Competitive TCO

A framework for comparing IBM Power total cost of ownership against x86 and cloud alternatives, and what is and is not publicly verifiable in that comparison.

A head-to-head Power-vs-cloud-vs-x86 dollar comparison is one of the most requested numbers in this space, and one of the hardest to publish honestly. IBM Power Virtual Server uses pay-as-you-go pricing for IBM i, AIX, and Linux workloads, but IBM does not publish a simple per-core-hour rate that maps cleanly onto an on-premises comparison, and x86/cloud pricing varies enormously by provider, region, and commitment level.

What actually drives the comparison

IBM i dependencyIf your workload requires IBM i, x86 is not a real substitute -- the comparison narrows to on-prem Power vs. IBM Power Virtual Server.
Utilization patternSteady, predictable load favors owned hardware's amortized economics; spiky or seasonal load favors pay-as-you-go cloud pricing.
Operational controlOn-prem ownership keeps data, firmware, and maintenance timing in your hands; cloud shifts that control (and that overhead) to the provider.
Capital vs. operating costOwned hardware is capital-heavy up front; cloud and subscription models shift the same spend into an operating expense.

What we will not do

We will not publish a fabricated "Power costs $X, cloud costs $Y" headline number when neither IBM's Power Virtual Server pricing nor generic cloud/x86 pricing is published in a form that supports a fair, sourced apples-to-apples comparison. Where a real, citable data point exists -- like IBM's own competitive analysis materials for specific entry configurations -- we will cite it directly rather than approximate it.

Use IBM's own Power Cost Estimator tool and current IBM Power Virtual Server pricing pages for a configuration-specific comparison; those numbers change frequently and are best pulled live rather than cached here.
