AI, Data & SaaS Spend

Cost Allocation

The process of attributing every unit of cloud, data and SaaS spend to the team, product, feature or customer responsible for it.

Cost Anomaly Detection

Automatically identifying unexpected changes in spend against a learned baseline pattern.
Read definition
Unit Economics

Cost Avoidance

Spend that was prevented rather than removed cost that would have been incurred without an intervention.
Read definition
Allocation & Accountability

Cost Centre

A defined unit of the business — team, product, department or project that owns a budget and is accountable for the spend attributed to it.
Read definition
Unit Economics

Cost per Customer

The fully allocated infrastructure cost of serving one customer or tenant over a period.
Read definition
AI, Data & SaaS Spend

Cost per Token

The price charged per unit of text processed by a language model, usually quoted separately for input and output.
Read definition
Unit Economics

Cost per Transaction

Infrastructure cost divided by the number of business transactions processed in the same period.
Read definition
Commitments & Rates

Coverage

The share of eligible usage that is covered by a commitment rather than billed at on-demand rates.
Read definition
AI, Data & SaaS Spend

Data Transfer Costs

Charges for moving data out of, between or across regions and availability zones of a cloud provider.
Read definition
Commitments & Rates

Effective Savings Rate

Total discount achieved across all spend, measured against what the same usage would have cost at on-demand rates.
Read definition
Practice & Governance

FinOps

An operating model that brings engineering, finance and business teams together to manage variable cloud spend collaboratively.
Read definition
Practice & Governance

FinOps KPIs & Benchmarking

The metrics used to measure a FinOps practice: allocation rate, ESR, coverage, utilisation, waste and unit cost trend.
Read definition
Practice & Governance

FOCUS

An open standard schema for billing data, designed to make cost reporting consistent across providers.
Read definition
AI, Data & SaaS Spend

GPU Cost Optimisation

Managing the cost of accelerator capacity used for training, fine tuning and inference.
Read definition
Kubernetes & Containers

Idle Resources

Provisioned resources that are running and billed but doing little or no useful work.
Read definition
Kubernetes & Containers

Kubernetes Cost Allocation

Attributing the cost of a shared cluster to the namespaces, workloads, teams and products running inside it.
Read definition
Kubernetes & Containers

Kubernetes Idle Cost

The cost of cluster capacity that is provisioned and paid for but not consumed by any running workload.
Read definition
Allocation & Accountability

MegaBill

A single unified bill that normalises every cloud, data platform and SaaS cost source into one consistent, queryable cost model.
Read definition
Practice & Governance

Multi-Cloud Cost Management

Managing and comparing spend across two or more cloud providers under a single cost model.
Read definition
Kubernetes & Containers

Namespace Cost

Cluster cost aggregated to the Kubernetes namespace, often the simplest proxy for team ownership.
Read definition
Commitments & Rates

Net Amortised Cost

Amortised cost after applying all discounts, credits and private pricing — the closest figure to true economic cost.
Read definition
AI, Data & SaaS Spend

Observability Cost

Spend on logs, metrics, traces and APM — frequently one of the largest non-compute line items.
Read definition

Platform capabilities consumed by many teams — CI/CD, observability, networking, shared clusters and databases.
Read definition
Allocation & Accountability

Showback

Reporting cloud costs back to the teams that caused them, for visibility and accountability, without transferring budget.
