The WebSphere edition structure (Base, ND, Liberty Core, Liberty, Hypervisor Edition, Family Edition, WAS for z/OS). The functional boundary, the contractual boundary, and the typical deployment patterns that cross the boundary.
The PVU and VPC entitlement metrics for WebSphere. The PVU per core ratios on x86, Power, and z. The VPC mapping for Cloud Pak Family Edition. The conversion ratios between the two.
Sub capacity coverage for WebSphere. The ILMT requirement, the scan coverage of the WebSphere binaries, the quarterly Audit Snapshot, the two year retention. The dormant install gap.
Liberty and Liberty Core licensing. The development versus production boundary, the no charge development entitlement, the runtime container packaging, and the deployment patterns.
The Cloud Pak for Applications conversion path. The Family Edition VPC entitlement, the trade up rights, the swap credit, and the OpenShift bundling boundary.
The WebSphere audit posture. The IBM compliance team focus, the evidence requirements, the typical settlement multiplier, the buyer side preparation cadence.
The WebSphere renewal cycle. The S and S optimisation, the harvesting opportunity, the multi year commitment, the discount benchmark, the bundled credit toward Cloud Pak.
The buyer side close position on WebSphere. The five commercial asks, the four contractual asks, the three operational disciplines, the integration to the broader middleware portfolio.
This guide connects to Middleware, Sub Capacity, Cloud Paks, License Consulting, and the broader services portfolio. The work is most powerful when paired with the underlying operational evidence and the renewal cycle timing. See the related papers below and the insights blog for ongoing commentary.
