The Cloud Cluster Network is the orange network in the above diagram. It connects the Virtual Machines in the Cloud. Application and Services delivery traffic will use this network. Hence, Virtual Machines created with Abiquo use this network to communicate with each other. For example, a Java application running on Virtual Machine X can connect to a MySQL server running on Virtual Machine Y on this network.
Abiquo manages this network on different levels:
In the above diagram, the IP range has the format 10.0.0.x. It's possible to configure the initial Class A network and the VLAN tags.
The Cloud Cluster Network can include:
Abiquo recommends at least a 1 Gb NIC per host for this network. Depending on the number of Virtual Machines running on the host, you will need to add more NICs. The size of this network changes according to the number of Virtual Machines that your host can handle. The number of VLANs per Abiquo rack and the number of Virtual Datacenters running in that rack are usually limited by VLAN support in the switch for that rack. Thus it is important to ensure use of VLANs to ensure the efficient use of all computing resources.
In Abiquo 2.3, you can use more than one virtual switch, dvSwitch or network interface card for connecting each hypervisor to the public and external networks. Network cards and VLAN networks are tagged with Network Service Types
