The challenge

Tessera was buying Savings Plans and Reserved Instances reactively — whenever a provider AE suggested it. Their utilization was 67% across the portfolio. Some commitments expired with material unused balance. Others overlapped.

What they did

Tessera implemented monthly portfolio review with three views: coverage, utilization, and attribution. Underused instruments were not renewed. Customer-driven usage was matched to specific commitments under a defined allocation policy. New commitments were sized against trailing 90-day customer usage, not provider recommendations.

"The hardest part was admitting we were treating commitments like a one-off purchase. Once it became portfolio management, the math got obvious."
— CFO, Tessera Group

What happens next

Tessera's discount-portfolio review is now a quarterly board agenda item. They're piloting a customer-facing version of the report as part of their reseller-led FinOps service.
