Hi, dear!


Can anyone tell me what is vFW in Huawei Cloud?


I am preparing for the HCIP exam of Cloud Computing. 

One question introduces that which of the access rules of cloud services that can be used to manage cloud services., and the answer is vFW, but I have no idea about it. What is it?


Thank you in advance!

Hello, friend!

vFW is short for virtual firewall.

Region Type I: A firewall consists of one or more access control lists (ACLs). Based on inbound and outbound network ACLs, the firewall determines whether data packets are allowed in or out of any associated subnet. The firewall and security group work at different levels. The firewall is used to protect the traffic reaching and leaving a subnet. The security group, which governs the cloud server port, is used to perform access control on the traffic of a specified cloud server.

Region Type II: A firewall consists of one or more access control lists (ACLs). Based on inbound and outbound network ACLs, the firewall determines whether data packets are allowed in or out of any associated VPC. The firewall and security group work at different levels. The firewall is used to protect the traffic reaching and leaving a VPC. The security group, which governs the cloud server port, is used to perform access control on the traffic of a specified cloud server.

Hope this helps!
