Question

Your engineering team has identified a problem. Whenever an application becomes popular, the resulting high-traffic load on the VNFs leads to user dissatisfaction. Which Contrail feature would be used to solve this problem?

Answer 1

To solve the problem of VNFs being overwhelmed by high traffic, Contrail's auto-scaling feature is used to deploy additional VNF instances, maintaining service performance.

Step-by-step explanation:

The engineering problem described pertains to VNFs (Virtual Network Functions) becoming overwhelmed due to high traffic when an application becomes popular. To address user dissatisfaction that arises from this, the Contrail feature that is typically used is scaling out or auto-scaling of the VNF instances. Contrail provides a cloud-networking platform that can orchestrate the creation of additional instances of VNFs to handle increased load. This is done through policies that detect when the load on current VNFs is too high and then automates the deployment of additional resources to balance the load and maintain performance.
