Pay-per-use billing and packages are available for new-version ROMA Connect instances.

Pay-per-use: The instance is billed based on the RCU quantity and duration (by hour). If the duration is less than an hour, billing is based on the actual usage.
Packages: A package contains a specified RCU-hour quota. A ROMA Connect instance of the new version consumes the RCU-hours in the package first, and the overflow (if any) is billed on a pay-per-use basis. The package quota is valid only in one effective month. The remaining quota expires and cannot be transferred to the next month.
If you select 1,000 RCU Hours/Month for a five-RCU instance, you can use the instance for 200 hours in the effective month. After the 200 hours, the instance is billed in the pay-per-use mode. If there are multiple instances, the total number of RCUs will be calculated.
