2.6 Autoscaling and Bursting a vApp
Several ways to control autoscaling and bursting of a vApp are described in this section. All require the upscale and downscale workflows to be triggered from a monitoring system:
Pull
– vCenter Orchestrator checks
an external monitoring system to determine whether upscaling or downscaling is required.
Push
– The monitoring system
can provide enough information to Orchestrator or to an
application that then talks to Orchestrator. vCenter Orchestrator
can use any of the following mechanisms to start a workflow:
The SOAP web service
– to start the workflows directly.
The REST web service
– to start the workflows directly.
The AMQP plug-in
– to trigger a workflow when consuming a message that has been published on an AMQP message bus.
The SNMP plug-in
– to trigger a workflow when receiving an SNMP trap.
