A reserved instance package is a type of coupon that can automatically match a Pay-As-You-Go instance in your account and offset the bill of the instance. Compared with the Subscription billing mode, the combination of a reserved instance package and a Pay-As-You-Go instance can help you save costs and improve KEC use flexibility.
A reserved instance package allows you to obtain instances that deliver the same performance as Subscription instances at a cost of 40% to 80% lower than Pay-As-You-Go instances.
Discounts of reserved instance packages apply only to the CPU and memory, and not to resources such as the network and storage. Discounts are subject to the instance type, instance configuration, and purchased duration. For more information, see Reserved instance package price information.
