Scenario 1 - Internal Private Cloud

This example demonstrates the setup of an Internal Private Cloud. A Cloud of this sort cannot be accessed directly from the Internet, if you wish to gain access to the Private Cloud from Internet you should consider our premium Network module or Scenario 2 below. It is also possible to configure the firewall to perform Network Address Translations (NATs) to one or more public IPs and to private IPs in the Cloud Cluster. However, these topics are not within the scope of this document.

In the example below, we have defined three different networks:

• The Management Network connects the Abiquo Server components to the Cloud Cluster. Every single physical machine of the Cloud Cluster should have a dedicated Network Interface Controller (NIC) for this network. Management, monitoring, images deployment traffic will use this network. Size this network to the size of your Cloud Cluster plus your Abiquo servers.

• The Cloud Cluster Network connects the Virtual Images of the Cloud. Every single physical machine of the Cloud Cluster should have at least a dedicated Network Interface Controller (NIC) for this network. Application and Services delivery traffic will use this network. Size this network to the size of the number of Virtual Machines that could handle your Cloud Cluster.

• The Public Network is the one to access the Internet from the Cloud Cluster. In this scenario we have configured the network in such a way that virtual machines can access the Internet. The servers in the Management network can access the Internet too.

This configuration can be a good start for companies, universities, SaaS providers wishing to test the platform instead of a traditional hoster. In order to deploy a complete Cloud Computing platform, contact Abiquo for assistance on what premium modules you would need.

Scenario 2 - Simple Public Cloud

This example demonstrates how to setup a Simple Public Cloud. The Virtual Machines of the Cloud access from Internet directly. To allow access to a Public Cloud from Internet keeping your data secured in a Private Cloud you should consider our premium Network module. The firewall should be configured to allow or deny traffic to the Cloud Cluster, relying on the capabilities of the operating systems running in the virtual images to access or deny the access to the network ports. It's out of the scope of this document to explain how to perform this operation.

In the example below, we have defined two different networks:

• The Management Network connects the Abiquo Server components to the Cloud Cluster. Every single physical machine of the Cloud Cluster should have a dedicated Network Interface Controller (NIC) for this network. Management, monitoring, images deployment traffic will use this network. Size this network to the size of your Cloud Cluster plus your Abiquo servers.

• The Public Network is the one to access the Internet from the Cloud Cluster. In this scenario The Cloud Cluster network becomes the Public Network. We have configured the network in such a way that virtual machines have one or more public IPs assigned. All virtual machines are visible from Internet by default.

This configuration can be a good start for ISPs that want to test the platform as an alternative to Virtual Private Servers (VPS).
