Abiquo 4.0 introduces horizontal autoscaling of virtual machines through scaling groups created for virtual machines. When a scaling event is triggered, Abiquo will follow the scaling rules of the scaling group. To scale out, it will clone the base virtual machine (with the template disk content) and deploy, and to scale in, it will delete clones or undeploy the base virtual machine.

To use autoscaling do these steps:

1. Create a base virtual machine
2. Define a scaling group for a base virtual machine, including scaling rules
3. Create an action plan for the virtual machine with scaling actions
4. Create scaling triggers, which are either monitoring alerts for virtual appliances or schedules for planned scaling
