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

Business Requirement
Executive Summary
Dynamic scaling gives an operator the tools it needs to maximize efficiency of the resources dedicated to the cloud. Through the Scaling Use Case, 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.
Business Impact
Enabling dynamic resource allocation through Scale Out and Scale In will greatly increase the efficiency of the Cloud Platform. This will be one of the key methods for meeting the cost savings that Cloud Platforms have promised Service Providers.
Business Markets
This Use Case will be important to any provider that is trying to maximize its use of limited resources on a cloud platform
Funding/Financial Impacts
This use Case has the potential to significantly reduce CAPEX
Organizational Mgmt/Sales Strategies
There is no additional organizational management or sales strategies for this use case outside of a service providers "normal" ONAP deployment and its attendant organizational resources from a service provider
Participating Companies
AT&T, Ericsson, Nokia, Tech Mahindra
