Technology Portfolio Management (TPM) Best Practices

Overview

Cloud and Infrastructure Services occupy a distinct governance position in the Technologies Inventory family because they are consumed services delivered by a third-party provider and governed through a commercial relationship rather than through asset ownership. Their governance obligations reflect this hybrid nature: they share financial governance obligations with software subscriptions, infrastructure governance obligations with hardware assets, and vendor governance obligations with all externally sourced technology assets. They also carry governance obligations unique to the cloud consumption model: the dynamic, consumption-based cost structure that requires FinOps discipline to manage, the geographic data residency implications that cloud provider region selection creates, and the portability and exit risk that vendor lock-in in cloud services produces.

Best Practice

Govern the Cloud and Infrastructure Services Inventory as a comprehensive record of all IaaS, PaaS, and managed services consumed from cloud providers, tagged with the applications and workloads they support. Every cloud service record should capture at minimum: the semantic identifier; the cloud provider and service name; the service type classification; the geographic regions in use; the applications that depend on it; the current cost; the cost attribution tags; the Rationalization Posture and Strategic Disposition; the portability assessment; and the data residency and sovereignty profile.

Cloud service governance is particularly sensitive to three specific risks. Provider concentration risk — the degree to which critical capabilities depend on services from a single cloud provider. Portability risk — the degree to which workloads consuming a specific cloud service could be migrated if needed. Data residency risk — the degree to which cloud service usage creates data sovereignty obligations that the current service configuration may not satisfy. Each should be assessed for every material cloud service dependency and used as an input to both the Strategic Disposition assignment and the vendor negotiation strategy.

Benefit(s)

A well-governed Cloud and Infrastructure Services Inventory provides cloud financial management, compliance governance, and strategic risk management visibility at the portfolio level. Cloud spending is visible and attributable across the full inventory of consumed services. Provider concentration risk is quantified and governable. Data residency compliance is demonstrable to regulators because the inventory records which cloud services process which categories of regulated data in which geographic regions.
