The Hidden Cost of Under-Committed Cloud

For most organisations with material cloud spend, reserved instances and savings plans represent the largest single lever for reducing cloud cost — often delivering 30–60% savings on eligible compute spend compared to on-demand pricing. Despite this, many organisations consistently under-utilise their commitment capacity: they hold reservations for workloads that have been decommissioned, fail to apply savings plans to eligible compute categories, and continue paying on-demand pricing for workloads that run predictably enough to justify commitment.

Haylix ASSESS gives finance and FinOps teams a structured view of their commitment coverage and a prioritised plan to close the gap.

What the Commitment Optimisation Assessment Covers

The Cost Optimisation assessment includes a dedicated commitment analysis that evaluates:

• Reservation utilisation — what percentage of existing reserved instances are being actively consumed, and which reservations are being wasted on decommissioned or changed workloads?
• Savings plan coverage — what percentage of eligible compute spend is covered by compute savings plans, EC2 savings plans, or equivalent commitment instruments?
• On-demand overspend — which workloads are running predictably on on-demand pricing where commitment pricing would deliver material savings?
• Commitment expiry management — which reservations and savings plans are approaching expiry, and do renewal decisions need to be made?
• Commitment type optimisation — are the most flexible commitment instruments being used for variable workloads, and the most discount-efficient instruments used for stable workloads?
• Cross-account and cross-region sharing — is reserved capacity being shared appropriately across the organisation’s account structure?

Commitment Optimisation Outputs for Finance Teams

Haylix ASSESS produces a Commitment Optimisation Report that supports FinOps decision-making:

1. A commitment coverage dashboard — showing current coverage rates against eligible spend, by compute category and account
2. A waste register — identifying reservations that are not being utilised, with monthly cost and recommended actions (sell on marketplace, modify, or convert)
3. A commitment opportunity register — specific workloads where committing would deliver measurable savings, with estimated savings values and commitment instrument recommendations
4. An expiry calendar — a timeline of upcoming commitment renewals with recommended actions for each

Building a Commitment Management Discipline

Ad-hoc commitment management — purchasing reservations when a cost reduction is needed and forgetting about them until the next budget cycle — leaves significant savings on the table. FinOps teams who use Haylix ASSESS build a structured commitment management cycle:

1. Quarterly coverage review — assess commitment coverage rates and identify coverage gaps for workloads that have stabilised since the last review
2. Waste remediation — identify and action underutilised reservations, selling convertible reservations on the marketplace or modifying them to match current workload sizes
3. Renewal management — review upcoming commitment expirations and make renewal decisions based on current workload trajectory rather than automatic renewal
4. New commitment purchases — use the commitment opportunity register to identify and prioritise new purchases, supported by workload utilisation analysis from the assessment

The Commitment Optimisation Business Case

For finance teams operating in organisations with material cloud spend, the savings available from commitment optimisation are often significantly larger than the savings from waste elimination. A workload spending $50,000 per month on on-demand compute that could be 60% covered by savings plans represents $360,000 in annualised savings from a single commitment decision.

Haylix ASSESS provides the evidence and analysis needed to make these commitment decisions with confidence, and the tracking capability to demonstrate to leadership and the board that FinOps commitment management is delivering quantifiable financial value.
