Capacity Reservations allocate EC2 capacity in a specific AWS Region for you to launch instances. The capacity is reserved and available to be utilized when needed, meeting the requirement to provide EC2 capacity in the failover region. Other options do not reserve capacity. On-Demand provides flexible capacity but does not reserve capacity upfront. Savings Plans and Reserved Instances provide discounts but do not reserve capacity. Capacity Reservations allow defining instance attributes like instance type, platform, Availability Zone so the reserved capacity matches the production environment.
