Power10 refresh vs. cloud migration
When your Power8 or Power9 fleet ages out, you face one question: buy new Power10 on-prem, or move to cloud Power? Here's how the decision usually breaks.
An on-prem Power10 refresh replaces end-of-support hardware with current Power10 systems you own, full control, but fresh capital and another lifecycle to manage. Migrating to cloud Power (PowerVS, Skytap, or hosted) ends the refresh cycle and shifts to consumption billing, at the cost of ongoing cloud-spend discipline. The right answer depends on your timing, team, and DR strategy.
When each path makes sense
Lean Power10 refresh if…
- You're in a strict data-residency or air-gapped environment
- Latency to other on-prem systems is critical
- You have the team to run Power well
- Capital budget is available and preferred over OpEx
Lean cloud migration if…
- You're consolidating or exiting data centers
- Hardware is at or near end of service now
- Power skills are thin and getting thinner
- You want DR and resilience without a second site
Many teams land on a hybrid: production on cloud Power, or production on-prem with cloud-Power DR. We model both against your numbers rather than defaulting to either.
Frequently asked questions
Should I buy Power10 or move to the cloud?
It comes down to control, capex versus opex, your team's skills, and your DR strategy. On-prem Power10 keeps full control; cloud Power ends the refresh cycle. Many teams land on a hybrid of the two.
Is cloud Power cheaper than buying Power10?
Not automatically. Cloud shifts capital cost to consumption opex; whether it's cheaper depends on utilization and how long you'd hold the hardware. We compare both on a multi-year total cost of ownership.
What happens if I keep running my old Power hardware?
Past end of service, IBM stops hardware maintenance and firmware fixes, spare-parts availability tightens, and a single failure can turn a critical workload into an extended outage.
Can I do both, refresh and move to the cloud?
Yes, and many teams do. A common hybrid is keeping production on-prem with cloud-Power DR, or moving some workloads to cloud Power while refreshing the ones that must stay on-prem.
How the refresh-vs-cloud call gets made
The honest answer depends on your constraints. Two representative decisions.
Situation. Strict data-residency rules and a capable in-house Power team, with hardware near end of service.
Approach. Lean to an on-prem Power10 refresh for control, with cloud Power kept only for DR.
Outcome. Sovereignty preserved and resilience added, without forcing production into someone else's cloud.
Situation. Two data centers being collapsed, thinning Power skills, and a preference for OpEx.
Approach. Move production to cloud Power and retire the on-prem fleet entirely.
Outcome. The refresh cycle ended, a data center closed, and Power operations no longer dependent on hard-to-hire skills.
Representative scenarios reflect common IBM Power migration patterns and typical ranges, not specific named client engagements.
Refresh or migrate: a decision checklist
An end-of-support fleet forces the question. Work through these and you'll know whether new Power10, cloud Power, or a hybrid is your honest answer.
Model refresh vs. cloud on your numbers
We'll run a Power10 refresh and a cloud migration side by side on your actual costs, with no default answer. End-of-life hardware or an expiring maintenance contract shouldn't force the decision.
