With the increase of rapid deployment and management of new network services within CoSPs network, the dynamic scale-in/out controls are playing a crucial role to maintain the resiliency of critical services with optimal level of performance and resource utilization while responding to the changing packet processing demand in a live network. Furthermore the 5G Network Slicing, Edge Cloud and Cloud Native use cases put an immense pressure on CoSPs network to efficiently manage the production services. In the past, the SW based controls have been introduced in VIM managers with the dynamic discovery of resources to deploy next VNF instance, but with limited control over HW resources. Using latest Redfish compliant APIs, it is possible to extend closed-loop automation capabilities from Orchestration to deployment ready HW resource. In order to use these dynamic controls, the Orchestrator must be aware of workload types and communicate the policy to the VIM Manager to maintain a closed-loop control framework. Such framework should be capable of performing these essential tasks: Mapping Telemetry events to an Action, Dispatching Actions to workload deployment flow including HW bring-up or tear-down, Updating available HW resources to inventory database. The proposed framework is a generic design which can incorporate the aforementioned tasks for managing scalable workloads in NFV Cluster.
