What Are the QPS and Number of New/Concurrent Connections Supported by CFW?

As a SaaS service, CFW is not constrained by the limitations of traditional hardware firewalls, such as the number of new connections, number of concurrent connections, or QPS. Its performance is solely determined by the actual protection bandwidth.

The protection bandwidth is defined as follows:
  • Protected bandwidth: The total bandwidth across all services protected by CFW.
  • Protected bandwidth at the Internet border: The peak inbound or outbound traffic volume across all EIPs protected by CFW.
  • Protected bandwidth at the VPC border: The peak total traffic volume across all VPCs protected by CFW.
