 * If using virtual machines for compute resources and they have low utilization, consider reducing the size of those virtual machines to increase utilization. Smaller virtual machines with higher utilization usually use less energy than larger virtual machines with lower utilization given the same workload.
 * Evaluate migrating your workload to a PaaS where possible. Typically, PaaS solutions are sized more appropriately for their workload and can run those workloads at a high utilization on their underlying compute resources.
