Executive Summary

Flexible consumption models promise simplicity—pay for what you use, scale when you need to, and modernise at your own pace. But for IBM i and AIX workloads, the reality behind ‘pay-as-you-go’ models often tells a different story.

IBM’s flexible consumption offerings, along with hyperscaler usage-based pricing, frequently introduce hidden costs tied to idle capacity, complex scaling rules, ecosystem surcharges, and essential services that are treated as add-ons rather than inclusions. The result is unpredictable spending that grows over time.

CloudFirst SmartSpend eliminates these variables by aligning pricing to delivered compute power—not allocated headroom—and including DR, HA, compliance, and security as part of its core model.

The Illusion of Flexibility in Pay-As-You-Go Models

On the surface, IBM’s flexible consumption model and hyperscaler pay-as-you-go platforms appear ideal: scalable resources, usage-based billing, and elasticity on demand. But when applied to IBM i environments, the details reveal hidden drawbacks.

Where do the hidden costs come from?

  • Idle Capacity: Charges are based on provisioned CPW, not delivered compute. Over-allocating capacity to avoid performance issues means paying for unused headroom.
  • Resizing & Scaling Fees: Adjusting CPU or memory often incurs incremental charges. Bursting may require premium rates, and scaling is rarely seamless.
  • Data Egress & Inter-Service Dependencies: Moving data across services or regions adds unplanned fees difficult to forecast in advance.
  • DR, HA, and Security Add-Ons: Essential services for IBM i workloads are rarely included and typically require separate contracts.

The result is simple but expensive: most pay-as-you-go models still charge for unused buffer—not actual performance.

What IT Leaders Want: Predictability Without Sacrifice

For CIOs, CTOs, and CFOs, the core question is clear:

‘Can I reliably predict my monthly spend as workloads fluctuate?’

With traditional consumption models, usage-based billing is only the beginning. Add-on charges, ecosystem dependencies, and variable scaling costs create significant uncertainty. SmartSpend was engineered specifically to remove this instability.

SmartSpend: A Different Approach to Flexible Consumption

SmartSpend ties pricing directly to delivered compute power (CPW)—a measure of real output—while including operational, security, and resilience capabilities typically sold as add-ons.

This model offers:

  • Billing based on delivered CPW, memory, and storage—not idle allocation.
  • No resizing fees, overage penalties, or hidden surcharges.
  • DR, HA, compliance frameworks, and security fully included.
  • Predictable monthly billing with daily consumption tracking.
  • AI-driven workload optimisation to scale environments intelligently.

This structure allows SmartSpend customers to reduce total cost of ownership by 30% or more.

SmartSpend Includes

  • Fully managed IBM i, AIX, and Linux infrastructure
  • Integrated DR and HA
  • Compliance and security hardening
  • Monitoring, patch management, and OS administration
  • Predictive scaling and workload optimisation
  • Backup and restore capabilities

Long-Term Cost Efficiency: A 3–5 Year View

SmartSpend delivers clear financial benefits over a multi-year horizon:

  • Avoid over-provisioning cycles
  • Eliminate charges for resilience and compliance
  • Lower staffing requirements through full management
  • Avoid multi-year vendor lock-in
  • Stabilise OpEx with predictable monthly costs

The result is measurable savings and more reliable planning.

A Partnership Model, Not Just a Pricing Model

SmartSpend is backed by CloudFirst’s collaborative, long-term operating model—not a commoditised service. Organisations gain:

  • Decades of IBM i and AIX expertise
  • Rapid 3–4 week migration timelines
  • A unified cloud for IBM i, Windows, and Linux
  • Fully managed infrastructure with no split responsibility
  • A predictable billing model that eliminates uncertainty

This is not just infrastructure—it is an operational partnership designed to modernise and stabilise IBM Power environments.
