Deploying IBM Software on Major Public Clouds
IBM's Bring Your Own Software Licence (BYOSL) policy allows customers to use existing IBM licences on approved public cloud infrastructure — termed "Eligible Public Clouds." Each cloud provider has specific mechanisms to support IBM software:
AWS has a close alliance with IBM, making dozens of IBM products available through AWS Marketplace. Customers can use BYOL or pay-as-you-go licences. The 2024 partnership expansion streamlined procurement globally, letting customers apply AWS enterprise spend commitments toward IBM usage. Deploy IBM WebSphere, Db2, and more on EC2 instances — but compliance tracking remains the customer's responsibility.
IBM software is available on Azure Marketplace including IBM MQ, Db2, and Cloud Pak offerings. Listings support BYOL using Passport Advantage entitlements. IBM is a multi-year Microsoft Partner of the Year award winner. Azure's hybrid benefit doesn't directly apply to IBM, but IBM's own BYOL policy covers Azure usage. IBM licences remain separate assets — not included in standard Azure fees unless purchased as a marketplace transaction.
GCP is an approved environment for IBM BYOL. Some solutions (QRadar, database offerings) are on Google Cloud Marketplace. GCP typically requires BYOL for IBM software — fewer pay-as-you-go options compared to AWS/Azure. If running Db2 or WebSphere on GCP, customers must use existing IBM licences. Treat GCP VMs like on-prem servers regarding licence tracking.
IBM's own cloud fully supports IBM software with the smoothest alignment. Many products are offered directly as cloud services with licensing included in the service fee. For self-provisioned VMs on IBM Cloud, you must apply your own licence (BYOL). IBM Cloud is sometimes chosen for IBM workloads due to deep integration and migration incentives, but most CIOs treat it as one of multiple cloud options.
VM-Based vs Container-Based Licensing
Container licensing requires setup: Deploy IBM's License Service in your cluster, and ensure you have a container licensing addendum with IBM if your Passport Advantage agreement is older. Container orchestrators spread workloads across nodes — manual counting is impossible. The automated IBM License Service is the only realistic way to prove sub-capacity compliance.
IBM's Cloud-Friendly Programmes
Containerised bundles of IBM software certified to run on Red Hat OpenShift. Each Cloud Pak focuses on a domain — Data, Integration, Business Automation, etc. — combining multiple IBM products needed for that area.
Under BYOL, organisations use existing IBM Passport Advantage entitlements on cloud infrastructure. Any IBM software acquired through Passport Advantage can be deployed on Eligible Public Clouds as long as you adhere to the terms.
Extends IBM Cloud services to run in any environment — on-prem data centres, edge locations, or other public clouds — with a single IBM Cloud control plane.
Beyond BYOL, IBM offers pay-as-you-go and SaaS offerings via cloud marketplaces — acquire software and pay based on usage (hourly/monthly), rolled into your cloud bill.
Licence Metrics: PVU vs VPC in the Cloud
📊 Processor Value Unit (PVU)
Older metric based on processor performance. IBM assigns a PVU rating per core by processor model (e.g., Intel Xeon ~70 PVUs, IBM POWER ~120 PVUs). In public clouds, IBM typically provides default PVU per vCPU — commonly 70 PVUs per vCPU on x86 clouds.
Cloud calculation: A product requiring 280 PVUs = 4 vCPUs (4 × 70). Requires referencing IBM's hardware PVU tables. More powerful cores cost more (higher PVU). Compliance is "trust but verify" — declare usage and stay compliant even though you can't inspect physical CPUs.
📊 Virtual Processor Core (VPC)
Newer metric aligned with virtual cores. 1 VPC = 1 vCPU (or 1 physical core). Processor type is irrelevant — straight count of cores allocated to IBM software. No hardware PVU tables needed.
Cloud-native simplicity: An AWS vCPU or Azure vCore is simply 1 VPC. Cloud Paks exclusively use VPC. Many newer IBM products offer VPC as alternative to PVU. IBM has conversion programmes to swap PVU entitlements to VPC for ease of cloud use.
Other metrics to track: User/Client-based licences (e.g., Cognos Analytics authorised users — doesn't change in cloud), Resource Value Units (RVU) tied to managed clients, database records, or data volume (same concept in cloud but units may be ephemeral). All require robust asset management.
BYOL vs IBM SaaS: Choosing the Right Model
Many companies adopt a hybrid approach: self-managing core custom systems via BYOL while using SaaS for commodity tools like Planning Analytics or MaaS360. IBM sometimes offers "BYOL to SaaS" conversion programmes where existing licences provide discounts on SaaS subscriptions.
Hybrid & Multi-Cloud Considerations
🔄 Consistency Across Environments
Adopt Red Hat OpenShift and IBM Cloud Paks as standard platforms for IBM workloads — they run uniformly on internal clusters, AWS ROSA, and Azure Red Hat OpenShift. IBM Cloud Satellite adds single-pane management across all environments. Standardising on consistent platforms avoids vendor lock-in and simplifies workload portability.
📡 Data Integration & Latency
Hybrid deployments often split IBM components across locations. Design architecture to handle latency and bandwidth constraints. IBM Cloud Satellite can place services closer to data sources. Map which IBM components should go to cloud vs remain local, then use IBM's hybrid tools to bridge them effectively.
🌐 Multi-Cloud Workload Distribution
Different clouds for different IBM workloads can optimise performance and cost (Watson AI on IBM Cloud, WebSphere on AWS near other services). This introduces licence tracking complexity — use common tools like ILMT to consolidate reports from on-prem and cloud VMs into one unified compliance report.
🔒 Security & Compliance Across Sites
Ensure consistent identity management (integrate IBM Cloud services with corporate AD/SSO). Licence compliance extends across all environments — documentation should show total deployment across Azure + on-prem + AWS doesn't exceed entitlement. Know where everything runs and who is responsible.
🔄 Disaster Recovery & Backup
IBM has rules for cold vs hot backups — cold standby may not require separate licences until activated during failover. Design DR to be compliant and ensure IBM License Service/ILMT captures shifts when failover activates. Testing failovers should include licence compliance validation.
Maintaining Licence Compliance in the Cloud
🔍 IBM License Metric Tool (ILMT)
Essential for VM-based deployments. Free tool from IBM that discovers IBM software installations and measures PVU/VPC usage over time. Required within 90 days of deployment for sub-capacity eligibility. Run on a cloud VM or on-prem server with agents on each IBM software VM. Generates quarterly reports — archive these as audit evidence. Make ILMT part of your cloud deployment pipeline: any IBM product VM created should include ILMT agent automatically.
📦 IBM License Service (Containers)
Essential for Cloud Paks and container deployments. Runs as a container in your cluster, tracking CPU usage of pods running IBM product images. Required within 90 days. Produces reports of peak VPC usage per product. Many Cloud Pak deployments include it by default but configuration is needed (persistent storage, collection jobs). Reports can feed into ILMT for consolidated view. Without it, proving container sub-capacity compliance is impossible.
📋 Regular Internal Audits
Don't wait for IBM's official audit. Conduct internal IBM licence position reviews at least annually — quarterly is better when moving fast in cloud. Establish a centralised asset management database logging deployments (integrated with cloud tagging) mapped to licence IDs. Proactively true-up gaps rather than being caught unprepared.
📄 Documentation & Records
Maintain copies of Passport Advantage entitlements, proofs of purchase, and ILMT/License Service reports for at least 2 years (IBM's typical audit evidence window). Document any special agreements like ELAs or waivers covering cloud use. Create a "cloud licence compliance" runbook outlining how IBM licences are tracked in each environment.
If you discover non-compliance (e.g., an IBM programme ran without ILMT for 6 months, or exceeded VPC counts), take immediate steps. IBM is generally more lenient with self-reporting and remediation than with audit discoveries. Purchase necessary licences, shut down excess use, and document the incident and resolution. Proactive management mitigates audit outcomes significantly.
CIO Recommendations
Develop a Clear IBM Cloud Licensing Strategy
Classify your IBM software portfolio: retain on-prem, rehost to IaaS with BYOL, refactor to Cloud Paks, or replace with SaaS. Map to overall cloud migration plans and business priorities. A roadmap prevents ad-hoc moves that lead to licensing surprises.
Leverage IBM BYOL to Maximise Existing Investments
Before deploying to new cloud environments, check IBM's Eligible Public Cloud list and ensure licence agreements are current. Use BYOL marketplace images for efficiency but maintain internal records of which entitlements are allocated to which deployments. Plan for support renewals to remain entitled to upgrades and IBM assistance.
Evaluate IBM Cloud Paks for Modernisation
Cloud Paks simplify licensing with the VPC model and provide hybrid-cloud flexibility. They often unlock bundled capabilities (AI, automation) that accelerate innovation. Work with IBM on converting existing licences to Cloud Pak equivalents to avoid paying twice — consolidating disparate licences into one bundle often saves costs.
Consider IBM Cloud Satellite for Hybrid Consistency
If your landscape spans on-prem and multiple clouds, Satellite brings IBM Cloud services into your environment securely. Pilot with a non-critical workload to understand integration and cost model. Particularly valuable for data residency requirements where you need cloud-managed services running on-prem.
Implement Rigorous Licence Tracking & Compliance
Deploy ILMT for VMs and IBM License Service for containers immediately. Automate quarterly usage report generation and archiving. Integrate compliance checks into DevOps pipelines — no VM with IBM software deployed without ILMT agent, no container cluster without License Service. Regularly reconcile cloud usage with entitlement.
Compare BYOL vs SaaS on a Case-by-Case Basis
Perform TCO analysis for each major IBM product. Consider intangible benefits like faster feature adoption with SaaS or greater control with BYOL. It might make sense to start BYOL for quick migration and transition to SaaS later, or vice versa. Watch IBM's roadmap — newer AI features may debut on cloud services first.
Foster Close Relationships with IBM & Cloud Providers
Engage your IBM account team when planning major cloud moves — they can clarify licensing nuances and inform you of promotions or policy changes. Work with AWS/Azure/GCP representatives on licence tracking integrations. Cloud providers sometimes have funding programmes or credits for software migrations you can leverage.
Educate & Govern Your Teams
Ensure infrastructure/cloud teams and SAM/licensing teams understand IBM's cloud rules. Conduct workshops on IBM licence management. Update internal policies: "tag all cloud instances running IBM software with 'IBM-licence' for tracking" and "always include IBM License Service container in deployments." Embedding licence awareness into cloud governance reduces non-compliance risk.
Plan for Hybrid Integration & Data Flow
Design secure, efficient communication between on-prem and cloud IBM applications. A poorly connected hybrid environment tempts teams to duplicate workloads (consuming additional licences). Invest in proper networking and integration middleware to run workloads optimally without unnecessary parallel deployments.
Stay Informed on IBM's Cloud Licensing Developments
IBM periodically updates licensing terms, introduces cloud programmes, and changes policies. The PVU-to-VPC shift and BYOL-to-SaaS discount programmes are recent examples. Subscribe to IBM Passport Advantage support bulletins, follow IBM Think announcements, and monitor cloud partnership updates to take advantage of new options quickly.
IBM's cloud services and BYOL offerings allow enterprise customers to run mission-critical software in the environment of their choice. With the right licensing models, governance tools, and strategic planning, the IBM licensing challenge in the cloud can be transformed into a well-tuned practice that supports digital transformation rather than hindering it.
