Overview
One of the primary advantages of a virtualized cloud infrastructure is the ability to maximize resource utilization. In a PNF environment, resource allocation is relatively static and therefore enough capacity needs to be available for peak loads. This leads to many inefficiencies during normal operating times. In the software controlled environment of virtualized resources, ONAP can allocate resources to a VNF as they are needed. Scaling is the process utilized by ONAP to change the amount of resources allocated to a VNF
Dublin Goals
- Manual Scale In (Manually remove instances of a VNFC)
- Auto Scale In (Automatically remove instances of a VNFC)
- Auto VNF Configuration
- Updates to Manual and Auto Scale Out
- Homing and Capacity Check
- Architecture approved Controller_Type Lookup
- Support TOSCA Based VNFs
Business Requirement
Dynamic scaling gives an operator the tools it needs to maximize efficiency of the resources dedicated to the cloud. ONAP's control environment allows it to assign resources where they are most needed and reallocate them when they are needed by different VNF. This allows the cloud environment to achieve a much higher resource utilization level than the old data centers it is replacing.
Past releases of ONAP have developed the capability of adding additional resources (VMs/VF_Modules) to a VNF as the demand for the VNF grows. In the Dublin release we will add the capability to reduce the number of resources (VMs/VF_Modules) assigned to a VNF so that those resources can be used by other VNFs as needed.
