Abiquo components are modular and it is possible to install them on multiple servers. Abiquo has the following main installation profiles:
Monolithic with all the components on a single appliance, for test environments.
Distributed scalable with each component on its own appliance
Distributed HA cluster with multiple load balanced API/UI nodes, datanodes, and monitoring nodes.
...
For proof of concept and other testing, you can use a Monolithic environment that has all of the Abiquo components on the same appliance. A test environment can also include a monitoring appliance as in a production installation.
...
In production installations, the components are configured as Distributed environments. This means that each server has separate Abiquo components for improved performance and reliability.
...
For high availability, in an HA cluster environment you will usually configure clusters for the API and UI nodes, the Datanodes, and the Monitoring nodes, for example, with 3 servers each, and with load balancing and floating IPs.
