Amazon EC2 Fleet simplifies the provisioning of EC2 capacity across different instance types, Availability Zones (AZs), and purchase options to optimize for scale, performance, and cost. Allocation strategies let you determine how EC2 Fleet should select from the instance types and AZs you have specified to fulfill the desired capacity. The new Capacity Reservation usage strategy works in conjunction with the Allocation Strategy (lowest-price or prioritized). This feature is ideal for secondary workloads that can utilize reserved capacity held for primary workloads during off-peak hours, there by minimizing your overall compute costs.
