Capacity Reservations in AWS PCS

You can reserve Amazon EC2 capacity in a specific Availability Zone and for a specific duration using On-Demand Capacity Reservations or Amazon EC2 Capacity Blocks for ML to make sure that you have the necessary compute capacity available when you need it.

On-Demand Capacity Reservations (ODCRs) let you reserve compute capacity for your Amazon EC2 instances in a specific Availability Zone for any duration. You can create and cancel reservations at any time, with no long-term commitments or upfront payments. ODCRs are ideal when you need flexible capacity reservations that you can modify as your requirements change. For more information, see On-Demand Capacity Reservations in the Amazon Elastic Compute Cloud User Guide.

Amazon EC2 Capacity Blocks for ML allow you to reserve GPU-based accelerated computing instances on a future date to support your machine learning (ML) workloads. For more information, see Capacity Blocks for ML in the Amazon Elastic Compute Cloud User Guide.
