How Priority achieved a steady 99% Savings Plans coverage with automation
Customer Brief
Priority Software is a global enterprise software company founded 40 years ago. Best known for its leading ERP platform, it has recently expanded into business management solutions for retail, education, and hospitality. The company serves 15,000+ customers worldwide and continues to scale across regions and product lines. To support this growth, they operate a robust AWS infrastructure built around containerized workloads and EKS.
Priority runs a large, multi-tenant AWS environment, and the biggest challenge was keeping Savings Plan coverage constantly high as workloads and infrastructure constantly changed.
Zesty’s Commitment Manager helped Priority raise Savings Plan coverage from 85% to a steady 99%, eliminate coverage drift, and cut commitment ops to a few minutes, while preserving flexibility over time.
The Challenge
Priority Software runs a large, multi-tenant AWS platform supporting thousands of customers across multiple product lines. The environment spans four AWS regions and multiple accounts, segmented by line of business and budgets. Most workloads are containerized and run on Amazon EKS across multiple Kubernetes clusters, each with a significant number of nodes.
The team relied exclusively on Savings Plans to keep commitments flexible. They were managed through an external partner in a semi-manual process, usually adjusted only once a month.

Zesty’s Solution
When Priority met Zesty, it was clear that Commitment Manager could improve the Savings Plan coverage with automation.
The onboarding was straightforward and only required connecting accounts, but the bigger part was the transition away from partner-managed commitments. Priority needed a gradual migration plan to safely release existing commitments and ramp up new ones without disrupting coverage.

The Zesty team worked through the strategy with Priority, managed the rollout step by step, and coordinated with the previous partner.
They helped with practical decisions around term mix and flexibility, handling the calculations and details behind the strategy, like balancing 1-year and 3-year terms and accounting for weekday/weekend workload shifts.
Commitment Manager gradually replaced the current commitments with micro Savings Plans. Once coverage reached the target, it continued to automatically adjust commitments on a daily basis, buying, renewing, or letting Savings Plans expire as needed.

The Result
With Zesty’s Commitment Manager in place, Priority moved to continuous, automated coverage optimization.
Savings Plans coverage increased from roughly 85% to 99%, improving savings across thousands of workloads in a way that couldn’t be done manually.
Instead of depending on periodic updates and declining over time, coverage stays consistently high, with Commitment Manager running in the background as workloads grow and shift across accounts, regions, and product lines.
Savings Plan management no longer requires coordination or constant follow-ups, just short checks to confirm coverage remains high.

As Priority continues to grow, Commitment Manager preserves flexibility over time. It’s reassuring for the team to know that if usage ever changes in the future, micro commitments make it easier to adapt.
Looking ahead, the Priority team would like to extend Commitment Manager beyond compute to the database footprint, especially RDS, which is not covered today.
