NCU Limits

NCU Limits help you control costs by setting usage boundaries for application runs with "Included" size configurations. Every Nuvolos subscription comes with a total NCU limit that you can distribute across your resource pools.

Why set NCU Limits? They're an effective tool for managing resource pool or project costs.

What defines an NCU Limit:

• NCU Limit (Capacity): The total NCU hours allocated for your subscription period. Each "Included" size application run mapped to this resource pool draws from this capacity. For example, a 2 CU application running for 3 hours consumes 6 NCU hours.

• NCU Limit Term Start: When your limit becomes active (your contract start or renewal date)

• NCU Limit Term End: When your allocated hours expire (your subscription period end date)

Tracking your consumption

The NCU Capacity tile displays total usage across all application sessions configured with "Included" sizes. The progress bar provides a quick snapshot of consumption since your NCU Limit started.

Want to dig deeper? Resource pool managers can click the Details button at the bottom right to see how usage accumulated over time. This opens the Plan Utilization tab with the date range preset to match your current NCU Limit period.

What happens when you reach your limit

Once you reach your limit or your NCU Limit expires, "Included" size applications can still:

• Start normally

• Continue running without interruption

Everything continues to function as long as you maintain a positive credit balance.

Your options when you exceed your NCU capacity:

1. Purchase more NCU capacity: Contact your Account Manager to add NCU hours to your subscription

2. Use credits: Pay for excess NCU hours with credits. Note that a positive credit balance is required to start new "Included" size applications during overage. Check the prices page for current overage rates.

Quick summary:

• NCU hour consumption applies only to "Included" size configurations

• Consumption depends on your session configuration:

  • Application size (e.g., 4 CU, 16 CU)

  • Add-ons (e.g., Redis, PostgreSQL)

• Once you exhaust your NCU Capacity, credit charges begin automatically

Track credit deductions from NCU overage on the Credit Utilization tab.

Resource pools without NCU limits

Some resource pools don't have NCU limits configured. In these cases, only credit-based size applications can run:
