Friction
Cost dashboards show spend, not the architecture decision behind it.
For FinOps and cloud economics
Connect cost decisions to reliability, performance and sustainability — so the cheapest change is not always the one that creates the next incident.
- Unit economics, not just spend
- 4 relevant pillars
- 4 starting points
What gets in the way.
FinOps is most useful when it changes an engineering decision. Wombat puts cost controls next to the reliability, performance and sustainability signals that determine whether a saving is real or just deferred.
Friction
Rightsizing is proposed without a reliability or performance guardrail.
Friction
Commitments and provider discounts hide concentration risk.
Friction
Sustainability targets are disconnected from the workload owner.
What changes with a shared baseline.
The goal is not another dashboard. It is a control model that engineering, security and finance can all use in the same conversation.
- A shared language for cost, performance and reliability trade-offs.
- Controls that make waste and over-provisioning visible at review time.
- A score that shows whether a saving improves or weakens the architecture.
- Evidence for showback, chargeback and supplier negotiations.
Pillars that matter for this role.
Start with the pillars closest to the decisions you own, then use the scorecard to see the whole system.
WAF-COST
Cost Optimization
The dedicated pillar for waste elimination, unit economics and commitment planning.
Read the Cost Optimization pillar →WAF-PERF
Performance Efficiency
Right-sizing only works when utilisation and performance are measured together.
Read the Performance Efficiency pillar →WAF-SUS
Sustainability
Carbon and energy intensity are part of the same efficiency conversation.
Read the Sustainability pillar →WAF-REL
Reliability
A saving that reduces resilience is a future cost, not an optimisation.

Score the workload against cost, performance and reliability, then use the gaps to prioritise the savings that do not create new risk.
