# Low Capacity Instances (GPUs) ## On AWS There are multiple types of commitments that AWS offers, some of which — like Zonal Standard Reserved Instances (RIs) — come bundled with a capacity reservation to ensure access to the underlying machine being covered. See [AWS capacity reservations documentation](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-capacity-reservations.html) for more details. By default, Archera Guaranteed Commitments are created from Regional Standard RIs or Savings Plans, which don't come with a capacity reservation; however, they can synergize with an existing capacity reservation to provide a billing discount. In certain circumstances — particularly with machines like GPUs that have low-capacity-availability — Archera supports creating Guaranteed RIs (GRIs) from **Zonal Standard RIs**, which do come with a capacity reservation and can give customers the peace of mind that they will always have access to spin up the machine they are committed to. Please note that this is **not the default GRI option** and you will have to contact us in order to make use of this option. If you are interested in using Zonal GRIs with a capacity reservation, please contact to learn more. ## Related Resources * [How Does Guaranteed Commitment Pricing Work?](/help-center/guaranteed-commitments/pricing.md) * [What are Guaranteed Commitments?](/help-center/guaranteed-commitments/what-are-guaranteed-commitments.md) * [Does Archera support On Capacity Demand Reservations?
