  People at Ocado Technology have been quite amazed. They ask, ‘Can we do this on a Dev cluster?’ and 10 minutes later we have rolled out something that is deployed across the cluster. The speed from idea to implementation to deployment is amazing.

 <h2>Impact</h2>
      With Kubernetes, "the speed from idea to implementation to deployment is amazing," says Bryant. "I’ve seen features go from development to production inside of a week now. In the old world, a new application deployment could easily take over a month." And because there are no longer restrictive deployment windows in the warehouses, the rate of deployments has gone from as few as two per week to dozens per week. Ocado has also achieved cost savings because Kubernetes gives the team the ability to have more fine-grained resource allocation. Says DevOps Team Leader Kevin McCormack: "We have more confidence in the resource allocation/separation features of Kubernetes, so we have been able to migrate from around 10 fleet clusters to one Kubernetes cluster." The team also uses <a href="https://prometheus.io/">Prometheus</a> and <a href="https://grafana.com/">Grafana</a> to visualize resource allocation, and makes the data available to developers. "The increased visibility offered by Prometheus means developers are more aware of what they are using and how their use impacts others, especially since we now have one shared cluster," says McCormack. "I’d estimate that we use about 15-25% less hardware resources to host the same applications in Kubernetes in our test environments."
