Max. Protection Traffic Between VPCs |
Professional edition |
If the basic protection bandwidth (200 Mbit/s) cannot meet your requirements, you can purchase extra protected VPCs to increase the bandwidth. |
No charging. Max. Protection Traffic Between VPCs = (Number of VPCs – 1) × 200 Mbit/s |
Billing Examples
Suppose you purchased a one-month CFW subscription on June 30, 2023, 15:50:04 (edition: professional; extended package: one added EIP, 5Mbit/s peak protection traffic, and one added VPC). Billing resources include the professional edition and extended package (added EIPs, added peak traffic protection capacity, and added VPCs). Your subscription is one month and you manually renew the subscription for another month before the subscription expires. The billing details are as follows:
· The first billing period is from 15:50:04 on June 30, 2023 to 23:59:59 on July 30, 2023.
· The second billing period is from 23:59:59 on July 30, 2023 to 23:59:59 on Aug. 30, 2023.
Modifying Configurations
Changing CFW Specifications
The CFW standard edition can be upgraded to the professional edition, but the professional edition cannot be changed to the standard edition. To change to a lower edition, unsubscribe from the current edition and purchase the required one.
To change the engine of your edition, unsubscribe from the edition and purchase the required one.
Constraints
CFW can be used in the selected region only. To use CFW in another region, switch to the corresponding region and then purchase it. For details about the regions where CFW is available, see Can CFW Be Used Across Clouds or Regions?
Price Change After Specification Change
If the specifications of yearly/monthly CFW resources no longer meet your needs, you can change the specifications on the console. The system will recalculate the price and either bill or refund you the difference.
• If you upgrade your CFW specifications, you need to pay the difference in price.
Suppose there is no discount for resource upgrade and you purchased a one-month standard edition CFW with one EIP and 5 Mbit/s peak traffic on June 8, 2023, and added one VPC on June 18, 2023. The price of the original specifications was $462 USD/month, and that for the new specifications was $1,792 USD/month. The price difference will be calculated as follows:
Specification upgrade fee = New specification price × Remaining period - Old specification price × Remaining period
The remaining period is the remaining days of each calendar month divided by the maximum number of days in each calendar month. In this example, Remaining period = 12 (Remaining days in June)/30 (Maximum number of days in June) + 8 (Remaining days in July)/31 (Maximum number of days in July) = 0.6581. Cost of upgrade = 1792 x 0.6581 - 462 x 0.6581 = $875.273 USD

Renewing Subscriptions
If a yearly/monthly CFW instance is about to expire but you want to continue using it, you need to renew the CFW subscription within a specified period, or resources, such as protection rules and logs, will be automatically released, and data will be lost and cannot be restored. If you renew the CFW instance before it expires, resources will be retained and you can continue using the instance.
Expiration
If your yearly/monthly CFW instance expires and is not renewed, after it expires, it changes to the Expired state and enters a grace period. During the grace period, you can access CFW.
If you do not renew your yearly/monthly CFW instance before the grace period ends, it goes into the retention period and its status turns to Frozen. You cannot perform any operations on such instances in the retention period.
If the yearly/monthly CFW resources are not renewed by the time the retention period ends, the CFW instance and protection configurations will be released and data cannot be restored.
Billing Mode
Yearly/Monthly
A yearly/monthly CFW instance is billed for the purchased duration. The billing starts when you activated or renewed the subscription (accurate to seconds), and ends at 23:59:59 of the expiry date.
For example, if you purchased a one-month CFW instance on June 30, 2023, 15:50:04, the billed usage period is from June 30, 2023, 15:50:04 to July 30, 2023, 23:59:59.
Application Scenarios
If you expect to use resources for a longer period, you can save money by selecting yearly/monthly billing. You can pre-purchase CFW resources at discounted prices. If you want to ensure resource stability over a certain period of time, yearly/monthly billing is a good choice for the following types of workloads:
• Long-term workloads with stable resource requirements
• For long-term projects
• Workloads with predictable traffic bursts
• Workloads with high data security requirements
