# VPC
|
|
|
|
VPC offers a subset of dedicated subnets with networking services related to it.
|
|
As the service evolves, it will provide more ways to isolate your workloads.
|
|
|
|
## Service details
|
|
|
|
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.
|
|
|
|
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 go through it.
|
|
VPC subnets are for now an additional dedicated networking spaces.
|
|
|
|
## Deployment notes
|
|
|
|
VPC name must be unique within a tenant.
|
|
Subnet name and ip address range must be unique within a VPC.
|
|
Subnet ip address space must not overlap with the default management network ip address range, subsets of 172.16.0.0/12 are recommended.
|
|
Currently there are no fail-safe checks, however they are planned for the future.
|
|
|
|
Different VPCs may have subnets with overlapping ip address ranges.
|
|
|
|
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.
|
|
|
