monthly Licensing

Monthly Licensing allows organizations to license software on a subscription basis.

• Definition: Instead of purchasing perpetual licenses, businesses pay a monthly fee to use the product.
• Example: If you use IBM WebSphere but prefer not to commit to a large upfront cost, you can opt for monthly licensing. This allows for budget flexibility.
• Best Suited For: Businesses that need to control costs and want the ability to scale quickly without the burden of perpetual licensing.

Key Licensing Considerations for IBM Middleware

Licensing IBM middleware comes with some critical factors that you should consider to ensure compliance and efficiency:

1. Understand Software Bundles

IBM often provides middleware products as part of bundles or suites. For example, IBM Cloud Pak for Integration includes WebSphere, MQ, IIB, and additional integration capabilities.

Bundles can offer value by simplifying purchasing decisions, but it’s crucial to understand which components are included and their licensing requirements.

2. Compliance Is Key

Compliance is often a challenge for organizations using IBM software. Non-compliance can lead to penalties, fines, and additional costs.

• Tracking Usage: Use tools like IBM License Metric Tool (ILMT) to track PVU usage and stay compliant.
• Example: Consider a scenario where your company uses IBM WebSphere across multiple servers. ILMT helps ensure you only use the licensed number of PVUs, preventing unwanted surprises during an IBM audit.

3. Capacity Planning

For PVU-based licensing, managing server capacity effectively is critical to avoid over-licensing or under-licensing.

• Example: If you are scaling your server capacity during peak business hours, ensure you have enough licenses for the additional CPUs. Scaling down without de-allocating licenses can lead to unnecessary costs.

Licensing WebSphere Application Server

IBM WebSphere Application Server (WAS) is one of IBM’s most popular middleware products. Licensing WebSphere can be complex, depending on the edition and deployment model:

• Editions Available: WebSphere is available in multiple editions—Network Deployment (ND), Liberty, and Base. Each has different capabilities and corresponding pricing.
• Example: If you’re running WebSphere Application Server Liberty on a development environment, you may need to check if the usage qualifies under the IBM Cloud Pak licensing, which provides more flexibility in the development and testing stages.

Licensing IBM MQ

IBM MQ is another frequently used middleware solution, and its licensing depends largely on usage:

• Options Available: IBM MQ can be licensed by PVUs or using Managed File Transfer licensing. The licensing model to choose depends on whether it’s deployed on-premises or in the cloud.
• Example: Suppose you have an IBM MQ installation across three servers, each with different processing powers. PVU-based licensing would mean calculating the PVUs for each server, while an as-a-service licensing model could simplify this, particularly in cloud deployments.

IBM Middleware in the Cloud: Licensing Considerations

IBM’s push towards hybrid cloud solutions means middleware licensing has evolved to accommodate cloud deployment. IBM Cloud Pak is a key product offering here, which provides simplified licensing for middleware products in the cloud environment:

• Cloud Pak for Integration: This includes WebSphere, MQ, and App Connect with container-based licensing, which makes it easier to track usage in a dynamic environment.
• Example: With IBM Cloud Pak, instead of dealing with PVUs, you can license based on Virtual Processor Cores (VPCs). This works well if you deploy IBM MQ in a Kubernetes cluster where workloads may vary.

IBM License Metric Tool (ILMT)

The IBM License Metric Tool (ILMT) is essential for tracking PVU usage and maintaining compliance for IBM products.

• Usage Requirement: IBM requires ILMT for clients using PVU-based licensing in virtualized environments to ensure that they only use the number of PVUs they’ve paid for.
• Benefits: By automating usage data tracking, ILMT helps organizations stay compliant and avoid the hefty fines that can result from an IBM audit.

Best Practices for Licensing IBM Middleware

To manage IBM middleware licensing effectively, consider the following best practices:

• Assess Licensing Requirements Early: Before deploying any IBM middleware product, assess your infrastructure needs and user requirements to choose the most cost-effective licensing model.
• Use Bundled Offerings When Possible: Products like IBM Cloud Pak may reduce overall costs by providing access to multiple middleware components under one licensing model.
• Regularly Monitor Compliance: Use ILMT or similar tools to monitor compliance and avoid licensing risks.
• Review Contracts and Renewals: Ensure you’re clear about the renewal terms and the specific clauses in IBM contracts, as they can impact your long-term expenses.

Examples of Cost Optimization

Cost optimization in IBM licensing can help businesses save significant money. Here are some real-world scenarios:

• Example 1: Suppose an enterprise has multiple environments (production, testing, development) running IBM WebSphere. Using IBM Cloud Pak for Integration might help cut costs by avoiding individual licenses for each environment.
• Example 2: For a company with many part-time developers, Floating User Licensing can be more economical than Authorized User Licensing, as the license count is based on concurrent usage rather than total users.
