Secure short-term GPU capacity for ML workloads with EC2 Capacity Blocks for ML and SageMaker training plans
AWS just made GPU capacity less of a poker game. EC2 Capacity Blocks let you lock in short-term GPU access without the usual scarcity tax.
Why it matters
AWS is addressing a real pain point for ML teams: GPU scarcity and unpredictable pricing. By enabling reservation of short-term capacity blocks and SageMaker training plans, they're reducing friction in model validation and load testing workflows—directly lowering friction for enterprises scaling ML workloads.
