This page describes specific networking for public cloud networks that differs from general virtual datacenter networking. For an overview and for a guide to the general features of virtual datacenter networking, see Manage Networks



Synchronize networks

 This feature onboards network elements that were previously created outside Abiquo in public cloud providers. Synchronize networks is available in:

  • AWS: private networks
  • Azure: external networks

Synchronization is available for:

  • Virtual datacenters
    • automatic synchronization of all network elements
  • Private or External networks
  • Public IPs

To import any networks created previously in the cloud provider, click the synchronize element button Image Removed above the Networks list. All networks that were previously created in the cloud provider will be onboarded.

When you onboard virtual datacenters, the synchronize virtual datacenters feature will automatically onboard the networks that belong to the virtual datacenters selected for synchronization.

The network name will be the cloud provider network ID.

Image Removed


When working in Abiquo, DO NOT DELETE networks directly in the provider because this may cause inconsistency. The synchronization process is designed to onboard public cloud elements, especially when you begin to work with a public cloud provider.


Hybrid cloud networking


Azure networks

titleNew feature

For Microsoft documentation about Azure Virtual Networks, see https://azure.microsoft.com/en-us/documentation/articles/virtual-networks-overview/

In Microsoft Azure many different cloud services (virtual datacenters) can have IPs in the same virtual network. Azure manages subnets of these virtual networks and each cloud service can access multiple subnets in a single virtual network. Azure virtual networks are represented in Abiquo as a new network type called a global network. To start with, global networks are only supported in Azure. Abiquo creates a DNS in the Azure account with the global network DNS configuration defined in Abiquo and assigns it to the virtual network. Abiquo removes the DNS configuration when the Azure virtual network is deleted.

This section describes networking in the Abiquo Azure integration.



Create a virtual datacenter with an external network in Azure

When you create a virtual datacenter in an Azure location, you can create a default external network or a custom external network. The Custom private network button changes to a Custom external network button.

Create a custom external network

Abiquo external networks can have private address spaces and be shared across one tenant's virtual datacenters. When the user creates a custom external network in Abiquo, they can select an existing global network, which Abiquo will extend if necessary to include the subnet.

Image Removed

If the user does not select an existing global network, Abiquo will create a new global network. The global network will be of the maximum size, using the subnet address space entered by the user or the default subnet address space.

Image Removed

When Abiquo deploys a machine that does not have an IP assigned, it assigns a private IP in the automatically created default network. In Microsoft Azure, the default network will be an Abiquo external network that is part of a global virtual network.

Create or Edit an Azure External Network

To create new external networks there is a form similar one used when creating a custom network for a new virtual datacenter. As with other virtual datacenter networks, the user can edit a network to change the name and set it as the default network.

Image Removed

AWS networks


During onboarding from public cloud, the platform will onboard existing private networks and public IP addresses (in providers that support them, such as AWS and Azure). 

Add public IP addresses to your virtual datacenter in public cloud

You can obtain public IPs from the provider and assign them to your virtual datacenters and VMs.


Amazon may charge for Elastic IP addresses as soon as you reserve them for your virtual datacenter. Therefore you should reserve your IP addresses just before you deploy and check they are deleted when you undeploy your

virtual machines.


Private networks in AWS

This section describes networking in the Abiquo AWS integration. 

AWS Availability Zones are a high availability feature that enable users to control whether virtual machines will deploy together or separately. When you create custom private networks in the Abiquo virtual datacenter, you can choose which Availability Zone your network will be assigned to. Then you can choose to deploy in a specific Availability Zone by assigning a private IP address in the private network belonging to that Availability Zone.

The following diagram shows a Virtual Private Cloud with the VPC default subnet and the Abiquo default private network.

When you create the VPC, Abiquo creates a private network (VPC subnet) and AWS automatically allocates an Availability Zone.

Network Availability Zones

To find out which Availability Zone a network belongs to, look at the network details box at the bottom of the Networks page. In the screenshot below, the default_private_network is in the "eu-central-1b" Availability Zone.

Choose an Availability Zone when creating a network

When you create a private network, you can select an Availability Zone or select No preference and Abiquo will automatically choose an Availability Zone for you.

Here we have chosen the "-1a" Availability Zone. This is different to the one that the default_private_network is in. And we have named the network to show that it is in Availability Zone "b". In addition, we have selected the Default network checkbox. This means that for virtual machines with no IP addresses allocated by the user, Abiquo will assign IP addresses on this network.

When you click Save, Abiquo will create the network in your AWS VPC. 

Manage public IPs in public cloud

Add floating public IP addresses to your virtual datacenter

Floating public IP addresses are available in many cloud providers, including AWS and Azure.

  • Select a virtual datacenter in your public cloud region
  • Click the add button Image Removed


    To add public IP addresses to your virtual datacenter, so that you can later assign them to your VMs:

    1. Select a virtual datacenter in public cloud and go to Network → Public
    2. Click the add button Image Added in the top right corner of the PUBLIC IPs page


    • Abiquo will check your location (enterprise-public cloud region) limits for public IPs
    1. To add the public IP to a


    1. virtual datacenter, click the Add to VDC link near the IP


    • Abiquo will check your virtual datacenter limits for public IPs
    Synchronize public IP addresses with the cloud provider


    1. address

    Now when you edit a VM in the VDC and go to Network → Public, you will see the public IP address and you can add it to your VM.

    To refresh and onboard any public IP addresses that were already created in your cloud provider, click the Synchronize public IPs button.


    Image Added

    Release a floating public IP address

    To remove the public IP address, first remove it from the virtual machine. Then to remove the public IP address from the VDC, click the Remove from VDC link near the IP address. The IP address will move to the panel on the right. Select the IP address in the list and click the delete button.

    Create a private network

    When you create a virtual datacenter, the platform will automatically create a default or custom private network for the virtual datacenter. 

    To create a private network in your virtual datacenter, click the Image Added button  and complete the form below.

    Edit a private network

    To edit a private network, select the network, then click the Edit button Image Added above the Networks list:

    You can change the network name, gateway, DNS settings, and make the network the new default for this virtual datacenter.

    Changes will apply to all VMs deployed after you click Save.

    Set default virtual datacenter networks

    If you deploy a VM without assigning a NIC, Abiquo will add one in the virtual datacenter's default network.

    To set a new or existing network as the default, when creating or editing the network, select the Default network checkbox. The new default network will apply to all VMs deployed after you set it.  

    Delete a private network

    You can delete a private VLAN if no VMs are using its IPs and it is not the default network. To delete a private VLAN, select it and click the Delete button Image Added above the Networks list.
