Network types
Cloud Networks service allows to work with several network types.
Standard network provides access to the subnets with the private IP addresses and exists within a single project.
The standard network, its subnets and ports can be managed via personal account, OpenStack CLI or Terraform.
Shared network provides access to the subnets with the private IP addresses too, but exists across several projects. Users, who have a cloud infrastructure that is distributed between several projects, can request an access to this network type.
Firstly, a standard network should be created in the owner project. Then this network can be converted to the shared network via the support request. The shared network then will be accessible from the one or several dependent projects.
A shared network, its subnets and ports can be managed via personal account, OpenStack CLI or Terraform from the owner project. A shared network can be deleted only via the support request.
It is possible to view the information about a shared network via personal account from a dependent project, but it is allowed only to manage ports of the network via OpenStack CLI. Also, it is not possible to connect DB instances or Kubernetes cluster to a shared network from a dependent project.
External network (ext-net, internet) provides access to the subnets with the public IP addresses and exists across all projects. It is used to provide services with the Internet access. See details in the Network addressing and internet access section.
It is not possible to edit or delete the subnets of that network. The following operations can be performed via personal account, OpenStack CLI or Terraform:
- Assigning the network to a virtual machine.
- Assigning the network for a router external network connection.
