To provide a highly flexible and secure network infrastructure in a multipurpose cloud environment, Cyfuture Cloud Console uses a layered networking architecture with four categories of networks. The network categories are external networks, organization virtual data center (VDC) networks, data center group networks, and vApp networks. Most types of Cyfuture Cloud Console networks require additional infrastructure objects, such as edge gateways and network pools.
External Networks
An external network provides an uplink interface that connects networks and virtual machines in your Cyfuture Cloud Console environment to outside networks, such as a VPN, a corporate intranet, or the public Internet.
An external network is backed either by a single VMware vSphere network, by multiple VMware vSphere networks, or by an Advanced Networking Data Center tier-0 logical router.
Only a system administrator can create an external network. For information about external networks, see Cyfuture Cloud Console Service Provider Admin Portal Guide.
Network Pools
A network pool is a collection of isolated layer-2 network segments that you can use to create vApp networks and certain types of organization VDC networks on demand.
Network pools must be created before organization VDC networks and vApp networks. If they do not exist, the only network option available to an organization is the direct connection to an external network.
Only a system administrator can create a network pool.
For information about network pools, see Cyfuture Cloud Console Service Provider Admin Portal Guide.
Organization VDC Networks
Organization virtual data center (VDC) networks enable vApps to communicate with each other or with external networks outside the organization.
Depending on the connection of the organization VDC network to an external network, there are several different types of organization VDC networks.
Organization VDC networks provide direct or routed connections to external networks, or can be isolated from external networks and other organization VDC networks. Routed connections require an edge gateway and a network pool in the organization VDC.
A system administrator or an organization administrator creates organization VDC networks and assigns them to your organization.
A newly created organization VDC has no networks available to it. After a system administrator creates the required network infrastructure, an organization administrator can create and manage most types of organization VDC networks.
Data Center Group Networks Backed by Networking Data Center for VMware vSphere
A network backed by Networking Data Center for VMware vSphere that spans a data center group. A data center group can comprise between one and 16 organization VDCs in a single or a multisite Cyfuture Cloud Console deployment.
Data Center Group Networks Backed by Advanced Networking Data Center
Data center group networks are a type of organization VDC networks that are shared between one or more VDCs and to which vApps can connect.
A system administrator or an organization administrator creates data center group networks and scopes them to a single VDC group.
Cyfuture Cloud Console supports isolated, imported, direct, and routed data center group networks that are backed by Advanced Networking Data Center.
vApp Networks
vApp networks allow virtual machines to communicate with each other or, by connecting to an organization VDC network, with virtual machines in other vApps.
A vApp network is contained within a vApp. A vApp network can be isolated from other networks or connected to an organization VDC network.
Every vApp contains a vApp network. The network is created when the vApp is deployed, and deleted when the vApp is undeployed.
An organization administrator sets up and controls vApp networks.
