What are the protection bandwidth quotas of Cloud Firewall in different editions?

Cloud Firewall can protect your Internet traffic and traffic between VPCs. You can increase the protection bandwidth quota based on your requirements. Cloud Firewall in different editions have different protection bandwidth quotas:
  • The default protection bandwidth quota for Internet traffic per month is 10 Mbit/s in Premium Edition, 50 Mbit/s in Enterprise Edition, and 200 Mbit/s in Ultimate Edition.
  • The default protection bandwidth quota for traffic between VPCs per month is 100 Mbit/s in Enterprise Edition and 1 Gbit/s in Ultimate Edition. No protection is provided in Premium Edition.

For more information, see Features and billable items of each edition.

Which types of traffic consume the purchased bandwidth of Cloud Firewall?

Internet traffic consumes the purchased bandwidth of Cloud Firewall. However, the mutual access traffic between virtual private clouds (VPCs) does not consume the bandwidth. For example, if an elastic IP address (EIP) is under a DDoS attack, the traffic to the EIP consumes the purchased bandwidth regardless of whether Cloud Firewall blocks the attack. This is because the traffic is Internet traffic.

What do I do if the volume of my business traffic exceeds the purchased bandwidth of Cloud Firewall?

If the volume of your business traffic exceeds the purchased bandwidth, the excess traffic is not protected by Cloud Firewall. Cloud Firewall can protect only the traffic whose volume does not exceed the bandwidth. To enable Cloud Firewall to protect the excess business traffic, you must increase the bandwidth. For more information about how to increase the bandwidth, see Upgrade Cloud Firewall and change configurations.

If the volume of your business traffic exceeds the purchased bandwidth, we recommend that you perform the following operations:
  • In the Cloud Firewall console, observe the traffic trends displayed on the Overview page and the VPC traffic information displayed on the Traffic Analysis > VPC Access page. Identify suspicious IP addresses based on Cloud Firewall logs and handle the risks.
  • If the volume of your business traffic exceeds the purchased bandwidth, Cloud Firewall sends you a notification email. We recommend that you check your email on a regular basis and handle issues based on the information that is provided in the email.
    Note If the volume of your business traffic exceeds the purchased bandwidth, Cloud Firewall sends you a notification email within 24 hours.
