This page introduces Abiquo networking concepts in terms of the platform networks that the system administrator must configure in the infrastructure and the cloud networks within the Abiquo platform


This page describes the platform networks that the system administrator configures in the infrastructure and the cloud networks created within the Abiquo platform.

Platform networks

Excerpt

The main platform networks to configure separately for the platform datacenters are:

  • Management Network: used by the Abiquo platform components to manage the virtual resources. It connects the Abiquo Server and Abiquo Remote Services to the hypervisors that they manage. The platform also monitors infrastructure and VMs on this network. And it also deploys VM templates over this network.

  • Service Network:  contains the virtual networks (VLANs) for the cloud
  • Storage Network: optionally used to connect the hypervisors to external storage devices with user volumes and persistent VM disks
  • Public Network: used to connect VMs to the Internet. This network can include multiple public VLANs and different subnets of routable Internet addresses.

These networks are shown in the following network topology diagram

Cloud network configuration

In private cloud, you can use standard networking or software defined networking (SDN). In public cloud and cloud providers, Abiquo supports provider networking options.

Private cloud networks

In private cloud with standard networking, cloud networks are VLANs in the 'service network' that runs on the Abiquo platform networks. 

For each datacenter, the network administrator should design the configuration (e.g. VLAN tags, switches, SDN) that will be required.

For standard networks, the administrator must configure the cloud platform switches to support the VLANs that make up the service network.  

When using standard networking you can configure VM IP addresses using DHCP or guest setup. The default configuration is the DHCP server installed by Abiquo but you can also provide your own DHCP server. If a DHCP server is not found, Abiquo uses guest setup with cloud-init and hypervisor tools, requiring compatible templates, or a custom guest setup method.

Public cloud

Abiquo supports many different public cloud providers with different types of networking. For example, in AWS, Abiquo onboards VPCs, and creates VPCs with NAT support, and Abiquo manages Elastic IPs. In Google Cloud Platform, Abiquo supports Global (VPC) networks, and subnets.

See the Public cloud integrations and Public cloud providers documentation for more information about specific providers.
