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 let you reserve GPU-based accelerated computing instances for future use, up to 8 weeks in advance. You can reserve blocks of 1-64 instances for durations from 1 day to 6 months. Capacity Blocks are ideal for machine learning workloads that require guaranteed access to GPU capacity at specific times. For more information, see Capacity Blocks for ML in the Amazon Elastic Compute Cloud User Guide.
