AS400 Hosting vs AS400 Cloud Hosting vs Hosted iSeries
How to compare AS400 hosting, AS400 cloud hosting, hosted iSeries, and PowerVS without losing sight of ownership, backup, security, and migration risk.
Start With The Problem Behind The Hosting Search
A buyer searching for AS400 hosting is rarely just researching terminology. Something is usually forcing the conversation: an aging Power server, a lease ending, a thin IBM i staff, a disaster recovery gap, or a server room that is no longer worth upgrading.
That matters because the right answer changes by trigger. A shop trying to exit a data center needs a different provider conversation than a shop trying to add standby capacity or buy a year of runway before a hardware refresh.
Separate Capacity From Management
Hosted capacity and managed operations are not the same thing. A provider may supply Power infrastructure while the buyer still owns IBM i administration, patching, backup policy, and application support. Another provider may bundle LPAR management, monitoring, backup testing, security reporting, and after-hours response.
Buyers should ask what is included before comparing monthly prices. The cheapest quote often excludes the work that made hosting attractive in the first place.
- Who manages the LPAR and HMC layer?
- Who owns IBM i patching, PTF planning, and release upgrades?
- Who proves backups restore successfully?
- Who receives alerts after hours and what authority do they have?
Compare Hosted iSeries, AS400 Cloud Hosting, And PowerVS
Hosted iSeries usually means a provider-managed environment built for IBM i workloads. AS400 cloud hosting may mean the same thing, or it may refer to Power infrastructure placed near cloud services for hybrid integration. PowerVS is IBM Power Virtual Server in IBM Cloud, which gives buyers Power infrastructure for IBM i, AIX, and Linux workloads without changing processor architecture.
Those paths can all be valid, but they solve different ownership problems. A mature buyer asks less about the label and more about where the workload runs, who operates it, how recovery is tested, and how the network path reaches users and integrations.
Treat Migration As A Project, Not A Switch
Moving an AS/400 or IBM i workload into a hosted environment still requires planning. Data replication, user access, printer and EDI dependencies, batch windows, licensing, and rollback all need attention before the cutover window.
A useful hosting proposal should include migration steps, expected downtime, validation responsibility, and fallback plan. If those details are missing, the quote is capacity pricing, not a hosting solution.
Frequently Asked Questions
Is AS400 hosting the same as AS400 cloud hosting?
Not always. AS400 hosting usually means a provider runs IBM i or iSeries infrastructure for the buyer. AS400 cloud hosting may mean hosted Power capacity, PowerVS, or a managed environment connected to cloud services. The safer buying question is who owns operations, backup, security, and recovery, not which label the vendor uses.
What makes an AS400 hosting lead high intent?
Hosting searches often happen when a buyer has an aging server, a staffing gap, a support deadline, or a data center exit requirement. Those are commercial problems tied to budget, risk, and timing, which is why the query intent usually converts better than broad educational AS400 searches.
