<p>Nordstrom Technology developers using Kubernetes now deploy faster and can "just focus on writing applications," says Dhawal Patel, a senior engineer on the team building a Kubernetes enterprise platform for Nordstrom. Furthermore, the team has increased Ops efficiency, improving CPU utilization from 5x to 12x depending on the workload. "We run thousands of virtual machines (VMs), but aren't effectively using all those resources," says Patel. "With Kubernetes, without even trying to make our cluster efficient, we are currently at a 10x increase."</p>

<p>Speed is great, and easily demonstrated, but perhaps the bigger impact lies in the operational efficiency.
