+To trigger the scale out workflow manually, the user/network operator can log into VID from the ONAP Portal (demo/demo123456! as username/password), select "VNF Changes" and then the "New (+)" button. The user/network operator needs to fill in the "VNF Change Form" by selecting Subscriber, Service Type, NF Role, Model Version, VNF, Scale Out from the Workflow dropdown window, and insert the JSON path array described above in the "Configuration Parameter" box. After clicking "Next", in the following window the user/network operator has to select the VF Module to scale by clicking on the VNF and then on the appropriate VF Module checkbox. Finally, by clicking on the "Schedule" button, the scale out use case will run as described above.

+Automated scale out requires the user to onboard a DCAE blueprint in SDC when creating the service. To design a closed loop for scale out, the user needs to access the CLAMP GUI (https://clamp.api.simpledemo.onap.org:30258/designer/index.html) and execute the following operations:
+- Click the "Closed loop" dropdown window and select "Open CL"
+- Select the closed loop model and click "OK"
+- In the next screen, click the "Policy" box to create a policy for closed loop, including guard policies
+- After creating the policies, click "TCA" and review the blueprint uploaded during service creation and distributed by SDC to CLAMP
+- Click the "Manage" dropdown and then "Submit" to push the policies to the Policy Engine
+- From the same "Manage" dropdown, click "Deploy" to deploy the TCA blueprint to DCAE
+
+The vLB/vDNS VNF generates traffic and reports metrics to the VES collector in the DCAE platform. The number of incoming packets to the vLB is used to evaluate the policy defined for closed loop. If the provided threshold is crossed, DCAE generates an event that reaches the Policy Engine, which in turn activates the scale out closed loop described above.
