Pay-Per-Use

Preferential Policies

We have arranged preferential pricing in the following scenarios:

Real-time migration tasks are free of configuration and traffic fees in the first seven days, lowering your costs for migrating data to the cloud.
Real-time migration and synchronization tasks will provide long-term discounts, lowering your costs for data transfers.

Billing Standards

DRS supports the pay-per-use billing mode. You are charged for the configuration and data transfer of each instance.

**Table 1** Pay-per-use pricing details
Item	Description
Configuration fee	Configuration fees are generated when you use computing and storage resources and process data. You are charged for a full hour regardless of whether you use the full or partial hour.
Data transfer fee	Data transfer fees are generated when you process or transfer data through a public network (excluding VPN, VPC, Direct Connect, and CC networks). No matter what billing mode is used, DRS charges you for the actual public network traffic you use in GB.

For details about the DRS configuration fee, see Product Pricing Details. You can use the price calculator provided by DRS to quickly calculate the reference price based on the required specifications.

Billing Example

Figure 1 Billing example

The following uses full plus incremental migration of a MySQL database in region CN Hong Kong as an example to describe DRS pricing:

Scenario 1: Migrating data to the cloud within the free-of-charge period
If you started the migration to the cloud at 8:00 on July 1, 2021 and ended the task at 12:00 on July 3, 2021, the service duration is less than one week so you will not be charged.
Scenario 2: Migrating data to the cloud beyond the free-of-charge period
If you started the migration to the cloud at 8:00 on July 1, 2021 and ended the task at 12:00 on July 16, 2021, the service duration exceeds the free-of-charge period that ends at 8:00 on July 8, 2021. From 08:00 on July 8, 2021 to the end of the task, you will be charged $0.35 USD per hour for the configuration and $0.21 USD/GB for data transfer.

Scenario 3: Migrating data out of the cloud
If you started migrating 100 GB of data out of the cloud at 8:00 on July 1, 2021 and ended the migration task at 8:00 on July 3, 2021 over a public network, you will be charged for configuration and data transfer. The configuration fee is calculated as follows: 2 days x 24 hours x $0.35 USD/hour = $16.8 USD. The data transfer fee is $21 USD (100 GB x $0.21 USD/GB). The total amount is $37.8 USD (16.8+21).

Scenario 4: Starting multiple migration tasks
Task 1: You started migrating 100 GB of data to the cloud at 08:00 on July 1, 2021 and ended the task at 12:00 on July 9, 2021. Task 2: You started migrating 200 GB of data out of the cloud at 8:00 on July 1, 2021 and ended the migration task at 8:00 on July 6, 2021 over a public network.
- The free-of-charge period ended at 8:00 on July 7, 2021. For task 1, you will be charged configuration fees of $0.35 USD per hour from 8:00 on July 7, 2021 to the end of the task. Any data transfer coming from the Internet into our cloud is free. Task 1 fees = Configuration fee + Data transfer fee = (2 days x 24 hours + 4 hours) x $0.35 USD/hour = $18.2 USD.
- Task 2 charges configuration fees of $0.35 USD per hour. The data transfer fee is charged at $0.21 USD. Task 2 fees = Configuration fee + Data transfer fee = 5 days x 24 hours x $0.35 USD/hour + 200 GB x $0.21 USD/GB = $84 USD.
Scenario 5: Migrating data over non-public networks
If you started migrating 100 GB of data to the cloud at 08:00 on July 1, 2021 and ended the task at 08:00 on July 3, 2021 through a VPC network, you will not be charged because the service duration is within one week and data transfer in a private network is free.
