Reserved instance (RI) is a billing discount applied to the use of pay-as-you-go CVM instances under your account. These CVM instances must exactly match attributes of the RI you purchased to benefit from the billing discount during the RI term. RI provide you with a significant discount compared to pay-as-you-go billing.
RI is currently in beta. Prices published here are for reference only. Refer to your bills for final prices. Contact sales if you need further help.
Currently, RIs are non-refundable.
Configurations of an RI cannot be changed after purchase. The RI billing discount will no longer apply to the matched instance if you change its configurations.
The RI billing discount will still apply to matched CVM instances even after they are proactively or forcibly shut down.
Currently, RIs are only offered to beta users. To use it, submit an application to be an RI beta user.
The pay-as-you-go CVM instances must exactly match RI attributes to benefit from the billing discount during the RI term.
