IBM published a case describing how an internal IBM Cloud VPC team migrated its CI infrastructure, citing scale items such as a large number of CI pipelines and artifacts to build, scan, and test, and a move from many virtual server instances to Kubernetes clusters hosting Tekton private workers.
Critical evaluation:
- This is vendor-published material about an internal team; it demonstrates that IBM used the platform at scale for internal needs but does not provide independently audited metrics on cost reduction, reliability improvements, or developer productivity.
- Procurement teams should request before-and-after cycle time metrics, failure rate and MTTR changes, detailed cost models (cluster costs, pipeline usage, staffing), and any unique assumptions applicable to IBM’s internal environment.
