Hybrid Cloud Licensing with IBM
Hybrid IT environments blur the boundaries between on-premises data centers and public clouds. IBM’s software licensing is notoriously complex, and hybrid deployments can magnify compliance challenges and costs.
This guide outlines common pitfalls and best practices to ensure your IBM licensing remains compliant and cost-effective across both on-premises and cloud environments. Read our ultimate guide to IBM Cloud Licensing Strategies: Hybrid Cloud, Reserved Capacity, and SaaS Deals.
Hybrid Scenario Overview
Using IBM software in a hybrid cloud means running some workloads on your own servers and others on public cloud infrastructure (such as AWS, Azure, or IBM Cloud) simultaneously. IBM supports this via its BYOL (Bring Your Own License) policies – if you have a valid IBM license, you can deploy the software on an Authorized Public Cloud provider under that entitlement (subject to IBM’s terms).
This flexibility allows you to shift IBM workloads to the cloud for additional capacity or migration without requiring new licenses. However, you must ensure that you’re not double-dipping – the total usage across on-premises and cloud must stay within the number of licenses you purchased.
Typically, you’ll allocate certain entitlements to cover cloud instances and others for on-prem, or move them back and forth as needed (while not running them concurrently). IBM’s licenses (under Passport Advantage) are generally portable, meaning you can reallocate software to different machines or clouds as needed.
Document any moves and ensure you’re not running the same license in two environments simultaneously, except during a temporary migration window. In summary, IBM’s hybrid licensing allows for multi-environment use, but it’s up to you to track usage and stay within the bounds of what you own.
Counting & Tracking Licenses
Accurately measuring IBM software usage in a hybrid environment is critical. IBM’s rules require deploying the IBM License Metric Tool (ILMT) for any virtualized or sub-capacity deployment.
That means even in the cloud, if you’re using your own IBM licenses on VMs, you should install ILMT (or a similar IBM-approved tool) to track how many CPU cores (PVUs or VPCs) your software is consuming. ILMT gathers data and produces reports of peak usage, which you can compare against your entitlements.
If you don’t use ILMT in a cloud deployment, IBM may assume full (unlimited) usage and could demand you license an entire cloud host – an expensive scenario.
For containerized workloads (like IBM Cloud Paks running on OpenShift or Kubernetes), use the IBM License Service. This tool runs in your cluster to monitor container-based IBM software usage, since containers can scale up and down rapidly.
The License Service is essentially mandatory for IBM products in containers, and it provides data back to prove compliance for those environments (you can integrate it with ILMT or use it standalone).
In hybrid setups, one common pitfall is the double-counting or omission of deployments.
A dynamic cloud environment might spin up an IBM server that you forget to log, or you might accidentally allocate the same license to two systems.
To prevent this, maintain a unified inventory of IBM deployments across both on-premises and cloud environments. Ensure ILMT covers all servers (on-premises and cloud VMs) in a single, consolidated report.
Automate compliance where possible – for example, include ILMT agent installation in cloud VM setup scripts so no instance goes untracked. And review your ILMT/License Service reports regularly (quarterly is a good practice).
This way, you’ll catch any under-licensing (usage beyond entitlements) early and can correct it before it becomes a serious issue.

Cloud Provider Marketplace vs BYOL
When you run IBM software on a public cloud, you have two licensing options: use your own license (BYOL) or use a license included via the cloud provider’s marketplace. BYOL allows you to apply existing entitlements (at a lower cost if you already own them), but you must track usage.
Cloud marketplace licensing means you pay for the software as part of your cloud bill (zero upfront commitment, but usually higher cost over time). The table below summarizes key differences:
Model | License & Cost Model | Notes |
---|---|---|
On-Premises | Purchase IBM software licenses (perpetual or subscription) and deploy on your servers. | Full control on-prem. Compliance is your responsibility (use ILMT for sub-capacity). |
BYOL (Cloud) | Use your existing IBM entitlements on cloud instances. Pay the cloud provider only for infrastructure (no IBM software fee). | Cost-effective if you already own licenses. Must track usage via ILMT/IBM License Service to stay compliant. |
Cloud Marketplace | Get the IBM software from the cloud marketplace with the license included in the hourly or monthly price. | Convenient for short-term needs or quick setups. Higher cost over time. Cloud provider’s billing covers the license (no ILMT needed for those instances). |
In practice, BYOL is usually best for steady, long-running workloads where you have available licenses, because you avoid the markup of pay-as-you-go rates.
Marketplace licensing is attractive for short-term or experimental projects where you don’t want to make an upfront purchase – you pay a premium for flexibility and can turn it off when you’re done.
Many organizations use a mix of both models: BYOL to minimize costs on core systems, and marketplace licenses for temporary capacity or fast deployments.
License Mobility Across Clouds
IBM licenses are generally portable across environments, which is good news for multi-cloud strategies. If you have entitlements for an IBM product, you can usually deploy that product on any of IBM’s authorized public clouds or on-prem, using the same licenses.
For example, if you bought 100 PVUs of IBM WebSphere, you could use them all on-premises, or all in AWS, or split them between environments – whatever fits your needs. You just cannot exceed the total 100 PVUs in use at any given time.
Ensure the cloud provider is on IBM’s approved list (most major ones are). Also, while licenses can move, they aren’t meant to be active in two places at once unless you own separate licenses for each.
Coordinate deployments so that if you spin up additional IBM servers in one cloud, you have enough entitlements to cover all running instances across clouds.
If you switch a workload from Azure to AWS, be sure to decommission it on Azure if you only had one license. (IBM typically allows a short overlap for migration or failover testing, but not permanent dual use of one license.)
IBM’s BYOL policy explicitly covers all the big cloud providers, so there’s no special fee to use your licenses on those platforms – it’s simply part of your entitlement.
Apart from IBM’s mainframe or certain SaaS offerings (which use different models), almost all IBM software can be deployed on any authorized cloud via BYOL.
In short, you truly have multi-cloud flexibility with IBM licenses – just stay within your license limits and keep good records of where things are running.
Compliance Tips
Staying compliant with IBM in a hybrid cloud comes down to good tracking and proactive management.
Keep these tips in mind to avoid common pitfalls:
- Maintain a Central License Inventory: Keep a single source of truth that lists all IBM products, the number of licenses you have, and their deployment locations. This visibility ensures you know what’s running and prevents any duplicate or overlooked usage.
- Use IBM’s Monitoring Tools Everywhere: Deploy ILMT on all VMs running IBM software and the IBM License Service on all OpenShift/Kubernetes clusters. These tools will alert you to under-licensing by capturing peak usage. Review their reports regularly and compare them to your entitlements to catch any overuse early.
- Separate Production and Non-Production Entitlements: If you have special lower-cost dev/test licenses or free “Developer” editions from IBM, use them only in non-production environments. Never run a production workload (on-prem or in the cloud) with a license that isn’t authorized for production use. Mixing these up is a common compliance mistake.
- Manage Disaster Recovery Properly: Document your DR setup and understand IBM’s rules. A cold standby server (powered off except during DR tests or an actual emergency) usually does not require a license until it’s activated. A hot standby (running concurrently for high availability) does require full licensing. Ensure your team understands the distinction and doesn’t inadvertently leave a DR instance running without licenses.
- Audit Yourself and Report if Needed: If your IBM agreement requires usage reporting (for example, some Cloud Pak or ELA contracts), be diligent about including cloud deployments in those reports. Even if not required, conduct periodic audits across all environments to verify usage versus entitlements and proactively true up as needed. It’s far better to identify and rectify a shortfall yourself than to have IBM discover it during an official audit.
Negotiation Tactics
Getting the most flexible and cost-effective deal from IBM is easier if you negotiate with a hybrid cloud in mind.
Here are some strategies:
- Include Hybrid Use & Mobility: Ensure your IBM contract explicitly permits using licenses on-premises and in any authorized public cloud under the same entitlements. Additionally, push for flexibility to reassign licenses across environments without lengthy waiting periods or additional approvals.
- Include Perpetual-to-SaaS Conversion Clauses: If you might switch to IBM’s SaaS or cloud services in the future, negotiate a clause that lets you convert existing licenses into credits or subscriptions. For example, have IBM agree that if you later move to an IBM Cloud Pak as a Service, you can apply the value of your current licenses toward that subscription. This prevents double-paying if you transition to cloud offerings.
- Leverage Hybrid Commitments for Discounts: When IBM knows you’re adopting a hybrid model (especially using newer offerings like Cloud Paks or IBM Cloud services), use that as leverage. IBM sales teams are keen to promote cloud adoption, so they may offer better pricing or extra entitlements if you commit to broader IBM usage across on-prem and cloud. This can translate into bigger discounts or more favorable terms if IBM sees you embracing their software in both environments.
- (Always get any special provisions documented in writing – don’t rely on verbal assurances. With well-negotiated terms, you’ll have more flexibility to optimize IBM software usage across all your environments without hidden costs.)
FAQs — IBM Hybrid Cloud Licensing
Q: Can I use the same IBM license on-prem and in AWS?
A: Yes. IBM’s BYOL policy allows it, provided the cloud is authorized and you don’t exceed your entitlements. You’ll need to track usage in both places, but a single license can cover either an on-premises instance or a cloud VM (not both at the same time).
Q: Do I need separate licenses for a disaster recovery site in the cloud?
A: Not if it’s a true cold standby (inactive except for periodic testing). Cold DR systems don’t require a license until they become active during a disaster. However, if the DR instance is running simultaneously (as a hot standby), it needs to be fully licensed, just like a production system.
Q: Does ILMT work in AWS or Azure?
A: Yes. You can install and run IBM’s ILMT on cloud instances just as on-premises. The need to track sub-capacity usage with IBM’s tools applies equally in the cloud – you should deploy ILMT (or IBM’s container License Service for Kubernetes) to monitor any BYOL deployments in AWS, Azure, etc.
Q: Are IBM products available on AWS/Azure Marketplace?
A: Yes. Many IBM software titles (databases, middleware, analytics, etc.) are offered on cloud marketplaces. You can launch an instance with the IBM software license included and pay for it as part of your cloud bill. Just note that this convenience comes at a higher hourly cost than using your own licenses (BYOL) in most cases.
Q: Which cloud providers are authorized for IBM BYOL?
A: IBM’s BYOL policy covers all major public clouds (IBM Cloud, AWS, Azure, Google, etc.). If you’re using one of the big-name providers, it’s authorized under IBM’s rules.
Q: Can IBM licenses move across multiple clouds?
A: Yes. IBM licenses aren’t tied to any single provider. As long as you use IBM-approved clouds, you can redeploy your IBM software to different clouds (or back on-prem) as needed. Just remember that one license can only cover one running instance at a time – if you switch environments, shut down the old deployment or ensure you have an extra license.

Five Recommendations — Hybrid Cloud Licensing
- Map All Hybrid Deployments: Maintain a clear inventory of all IBM software instances, both on-premises and in each cloud. This visibility ensures you know what’s running and prevents any gaps or double allocation of licenses.
- Choose BYOL vs. Marketplace Wisely: Evaluate costs and compliance implications for each workload. Use BYOL to save on long-running systems if you have entitlements, and reserve marketplace (license-included) instances for short-term or unpredictable needs where buying a license isn’t feasible.
- Deploy ILMT & License Service: Make IBM’s own license tracking tools mandatory in your hybrid environment. Install ILMT on all relevant VMs and IBM License Service on container clusters to automatically monitor usage. These tools are crucial for staying compliant with IBM’s sub-capacity rules.
- Negotiate for Flexibility: In your IBM contracts, include rights to use licenses in hybrid cloud environments and to swap them between on-premises and cloud environments without hassle. Also, secure options to convert licenses to IBM’s SaaS offerings if needed. This contractual flexibility will save costs and headaches in the future.
- Audit Continuously & Educate Teams: Conduct periodic self-audits of IBM software usage across all environments. Train your IT and DevOps teams about IBM licensing basics so they don’t accidentally deploy software without proper entitlements. Being proactive and spreading awareness helps prevent compliance issues before they start.
