Billing Mode

You will be billed on a pay-per-use or yearly/monthly basis.

**Table 1** Billing items
Item	Description	Rule
Configuration fee (mandatory)	Configuration fees are generated when you use computing and storage resources and process data.	In pay-per-use mode, you are charged based on the actual usage on an hourly basis. If the usage duration is less than one hour, you are charged a full hour. In yearly/monthly mode, you need to make upfront payments on a yearly or monthly basis.
EIP fee (optional)	Data processing and data traffic fees generated by public network access. To create a task through a public network, you need to purchase an EIP.	For details, see EIP Billing.

Real-time migration supports only the pay-per-use billing mode.

Real-time synchronization and DR tasks support pay-per-use and yearly/monthly billing modes.
