The problem describes demand spikes where capacity exists, but the application cannot meet demand—this typically indicates the cluster needs toscale out(more nodes/pods) automatically when load increases. In VCF 9.0, VKS supportsCluster Autoscaleras an optional package and specifically calls out improvements: “Cluster Autoscaler supports scaling from zero or to zero… You must have the autoscaler standard package installed.” This directly supports optionA(install cluster autoscaling) as the mechanism to dynamically add capacity during peak events and reduce it afterward, optimizing cost and operations while meeting bursts. A load balancer (including Foundation Load Balancer) helps distribute traffic acrossexistingendpoints, but it does not create new compute capacity when pods are pending due to insufficient nodes. Similarly, installing Contour relates to ingress (routing inbound traffic) and is not, by itself, a capacity scaling solution. Oversubscription is a risky workaround that can degrade performance and does not provide targeted, policy-driven elasticity. Therefore, enablingcluster autoscalingis the correct way to address burst demand when underlying resources are available.
