DTSPO-17851
Summary
Intended Outcome
Output of spike documented
Plum/Toffee pipeline runs and builds successful
Horizontal Pod Autoscaler (HPA), Kubernetes Event Driven Autoscaling (KEDA), and Vertical Pod Autoscaler (VPA) are enabled on the cluster and tested successfully
Impact on Teams
How will this impact teams, put 'No impact' if none
