## Service details
The service utilizes kube-ovn VPC and Subnet resources, which use ovn logical routers and logical switches under the hood.
Currently every workload will have a connection to a default management network which will also have a default gateway, and the majority of traffic will be going through it.
VPC subnets are for now an additional dedicated networking spaces.
To function, the service requires kube-ovn and multus CNI to be present, so by default it will only work on `paas-full` bundle.
Kube-ovn provides VPC and Subnet resources and performs isolation and networking maintenance such as DHCP. Under the hood it uses ovn virtual routers and virtual switches.
Multus enables a multi-nic capability, so a pod or a VM could have two or more network interfaces.
A VM or a pod may be connected to multiple secondary Subnets at once.
Each secondary connection will be represented as an additional network interface.
