Use Case Descriptions
Manual Scale Out – This is a first step towards auto-scaling and will be useful beyond the development of auto-scaling. This involves Operations triggering a scaling event through VID. The scaling event will be sent to SO to orchestrate the instantiation of a new VNFC. APPC will then need to finalize the configuration and Healthcheck of the new instance before putting it into service.
Auto Scale Out – This will be a closed loop process that will use telemetry from the VNF to determine if a new instance of a VNFC is needed. If a scaling policy is triggered by the telemetry then a scaling event is sent to the SO for orchestration of the new VNFC. Once the VNFC is built APPC will take over configuration and Healthcheck before placing the new instance into service.
